Hi,
I'd like to thank everyone for their kind and considerate replies in regards
to the charging problem on my TD. With the generator isolated I have less
than a volt on it, which is pretty definitive.
Some time this week I'll take it off the car and go over it on the workbench
and see what can be done.
Thank everyone again,
Scott Allen

Hi Scott,
You may not need to flash the generator, but it's something that is
easy and does no harm.
Checking the wires at the regulator tells you condition of both gen
and wires. At the gen, it tests gen only. You can do whichever is easier
for you as it's unlikely that the wires have perished.
For polarity, you would ground to Pos if the car is still earthed as
it was built ( Pos earth) If it has been changed to Neg earth, then
ground the voltmeter to the neg wire. Voltmeter should show the voltage
either way though, pos or neg, but voltage should be indicated.
Changing from pos to neg or back to pos is when you do need to flash
the generator. It gens equally well with either polarity, but flashing
tells it which is which.
While you're sleuthing around at this, slide back the cover band on
the dynamo and look at the brushes. They may be worn and not making good
contact. Weak then no charge can be that they were just worn down, then
worn out.
