lincoln ranger 8 troubleshooting

I have a Ranger 8 that has been sitting in enclosed building for several months.
it was working fine when I took it off old truck for storage. Well board went
out in one I was using and had to put this one on truck and it only wants to put
out small amount of voltage now. could brushes be dirty from moisture from just
sitting. Everything else shows circuits are good and no burnt wires with
meter.With grinder plugged in it turns real slowly and with light plugged in it
is very dim. Machine idles up and down as usual but no full power. All help
would be appreciated.

Did you try to start it from a dead battery with a battery charger/car jumper?

Yes I think they did before I got back to shop because I went after new battery and oil and filter to service unit before I started using it again.

I once had a Trailblazer with symptoms similar to yours. It was caused by excess voltage when trying to jump a dead battery.
