Something not right. If light is same brightness should have enough current the power solenoid.
If you connect wire from batt+ to small terminal on solenoid engine cranks over at proper speed (y/n)
Remove trigger wire from solenoid and connect meter from batt- to trigger wire and turn key to start. What is the potential voltage measured?
Reattach trigger wire to solenoid. Connect meter to batt- and trigger wire connection at solenoid. Turn key to start. What is measured voltage?
Move meter to batt + and trigger wire connection at solenoid. Turn key to start. What is the circuit voltage measured?
Thanks for the reply. The solenoid is made onto the starter and the entire starter is grounded directly to the battery with a big wire, 4 guage or whatever is used on mowers. Also have replaced the solenoid with the same problem. I believe the solenoid grounds through the starter when you bolt it all togetherTo me that sounds like a bad ground on the solenoid. If you have a four terminal solenoid, figure out which of the small terminals is going to ground and either replace it, or make sure the end which is attached to the frame is clean and tight.
