On pin 3 of the control module, do you have 12vdc when cranking motor?

After you apply the 12v and you remove the jumper does it still continue to put out the 110v?

2 of your numbers look like they could be off just enough for it not to output power. Your fixed excitation voltage is low and your 42 ohm is high. These are actually inter related. A higher ohm rating will give a lower excitation voltage.
Try doing the 42 ohm line test again but put your negative meter probe right on the generator case (not motor case) if you can find a nice clean spot.

Your welcome. Please post back when you have your results.

At this point I think 2 things need to be addressed. 1) Change the battery, or at least try to fully charge it and let it set for 24hrs and see if it maintains at least 12.6v ... 12.32v is no good 2) Replace that starter relay. I know you wanted to try to see if everything works before putting any parts in this but I don't think you realize what is not happening when you try to jump that relay. Even though when you are jumping that relay for the engine to crank and even though you are compensating by making sure you are sending battery voltage to pin J1-13 on the controller...... you are failing to temporarily ground pin J1-6 which actually aids in activating the controller. This could be why you had no spark when cranking the engine. In this type system, almost everything has to be working and in sync with each other or nothing works.
I think having a good battery in there and replacing that starter relay and everything will work fine.

That battery voltage is to low, even though it also appears that the relay is bad. Battery voltage should be at least 12.6 so you may have a bad battery that even charging won't help. But lets do 1 more test but throw a charger on that battery if you can.
Take your test light and connect the clip to good ground. Then put probe on J1-1 which is for the relay wire you have disconnected. Leave it disconnected but make sure the end is not touching ground anywhere. Then press the start button(SW1) and see if your test light comes on.
Also, what is the voltage right on the battery?

If you remove the small wire (56) from the relay and set it aside and then take a jumper wire (preferably one with an alligator clip) and attach it to the small terminal(56) and then touch the other end of the wire to the large lug on the starter relay with the battery postive (+), does the relay: click? and turn the engine over?

What I have found over the years is that many times the problem is just a bad connection somewhere. Especially since it is mostly in the weather even if it is under the rig. And don't forget about ground connections. These are sometimes over looked.
Where your main battery ground cable is attached to the lug that is bolted to the generator, use your ohm meter and make sure you have a good connection between the cable wires and the generator frame. Then also test for low ohm reading from ground cable to the small connector on the starter relay (0). If ok then remove the other small wire (56) from the starter relay and then ohm test from ground wire to the small terminal you removed the wire from. If it reads somewhere around 2 to 25 ohms or close then reattach the wire and then ohm test from ground wire to pin J1-1 of the controller and see if reading is around the same. Also check for low ohm reading from ground wire to pin J1-12 of the controller and the center terminal of the start switch (SW1).
Let me know what you get.

Ok, now you are just going all over the place. Slow down and take a deep breath, lol. If the red led on the voltage regulator was lit when you last had it running means it was working properly and the generator was probably outputting power. So forget about that regulator for now. And by all means stop poking at it, haha. Sometimes things get broken from to much poking. Now I am very meticulous when it comes to diagnostics which is why i am always successful. So I would like you to do what I ask and nothing else. Just short answers with your results. So why do you believe the starter relay is bad?

Ok, I have read through mostly everything you have posted and I want to start in 1 place and then go from there. So if I do not address any of your specific questions it is because that will come as we go along.
So when you say in your last post that you connected a relay that puts voltage on the regulator, do you mean it puts voltage on pin 13 of the control module?

I have to run out but I will respond when I return. It might be better if you register to the forum because i do not currently get notifications when you respond in the thread.

Yes I am still around. Just not much going on in this section, lol.
So lets see. First I need the model number of your generator so i know exactly what you have. Should be 9 thousand something dash something.
Second, do you have a 12v test light or a digital volt meter or both?

Did you check the circuit breaker as posted earlier?

I still don't quite get what you are saying but if you were to test at an outlet and it cycles at the 160v volt there, then you definitely have a regulator problem. Replacement would be required.

Are you testing across both breakers at the same time or 1 breaker at a time with your negative probe on ground?
