GeorgeS Posted August 26, 2006 Share #1 Posted August 26, 2006 At the Large White Plug, with the 3 #14 wires comeing from the Alternator: Do the following: Measure the AC voltage on each wire. You can stick the meter probs into the end of the White Plug. ( located just behind left rear cylinder, White connector, with 3 white wires thru it ) With Engine running, you should Read 9 to 15 volts AC, ( thats AC, not DC ) on each wire. If the voltage on " one" wire is substantially , Lower then the other two, then your Alternator is failing. This is a much better way to check it then useing the Resistance reading method given in the Service Manual. Link to comment Share on other sites More sharing options...
