No AC output

[240hippie]

802a. Yes I have the manual. Ran generator a month ago for power outage, all good. Went to start and run a couple weeks later, no power on the gauge. No generator output. Went thru manual trouble shoot. Pulled top panel, found ground wire burnt in half. This wire went to a long bridge. was #9 on the bridge. Checked the main contactor, cleaned it. Checked all connections. Repaired ground, test ground thru existing grounds, good. Not having any luck with the troubleshooter at this point. Any ideas, would be helpful. Thanks

1. Do you have the Quad circuit Mod on the gen set?
2. If so, have you checked the fuse?

Burnt grounds don't 'just happen'. I think that needs to be thoroughly fleshed out, before you worry about AC out. Would hate for YOU to become the ground.

Have you removed the roof panel over the operator controls, to look at the entire area 'where the magic happens'?

Yes I know grounds just dont fail. But the manual is kinda lost with the generator trouble shoot. Yes I know I have to "flesh" things out, this would be why I am asking.

Yes, I took K1 apart, it is like new inside. TB4 terminal #9 is a ground. The wire was burnt. Rep[laced the wire. The issue is the manual is lacking on troubleshoot for the generator output.

Quad is modified , has fuse and veristor. All good. The ground wire was melted, dont have a number. A "bridge" is a place were multiple wires are connected. . TB4 is the "bridge I am speaking about. . Took K1 apart, like new inside. Tap it with a small hammer, tap not hit. All of this was in my 1st message

802a, looked thru all of you pdf's, have a manual down loaded. Not very helpful. My 802a was working just fine a month ago, had a power outage and did its job. I went to start/run the gen 3 weeks later, know AC voltage on the gauge. The interrupter switch did light at this time. Finally got to work on it today. Found ground wire burnt thru for terminal #9, TB4 bridge. Replaced wire. Did not see any other wiring damage. Still inop. Pull K1 and clean and tap. Still inop. K1 looked brand new inside. Loosened and tightened as many connections I could get to. Still inop. Now the ac interrupter light does not come on. Push test and bulb is good. I did test ground #9 TB4 to all other grounds and is good. I need a direction. I can not find any help in these manuals for this problem. I thank you for any thoughts. Rich

Do you have power at the gauges (voltage and hertz registering) as well as AC at the convenience outlet?

The hertz gauge is working and set at 60. Everything is working properly except the AC output. It was a month ago, it powered the house for 7 hours without issue. As for the convenience outlet, NO. Nothing on the voltage gauge. I tried cycling all the switches many times. I replaced the burnt ground wire and checked it to all other grounds on the gen., even to the grounding rod. One new thing, the light that comes on for the AC interrupter switch no longer light when switched. It lights when you test it. As said I did take K1 out, cleaned it but it was in great condition, as for corrosion (none). It also has the modified fuse for the quad and the varistor. I even tried a new varistor for the heck of it. The fuse for the quad is good. If I remember it is a time reset fuse. So thats what I have for now. Rich

I don't see mention of this in any of above responses... has this unit ever been mouse/critter proofed?

Just wondering if perhaps there is a chewed wire somewhere? Critters love the cozy insides of generators.
