do a ground side voltage drop between the solenoid housing and B- , may find a bad ground connection somewhere?
So exactly how do I do this? You'll have to spell it out for me.
Same way you do a voltage drop on the + side... Perhaps review the briggs training? if I recall,they did have details on how to voltage drop the ground side too.
Meter on volts scale,one lead on the Solenoid ground side (if it is 2-pole primary,if there's just 1 primary,then solenoid body is the ground path) and one lead on the B- post , crank engine and observe voltage reading. a perfect connection will give 0 volts , anything above 0.1v or so and you have a ground resistance. Repeat test by moving the test lead from solenoid ground to the next point at which the ground goes to- Wire connector,or in the case of body grounded solenoid, to starter body or engine block (trace the ground path of the solenoid) until you show below 0.1v - once you find a spot that does that you have isolated the resistance between the 2 points that show the voltage difference.
It's basic electronics theory dealing with Ohms law.
