[QUOTE="hillrancher, post: 474460, member: 6761"] Should have your volt meter set to the next higher setting than the voltage you are testing to protect the meter, but since this is 12v DC set at 12v is ok. You should not get a reading with every thing turned off. If you are getting a reading you have a problem then start isolating, by pulling fuses. The white wire is the exciter wire for the alternator I am thinking. It should have a light in it for a resistance which is on the dash to show if the alternator is working. This white wire kick in the regulator. Do you have an external regulator or internal? [/QUOTE]
