So, I had some light engine work done & shortly afterwards, the engine fan ate some wiring. It took all the wires going to the radiator sensors & I don't know what else.
The coach still runs fine - I just don't trust any of the wiring to the sensors.
Electrical troubleshooting is definitely not something that comes naturally to me.
Since there are no schematics available for this coach, does anyone have anything that could help me figure out what I have / should have?
Thanks,
Kyle
Newell used the Kysor system on the mechanical 8v92,you should be able to download the manual off the net if not I can send mine to you and you can copy it.
It is a fairly simple system even for me.Kysor has changed owners and names several times over the years but they are still the same.Only other system I saw Blades use was a Murphy if so I cannot help you
All of the wires should be color coded and, or numbered. Shut off your main battery switch and reattach each wire to the correct corresponding wire, then everything should be back to normal.

After 30 years, who knows what idiots have done in the past - I have already found wires that have been spliced with no regard to colors.
Also, when the fan ate the wiring, it pulled some out of the wire loom - so that is not an option.
THANKS Luvrbus,

BTW, Any suggestions where I might find the module ?
look like this?

Nothing like that in the engine compartment.
I'll have to look under the dash.
Is there a system without a control module?

Yes
I haven't found that yet - either too old for the internet or I'm not using the right key words. . .

What year, what motor?
Kysor Cadillac was the major player in the mid 80's
Murphy used humongous sensors....

Nope, all mechanical . . . .
The only box I could find is a Super ISSPROLARM. It is under the dash and is a low coolant level alarm.
I'm beginning to think it may be easier to put in a simple marine engine warning buzzer kit - a buzzer & light should catch my attention. . . .

IMO..no light or buzzer alarm is fast enough to save a Detroit meltdown it needs to shut er down before uncontrolled heat evolves...
your coach...

The manufacturer built them that way because they know sumthin!
Kyle,
You probably found this already. http://www.isspro.com/installation/IS049.pdf (http://www.isspro.com/installation/IS049.pdf)
Thanks Richard.
According to what I have found, the alarms go off at one setting & shut down at another
For 2 stroke DD
- alarm at 6 psi & shut down at 3 psi oil pressure
- alarm at 204 F & shut down at 210 F
The automatic shut down has an over ride switch.
I'm not sure I want something turning my engine off - I've had some false stops that were inconvenient at best and dangerous at worst.
A functioning warning system is better than nothing.
Kyle, the radiator sensor and light on your coach is for low level water that one will not shut the engine down,you should have 2-Kysor/Cadillac alarm stats 1 ea on each thermostat housing with 3 or 4 wires they come in different temperatures ranges up to 225F
I don't know what you have, it will have the range marked on the alarm stat.Low oil pressure buzzer or the warning light are to warn the operator to shut the engine down if oil pressure is below 3 lbs.
I never saw a mechanical 8v92 wired to shut down for low oil pressure unless it was a Murphy system and you needed to push the button by hand on the gauge past 5 lbs to start the engine.
On the alarm stats it has to complete the circuit to shut your engine off,heat is the only thing that will shut your engine down if it has the Detroit Kysor/Cadillac alarm stats not low oil pressure that one is on you ;D
Thanks luvrbus. The pass side T-stat housing has a small sending unit with 1 terminal. The drive side T-stat housing has 4 terminals. The upper radiator tank has 2 sensors - a 1 terminal, & the other has 2 terminals. There are 2 oil sending units above the starter, again a single terminal & a dual terminal.
I can't get to the 4 terminal sensor in the T-stat well enough to see any labels, hope to find out this weekend.
1 terminal senders are usually for the gauge 2 terminals are for the warning light or buzzer
