Asad,
I'm not an electrician but I agree that positive from BOTH the DF and D+
does not sound correct. I believe that when you flash a generator to make
certain the polarity is coprrect you connect the positive and negative
terminals of the battery to the generator termonals. Getting +15 volts from
both terminals just doesn't sound correct and that may also be what is
causing his generator to become so hot.

Subject: [vintagvw] 69 Bug generator probs.
Hi all,
Again asking a question for a friend. He has a 69 bug which he is
converting to a buggy. Had charging issues. Got a lot of bad advice from
local mechanics and electricians. Ended up getting his generator rewound.
Now what he posts to me:
Quote:
''Well the problem is ... With No Connections and running engine, I am
having +15(Varying) voltages on DF terminal of my dynmo, and -15(varying)
voltages on D+ terminal of my dynmo.It should give +15(varying) voltages on
both D+ and DF terminals.Any guys having same kind of dynmo can solve this
issue for me, all they need to do it, temporarily disconnect DF and D+
terminals from their dynmo and use VoltMeter to check voltages on DF and D+
terminals while engine is running.Also to check what degree the dynmo heats
up with connection and without connection to cutout and related
assembly.Hopefully these checks and tests help me to resolve my isssue.''
End quote.
Second prob he was facing is that the gen heats up to the point that
he cannot keep his hand on the housing for longer than 5 secs. What could
be the issue apart from what I asked him to check, namely:
1.Worn gen bearings.
2.Missing cooling plate in the fan housing.
3.Maybe its due to the fact that the gen is not connected to the wiring???
Havent spoken to him since he sent me the above text but I think I
dont agree with the getting positive voltage at both D+ and DF terminals.
I did advise him to get an opinion from the person who had rewound the
gen.
Any help would be appreciated.
Asad.
