I've cleaned the terminals at the battery and engine. I have just replaced the starter.
My car has 160000 miles.
My car has a manual transmission.
Check the wiring with a digital volt and ohm meter with resistance and see how much resistance is on the ground wire that you have found that is bad. If the resistance is high, then there is a connection that is causing the wire to have a high resistance. If the meter reads OL, then there is a break in the wiring and the wiring harness or wire would need replaced or repaired. If you need further assistance with your electrical wiring, then seek out a professional, such as one from Your Mechanic, to help you.
