Yes mate as you said........Engine running, Battery connection post on the back of alternator and used the alternator casing as the earth.......had 11.9v.Dave999 wrote:
what did you test above?
alternator casing is at 11.9 volts when ruinning?
or you checked between the to-battery stud and earth when it was running and only got 11.9?
if it wasn't running i'd expect that. you are just seeing battery voltage
the ammeter bit is a red herring don't worry about that current takes route of least resistance

At the battery posts (pos to neg) I was seeing mid 12's so that I would assume, even when running, is just the battery on its own.
After I adjusted the idle up a little, the same test above was showing 13.4v at the battery posts.
Spent an hour or so last night wire brushing the battery to body and engine to body ground wire, plus both headlight grounds. Will look at the inside the dash tonight and do the same.
Alternator arriving tomorrow, so will see if that changes anything on top of what I've already done!
