Mitsubishi Repair: 1995 Mirage, ground terminal, ohmmeter


Question
The car that I am working on is not getting any spark. Ive found that the coil has resistance across all three terminals and coil tower. should the ground terminal have resistance also?

Answer
Hi Patrick

Try this,
To check a wire in a harness you connect one lead at one end of the wire and the other lead to the other end of the wire. If the wire is good you will get a reading. If it is broken, you will get an infinite reading. This is useful in determining why a particular component is not getting power. Just be sure you isolate the wire from the circuit so your ohmmeter does not get damaged
