The relays are likely Bosch type automotive relays. 5 pins. Got a picture?

https://www.delcity.net/store/5-Pin-..._73576.h_73663

Part 73980 12 volt look like the 1CR and 2CR relays.. Many other sources besides Dell City.
the C relay is much larger, I believe. The C relay is good as it controlled the starter function, and as you indicated, that is working. The RR relay might be comparable with the 5 pin relay if wired correctly..

If you have a diagram can you scan it and put it up here? But I think the one I added below is correct.

Try here, there is a 7.5 parts manual and perhaps some other info

This may be what your controller looks like, it is for a 7.5

Matt,
I know this is a bit north of you, but there is a great Generator shop up in Flagstaff... They did work on my powertech and did a good job at a reasonable price...
They replaced my water pump and removed and cleaned the radiator...

Q: Does anyone know a great generator repair shop in the Phoenix area? I think the unit will run with the right troubleshooter. Also, are these relay parts still available?

Thanks,

Have you traced those wires ? Could they be from a high temp sensor,low oil pressure sensor, does your unit have a Mag or distributor? The 7.5 in our houseboat will ground out the mag so no spark ?

Matt there's a link to the Service Centers that have been used by WOG members in my signature. If you're still in need there is one referenced just north of Phoenix that NoGas has used and it references genny service.

About a month ago I utilized one of the few people in the Phoenix area that knows Kohler generators(Robert @ Issco Generators). He spent several hours comparing wiring with the proper schematic and testing circuits. In the end he decided that the 'auto cranking' which was occuring when the loose black wire was connected was due to the previous owner installing the wrong starter solenoid after the original was destroyed.

I ordered the proper solenoid from Kohler and installed it with my fingers crossed. Well, the good news is that the 'auto cranking' issue is gone with everything connected, the bad is that now I get nothing when I try the start switches. I hear a small click when I connected the control box, but nothing happens when I try to start.

Question: Does anybody know where I could find a used Control Box for this genset? I think that one of the relays inside(clear plastic - has 3) is bad. There is a picture in one of my previous posts.

Thanks!
Matt

ps, Randy, I drained the questionable gas so if I can get her cranking that won't be on the list.

Matt, I.am a little confused here. See if I have this correct.
1. Original problem was it would crank but not run and a wire was torn loose that we don't know where it connects.
2. Solenoid change and now won't crank at all.

Questions:
Where did you connect the loose wire ?
Do you have 12v+ to the small wire on the starter solenoid when try to start ?
When you do get it to crank over.
Do you have fuel pressure ?
Do you have spark ?

It sounds like you are about to throw expensive parts at this in an attempt to fix it and that may not be the solution. I find it hard to believe that an experienced generator tech spent several hours poring over schematics for this and didn't fix the problem.
They are complicated but not THAT complicated. Sounds like you are in over your head. I would suggest another tech.
JMHO ( worth exactly what you paid for it )

Sort of correct. Not over my head, just fixing someone else's mess. The wire belonged on the lower post of the correct starter solenoid. As I said, the problem is now probably in the control box. Q:is there a simple way to bypass the individual relays inside the box? Once I get it to fire again, I will check if I have pressure or spark. Crack kohler gen techs are far and few.

Thanks,
M

It that thread they say you have a 4 cylinder water cooled engine.
Those little engines are pretty cool,but i have found no info on where to get parts etc (for the engine).
I have a similar engine (Waukesha) and i was researching kinda hard for a while.
You may get that old girl running and working,but i would not put many dollars in it..
