I wanted to take the bus for a quick spin today, but had all kinds of problems.
Batteries were low so it wouldn't turn over. I charged the batteries for about 30 minutes and it started. The stop engine light came on within 60 seconds and the engine shut down. I tried it again with same result. Checked the codes and found an code 43. Code 43 is low coolant. I added a little coolant and the engine stayed running now.
The air compressor governor was frozen so no air pressure would build. I decided to leave the engine idling at about 1,200 RPM and it finally warmed things up enough after 15 or 20 minutes to go. (I have a Series 60 so the idling isn't quite as bad for it.)
All in all it took me a good 90 minutes of monkeying around to make a 30 minute trip. I just wanted to take the bus out to charge the battery, get it wamred up fully, and to top off the tank for winter.
You should really get into the habit of a pre-check including ALL fluid levels before ANY trip, long or short!
Also it would be highly adviseable to invest in a marine on-board battery charger that simply plugs into a 110 outlet and keeps your batteries fully maintained while sitting idle for long periods! You won't have nearly as much to post about in a negative way and your bus adventures will be much more pleasurable!

i just tied my start batteries onto my house batteries so they can stay charged just like the house batteries do, off the inverter. i got an isolator switch that i can disconnect the two sets when i want, connect them back up when i want.
better than having a separate charger? i don't know, just thought i'd post it in case Ace (or anyone else) had a good reason why i shouldn't do what i did. otherwise, looks like i saved buying a separate charger.
Only problem I can think of is Poor Memory?? Jusy Kiddin' The only problem would be IF you forgot to disconnect them when dry camping. After a week at YeeHaw, you could find all your batteries low. Jack
I have a battery maintainer that needs to be installed which I will do this week. I was hoping that a month or 6 weeks wasn't enough to draw down the batteries. Dina in their infinite wisdom doesn't shut everything off with the battery disconnect. The DDEC, WTEC, and passenger clock are always sucking power.
Brian, the low coolant code should be programmed to only activate the check engine light and not shut the engine down. This can be done with a ProLink by any decent diesel mechanic.
I checked mine, as I have a very small loss of fluid and it frequently trips the low coolant PID. Even though I made sure mine was set to only trigger the check engine light, it still trips both but does not de-rate the engine or shut the engine down.

The error code listing for Series 60 codes say that code 43 low coolant is a critical error. Critcal errors will shut the engine down. The two other critical errors are high coolant/oil temps and low oil pressure.
My coach has always shut down when coolant is low although when I had a major leak on the highway the engine never shut down due to low coolant. I ended up putting something like 3 gallons in that time after making the repair.
Belfert; the RV safety guy is telling you to reprogram the 43 critical code then code 44 will still protect your engine it done every day the low coolant 43 code is a pain.
have a good day
Checking coolant is something I rarely do because Dina makes it very difficult to do so. There is no sight glass or any visual indication of the level of the coolant. About the only way to check is to open the cap on the expansion tank and stick a finger down inside. When filling I just have to keep filling until coolant leaks out as there is no way to see the coolant level.
I should check it before every trip, but I usually only do it before long trips since it isn't easy to do. For now I'll probably just leave the coolant level as a critical code since it would cost money to have it changed.
I still don't understand why you don't keep your inverter on float while parked in your driveway, and have the start batteries tied into the house bank. One small wire with alligator clips on each end would keep them happy if they both banks were charged to begin with. You could hook it up manually when you park, and unhook it when you go driving. Or connect the proper sized wire through a switch or relay for a permanent crossover connection.
The air governor thing is your own fault, as you had the same problem last year, and didn't fix it when it was warm.
BTDT.
The coolant problem is your own fault, aslo, as you didn't do a proper precheck, and you should know by now that when cold weather hits here in MN, all your clamps are subject to leaking. You have to go out every fall and tighten every clamp on your bus, or you can potentially lose several gallons of antifreeze. That's just part of living here and owning a bus here, and if I'm not mistaken, you brought up the same coolant loss issue last winter.
I haven't done that yet, and will probably have to add a few gallons to mine next time I start it up.

If you suffer from CRS as I do, you could use a relay controlled by 120 volt shore power to tie the two batteries together only when power is available.
Fellows, I don't use my inverter to keep the batteries charged for long periods of time only when I am on the road, after 2 shipping bills to WA state and bills from Trace I use the battery maintainers for long periods I can buy those for around 60 bucks so far it has worked good for me.I don't understand why he has a battery maintainer just laying around it only takes a few minutes to install
good luck
The battery maintainer is probably a couple hour install to do it right which is why it keeps getting put off. I need to run a 110 volt circuit for the maintainer. For now I am just going to run an extension cord and install it temporarily until Spring.
The last coolant issue I had during the winter was a constant drip frm a bad radiator cap. I don't see any leaks right now and I think the need for coolant was just from change of seasons. I also had to add a very small amount of coolant to my VW Golf this past weekend or the low coolant alarm would go off only in the morning when the car had sat in the cold overnight. No leaks I can find and VW says it is normal to have to add coolant every winter.

I forgot all about it over the summer. I had intended to move the house batteries and that has not happened yet. I have new batteries and stuff to mount them, but I ran out of time before my last trip of the season. I probably won't do it this winter unless I get really ambitious and use a couple of electric heaters to warm up the bus.
Once I remove the 480 pounds of batteries plus the battery tray to get to the compressor to replace the governor I certainly am not going to put them back in.
I still don't know how just replacing the governor will fix the problems with water in the system. I am going to go over the air system in the spring/summer when it warms up to try and get any water out of the system. I still have an issue with air leaking down once it gets down below 40 degrees. In warm weather the air will stay up indefinitely. A bus mechanic I asked about it said just to live with it.
belfert....Did you have trouble with the air governor in the summer time? If not, but only during freezing temperature....then read on...( from earlier post) Belfert....first of all...did you ever fully all air tank before freezing season? This is a must do procedure so that all water is drain before it turn into ice in air tanks or you will the problem of air line clogged with frozen ice and all the control valves including governor. Even if got full air pressure in tanks, you will gamble if the foot control valve will freeze later into NO BRAKE. I been there and done that at a meat packing house. I was their mechanic to maintain a fleet of trucks in mid Michigan.
Even after engine warmed up will not get remove ice because leaking air will act like Freon does to make things colder than surrounding air temperature.
Your only choice is to wait until it ambient temperature is above 32°F or tow it into a warmed shop to thaw and fully drained all the air brake system.
You can run alcohol thorough the system (if you get the alcohol liquid to the ice in the first place) however it will remove lubricant from all air control valves this time. You still will not remove all ice out even after it working...later it start same problem all over again.
Normally OEM equips optional alcohol system is used in very small vapor amount to prevent washing out the lube in all the control valves system.
The bottom-line you need to thaw the whole bus to drain the water out before into freezing driving condition.
About why water get into air lines & tanks. Whenever ambient air above freezing temperature and humidity present, air compressor is pumping that humid air into your brake system to condense into liquid state equal water.
Air filter/purger is only good for warmed and very small amount of water vapor to help keep it from building small amount water being stored in the air tanks.
Again to remind you to do the important step first....do what the first paragraph mentions. No need to replace parts yet until after thawed and tested.
FWIW
Sojourn for Christ, Gerald
This will be my final post on this topic.
Ace,
I am sorry to be negative, but it seems that every major trip I do I have issues. I have done four major trips to date and had problems on three of the four.
Trip #1: The engine was leaking a quart of oil an hour. Now, I knew this in advance and part of the trip was to get the problem fixed so maybe this doesn't count.
Trip #2: Serious coolant leak near water pump. Radiator and water pump had been replaced and one hose and clamp wasn't centered properly. We spent three hours fixing this on the road by adding another clamp and replacing lost coolant. This problem took about 1000 miles to show up. The bus had been test run and taken on short trips after the repairs with no issues. This repair is still holding over 7,000 miles later. I do carry spare hose and clamps just in case things like this happen.
Trip #3: 1,600 miles with no issues I can recall.
Trip #4: Short developed in rear tail lights as we were leaving. We spent 90 minutes rewiring the rear tail lights to a constant 12 volt source. Bus had been test run a few days before to hopefully work any bugs out. We noticed the tail light fuse blown, but a replacement fixed it. The day we left the fuse would blow as soon as lights turned on. At our destination I checked the wiring harness from front to back and couldn't find anything wrong. I will look at again in the spring.
I have had terrible issues getting my windows to seal to the body which was a major reason for redoing the interior this summer. I am pretty sure the window issue has been fixed for now. I have been checking after each rainfall and no puddles inside like before.
It is human nature to complain about things. Ask any retail store how many complaints they get versus compliments.
I admit I need to keep a better log of issues so they get fixed. I also need to be sure to do a complete pre-trip on every trip, even short ones like this weekend. I probably spend as much time on preventive maintenance and repairs in a year as I ever do driving the bus.
I would just like to get through one major trip without a show stopper issue that has to be fixed to continue the trip. I will admit that most of my issues have been very minor compared to blown engines, blown trannies, and other major expensive repairs. I haven't had to be towed or call a service truck and all the repairs were done without going to a shop so that is good. I don't expect a bus to be as problem free as my car, but neither do I like constant repairs.
The bus is parked for the winter now so I will have to deal with the air system in the spring. The rear tanks have auto drains so I don't know if they aren't working or what. I suppose putting in manual drains might be a good idea.
Scrap auto drains. They do not work very well.
Neat idea in theory, don't work in practice, and Doctor Busnut wants to see what comes out....
happy coaching!
