Re: Still have current when ignition is off

The negative post of most alternators that are isolated are  with a plastic looking washer. Check the continuity with all wire removeds from the negative post of the alternator to the alternator body.

Exactly as I thought might be true. Someone has worked on an isolated component.


I believe that you will find that Amel insulated the alternator from its mounts, therefore isolating it mechanically from the engine. It is highly probable the person mounting the new alternator either did not know about this or ignored it. Check to see if there is continuity between the alternator chassis and the engine block.
