Good chance it's a MCCK can you find the serial
number? I had one of these in my f32 trojan what's going with it?

Unless it was replaced it is indeed an Onan MCCK 6.5. I have an 84 3697 as well with this genset, let me know if you have any questions- I'll do my best to help!

Thanks Guys... Somebody was messing with it and I think stole one of the heat sensors.. Nice... I'm guessing not easy parts to find.

If it's an MCCK, parts are out there but typically pricey. Some parts are obsolete on earlier specs but likely available on-line The MCCK units are pretty much all the same with some minor engine component differences over the years, and control and generator assembly changes. You'll need to know the spec; A, B, C, etc. to ensure you get the right parts.

Why do you "think" a sensor is missing and what is the unit doing/not doing? Is it running?

[dmunneke]

I think its missing because its not on the exhaust elbow and the wire is there without the sensor attached to it..

No the think part is why its missing.. I didnt take it off !

Have you tried running it? I believe the switch is NC (normally closed) so jumping the two wires will complete the ignition circuit. You shouldn't use the unit without the switch but this will allow you to see if it actually runs if you've never had it running before.

Yeah thats exactly the plan.. It has run perfectly but I haven't had it running for a couple years now.. Its going to require some tinkering.. I havent tried to fire it yet since I noticed the missing part
