(This is in response to another thread, but also posted as a new thread to hopefully increase feedback)
1) generac (Model 43093 LP) died during Irene...
2) Now it does the 15 second run, then off, then on for 7, etc.
3) Had fuel pressure checked and looks fine.
Performed test #70 and run winding voltage was non-existent, or very low.
Performed test #6, and got ~11.5 volts.
I tried flashing the field (#4 wire removed from J1-1 and jumped to battery 12V), and did see an increase in run winding voltage output. However, the VR LED never came on.
#1) I am not sure which model this is.
#2) I am not sure what problem you are having - 15 second run? or 15 second crank?
#3) Depending on your problem, the flowcharts in the diagnostic manual are there for a reason. If you are going to try and diagnose / repair yourself, then you are best served to follow the tests outlined in the flowcharts. If you skip around and do some random tests based on what you think sounds like the problem, you will end up just chasing rabbits.
