need HELP: alternator problem

Sun Feb 18 10:09:49 EST 2001

Yes. I actually don't know at what point the dash voltmeter is connected. If
it measures voltage on battery (not at alternatore as I thought ) then it
might be a problem. And I had already some signs in the past  that that
connections is intermittent. Unfortunately I need to replace MC on my 'new'
200tqw and bring it home form PO place today. Then I will return to alt.
problem.
Thanks.
