Title: Help with GM 4104
Post by: harleyman_1000 on August 08, 2013, 11:09:56 AM
 Ok I finally bought my first bus. It is a GM 4104. I am currently broke down and in desperate need of some information. I need to know where the fuse boxes are? I found 1 small fuse box inside the panel to the left of the driver seat, but it only has 5 or 6 fuses in it, so Im sure there is another fuse box somewhere? I called the guy I bought it from and he didn't know where it was? I don't have any tail lights, brake lights, or rear marker lights, but the turn signals do work, so Im guessing it is a fuse?  If you can help please call me since my internet doesn't work well here.  Scott 573-705-011 four

TRYING TO HELP UNTIL OTHERS RESPOND

http://www.busconversions.com/bbs/index.php?topic=19551.0 (http://www.busconversions.com/bbs/index.php?topic=19551.0)

according to this post there are no fuses, just circuit breakers, there is a box in the back (by engine?) that can corrode and have loose connections

good luck

A wiring diagram may not do him much good on that bus just find the junction box of breaker one will feed that circuit from a relay some place

closely check wiring and grounds at tailgate and harness going to it at top of engine compartment. You need to get yourself a test light from an auto parts store and probe connections there.

Thinking out loud - Day and night mode on master?  Possibly someone did some rewiring and grabbed power from circuits only energized at night mode instead of day???

Scott (Harleyman 1000) just left my shop and is headed to Flagstaff 5pm Sunday.  I got his engine running correctly and then spent several days helping him straighten out the wiring.

He says he is going to stop at an Eagle Rally on his way back to St. Louis.

Thanks geoff.  talked to him several days ago.

He was having a tough time for a new bus owner. always good to find a busnut to help.

How did the t drive in a 04 look. I saw the coach at Daytona bike rally quite a few years ago but could not find any one to talk to or let me get a good look.

Hey guys, Im almost at Flagstaff, and it's 2:38 am. I was blowing alot of black smoke all the way here, and head lights kept going on and off( made driving thru the mountains in the dark very interesting). Im parked at a  camping world and there is a Harley dealer next door. Im thinking I might have found the right spot to park for the night  ;D  Hey Clifford, I lost all my numbers when my old phone died, so please call me   573-705-0114

I assume somone has told you to not use the fuel pedal so much to control the smoke.  At that altitude you loose about 20% of your engine performance so be extra soft on the fuel petal.  It will be a dog with or without the black smoke so save some money on the black Unburnt fuel.  My lights used to dim severely everytime my factory ac/heater blower motors would kick in. They pull lots of 12v juice.  Is that system cycling on and off causing a problem or short?

Im not using the factory heating or cooling, and there going totally off for like 30 seconds then coming back on. Other times they just flicker on and off like a loose wire, but since it works more often than it doesn't Im thinking it isn't a loose wire?

Are you going to tow my bus back to St.Louis, so I can use the saved gas money to buy the new wiper motor, inverter, refrigerator, and satellite system I need for the bus?   :(
Title: Re: Help with GM 4104
Post by: Len Silva on August 12, 2013, 11:10:16 AM
The headlight factory wiring is very simple, no relays or fuses involved.  You can get a wiring diagram here:  http://manuals.lenstudio.com/GM_PD4104MaintX-5818.pdf (http://manuals.lenstudio.com/GM_PD4104MaintX-5818.pdf)

In the meantime, here is the circuit (assuming previous owners haven't screwed it all up)

In the drivers panel from Breaker 11 to term 21 to the headlamp switch.  From there back to term 62 or 82, can't read it.  From there to the head lamp/fog lamp switch and from there to the dimmer switch and on to the headlights.

So, does it do the same thing on high or low beam?  The problem is before the dimmer, if not, it is after the dimmer.  The dimmer switch itself is a likely suspect, it is a pretty harsh environment in the tool compartment.

Good luck.

My dimmer switch will cause the lights to go completely out if I hit it at the wrong angle. They have always come back on when I hit it the second time. It's been a long time since I have done a night trip. This reminded me to order a new one!

Those dimmer foot switches are very prone to rust, especially when not used for a while.

That is a link to my bus. I made it home. I replaced the fuse box and the lights never went out again.

Having a pretty bus, as Scott's is, is great, But having dependable, fully functional house systems, and a mechanically sound bus is much higher on my list of importance. With our old buses it takes a while to get them into that condition and constant maintenance to keep them there. I know I enjoy working on our bus to keep it in good condition, and have most of the skills to do so, but not everyone does. Those who don't enjoy working on their buses or have the skills, will need to find a reliable person(s) to keep them up, and be willing and able to pay for their services.

Good luck, Sam

You guys know why getting divorced is expensive, right?


Because it's worth it!   


My ex insisted she get my motorcycle and enclosed car trailer.  The judge asked her if she rode a motorcycle.  "No".   Then the judge asked if she owned a vehicle to tow the trailer with.  She said "No".  I ended up paying her the cash value.  Scott, PM me and get her info to you!   Lol!!
