P47A goes to terminal 5. It should be hot. When you put the S2 in the start position, the S2-5 makes contact with S2-6, wire P45B. Thats the terminal you want, not S2-9. The schematic shows the numbers upside down, or so faded you cant read them! I am beginning to hate this crap. Way to many mistakes!!

Will test P45B

Tried to start the engine at 20 sec run intervals. 7 times. The starter was getting hot so I quit.
This was with the jumped connector and no battle start. Need to recharge the batteries but they were running strong

I firmly believe if we can get VDC to the IP the engine will start. But I don't know how this wiring spaghetti gets there. Also the lift pumps needs to be working in the run mode

OK. You got 24VDC at the G&H jumper in start. THAT'S GOOD! Now if the batteries are charged, I want you to test at the IP. Leave the jumpers in P37 C-Plug. Go to the IP, and remove wire P80N. Test VDC, nothing else. Not continuity or anything else, as VDC is what we are looking for. From ground to P80N. You test, someone else holds the S2 in the start mode. What do you get? 24 VDC?

This is the IP fixen to be tested and the wire off.
Please look at the wire holding I guess the throttle.
Is this in the correct position?
Battery is still charging

Should look just like this one. Why is the wire there? well, there are three models of this gen set. The Utility, (yours) the Precise 60 hertz model, and the Precise 400 hertz model. Your model has no governor. The other two do. The Electric governor, controls the engine speed by telling an electric Actuator, (also not on your set) what speed to run the engine. The actuator is mounted above the IP, and the linkage is connected to the front, (The arm on yours wired forward)) IP control arm. BUT leave it as is. The

So, no worry Kris

OK. now take out the jumpers, hook up the J37 and do the very same test. P80N to ground. If you get 24VDC, hook up the P80N to the IP. Then look to your left and up top to the last Injector line. Take a 7/8 wrench, (I think that's the size) and crack the line. Just loosen it a turn or 1.5 turns. Crank the engine over. Are you getting fuel out of the line? If so, it might start. If it will, run it a few seconds, then turn it off.
