I've been playing with my Onan 6K a bit.
It was stuck so I pulled the head and pushed it free and cleaned it up, it looks to be in good shape inside.
Once I got it turning over i have found that I have no spark.

Breaker points seem to be working, didn't try to measure voltage there, what should it be?

I haven't been able to make any sense of the troubleshooting guides so I was hoping you guys have some suggestions for me to try?
Oil level is a bit low, would the oil sensor cut the spark?
Looking at the board, it seems to be in good shape, no blown resistors or caps etc.

Tried to measure resistance of the coil, and couldn't get anything but infinity. (put positive lead in the plug wire hole and put negative on the ground bolt on the top of the coil)

Any ideas?
