Engine safety shutdown circuit ? ? ?

[kyle4501]

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?

[kyle4501]

Nothing like that in the engine compartment.
I'll have to look under the dash.

Is there a system without a control module?

Yes

[kyle4501]

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....

so..no ddec ?

[kyle4501]

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...
