This is where I should say to you, "Read the manuals!"
But, being a nice, harmless old man, I will tell you. Take off the rear, top of the set. Remember, the control panel end of a gen set is ALWAYS the rear. You have to remove the control panel cover, (door) at the same time. In the space behind the control cube, above the K-1 relay, you will find the TB-4. TB stands for Terminal Board. If you take a gander at almost any part in the control panel, as well as the rest of the set, you will often find that someone printed things next to the parts. Next to every TB on the set, should be the TB number, like TB-4. Next to the relays should the relay numbers, for example, K-1 or K-16. And so on. Helps when you have to start looking for things and are not familiar with the set. Hint, Try not to drop the nuts into the control panel when removing the top cover. Hint, always disconnect the negative side of the batteries when doing work on the control panel, if you are not familiar with where is "hot", DC voltage, and where is not. Even with all switches off, and the emergency stop pushed in, there is 24 volts present in the control cube, and behind it. Some people find it a PITA to remove the clamp, and then hook it back up to troubleshoot. Burn up the wire harness once, and you might change your mind about that. It was an nice refreshing chore to replace the control cube wire harness one night in Vilseck, just before the unit deployed. And no, your not dumb. But do get the books and read them.
