Genrac Inpact 36 lp - Sleepy Help
I have looked at prior threads - in particular Sleepy's comments back in 2009. Hopefully I'll catch him in a good mood... 1. Generator ran fine last weekend - but battery was weak so I replaced it...

Link toThread where I found my starting issues-failure of the board relay that sends power to energize the starter contactor (starter solenoid). But simple board failure-not from reverse polarity connection.
There are many test you can perform to identify problem -most however depending on generator install require removal to access. However a few simple ones may help.
1. To verify that starter motor is OK, simply jump the 2 large terminals on starter contactor. (It sets behind the lil square box.) One is the battery cable the other goes directly to starter motor. It wont start but should turn. You could use battery jumper cable and make contact outside gen.
2. If motor turns when power applied check the contactor. Run a small hot 12v lead, jumper wire from battery and touch the small terminal at bottom of contactor that BLUE wire is connected to/
This energizes the contactor (solenoid) and sends power to starter. If it doesn't turn but turns with step 1, its likely the contactors coil is burnt. If contacto clicks though could be contacts inside contactor. (you can fix if coil OK) or fairly inexpensive to replace.
If starter does turn when manually energized then out put from board (blue wire) needs to be checked. should be a constant 12v when start button engaged after 2/3 seconds. (unplug wires to gas solenoid which is activated when start button pushed, probably click your hearing)check voltage at blue wire terminal of contactor. If no power or rapidly fluctuating then its board out put.
Its a start, at least to eliminate something. I'm trying to picture reverse polarity--I cant see how it would affect starter or solenoid though. but might be lucky well-boards aren't cheap.

Board is accessed by removing the switch panel and other tins. Its mounted vertical beside fan
