Wouldn't I need to run another ground wire as well to make this test
worthwhile? I understand that sometimes, there can be an intermittent
ground that could cause the same symptoms as an intermittent power feed.
Where would you run it from/to? I'm horrible with electrics...I once (in
the not-so-distant past) blew up an alternator because I put the battery
leads on backwards!
I'll be sure to at least make a message to the list regarding the outcome
of the whole situation.
Regards,
