Expert Answer

When turning the key to crank the engine, it may just make a click sound or prevent the vehicle from having any power at all.

Question

How can you determine if you need a new solenoid or starter?

Community Answer

Attach the red lead from a test light on the solenoid terminal closest to the starter, then the black lead on the terminal furthest from it. Ask a friend to turn the key in the ignition. If the light comes on, the solenoid is engaging properly and the issue may be the starter itself.

Question

The wire on my solenoid was spliced together and needs to be replace. Can you tell me what gauge wire I need?

Community Answer

You can use eighteen gauge wire in most applications, but refer to the service manual for your vehicle for a more specific answer.

Question

Is the solenoid bad if the starter works after tapping it on an '06 Subaru Outback?

Community Answer

Yes, most likely, the solenoid's internal contacts are worn, and tapping helps make a connection.
