Can a weak solenoid cause a car to not start?
Although rare, a weak solenoid can allow the starter to spin without engaging the engine’s flywheel or flexplate. In such a scenario, you’ll hear the starter spinning, but the engine won’t crank. It’s possible for high resistance in the starter solenoid to cause the contacts to burn.
What kind of starter wire does a solenoid use?
A typical starter solenoid has one small connector for the starter control wire (the white connector in the photo) and two large terminals: one for the positive battery cable and the other for the thick wire that powers the starter motor itself (see the diagram below).
When does a solenoid need to be replaced?
