I have inquired a B&S motor on a log splitter. I believe the motor to be in good shape mechanically but there are some doubts electrically. I am not receiving a spark. I need to know what is involved in this. I know about the magnet on the flywheel creating voltage within the coil but there is a wire coming off of the coil to a ground lug and along with it is a wire that leads to another small box mounted on the side of the motor. There is another lead coming out of that box that went to a switch and the wire coming out of the other end of the switch went to a mounting bracket. Is this just a ground loop for a shut off? Please assist. email to pgapew@hotmail.com

the extra wire goes to a low oil shutoff switch. This switch goes bad frequently. diconnect wire from the oil shut off switch and test for fire again.

The small wire coming off the coil is the kill wire.
If it's grounding out the coil will not produce spark.
