Starter Solenoid

Up

 

Well, I began having a weird problem...

Sometimes, it was difficult to make the engine crank,  so, I quickly checked the voltage at the starter solenoid terminal with the ignition key in Start position.  It was like 8.50 volts...   so, I tought, I have voltage...    the starter solenoid is defective...

I changed it, and the problem was still there...  

The problem was that the 8.5 volts were not enough to activate the starter solenoid.  So I installed and auxiliary solenoid.

The ignition key energizes the auxiliary solenoid  which in turn activates the starter solenoid.

 

This problem is quite comon among Cavaliers and this is a solution pretty simple and cheap.   :)

 

Installing it...

Installed...
