Why does my solenoid keep holding back?
It indicates a situation where the holding coil of the solenoid keeps holding back, mostly as a result of not enough current reaching the solenoid. It can be caused by loose connections or corroded terminals. It can also be a sign of contacts that have welded together, or that have become worn out.
What is a starter solenoid?
