Circuit Resistance Test
- Disconnect ignition coil secondary wire from distributor cap and connect jumper wire between coil wire and ground. Using a voltmeter, connect positive voltmeter lead to negative battery post and negative lead to battery cable clamp.
- Crank engine and observe voltmeter reading. Repeat procedure on positive battery cable. If voltage is detected, correct poor connection between battery cable clamp and battery post. Repeat test.
- Connect voltmeter positive lead to negative battery post and negative lead to battery cable connection on engine block. Crank engine and observe voltmeter reading.
- If voltmeter reads more than .2 volt, correct poor connection at battery ground cable attaching point. If voltage still reads more than .2 volt, replace ground cable.
- Remove starter heat shield (if equipped) to gain access to starter solenoid connections. Connect positive voltmeter lead to starter housing and negative lead to negative battery post.
- Crank engine and observe voltmeter reading. If voltage reads more than .2 volt, correct poor starter to engine ground connection.
- Connect positive voltmeter lead to positive battery post and negative lead to battery cable terminal on starter solenoid. Crank engine and observe voltmeter reading.
- If voltage reads more than .2 volt, correct poor battery cable to solenoid connection. If reading is still more than .2 volt, replace positive battery cable.
- If excessive resistance is not found in circuits being tested, remove starter and proceed to BENCH TESTING in this article.
