I'm pretty sure the Pertronix needs a solid 12 volts. If you are
discharging with lights on you may not be getting full 12 to the ignition.

Subject: [Tigers] Tiger charging normally until you turn headlights on
Hi all,
I thought I would mention this one to the list, make sure I am going in the
right direction. If I start my tiger and run the RPM's up, My amp meter
shows about a 5 Amp charge (until the battery is charged back up). If I
turn my headlights on (with the RPM's up) it shows about a 3 Amp discharge.
The other interesting side effect is while driving around with the
headlights on, the car cuts out dramatically but momentarily... like the
Pertronix ign module is browning out or something?
Anyway, since it charges at all, I assume that means that the generator
works, and that I should go look at the Voltage regulator first, and if that
checks out, then move on to check the generator. I think I still have a
used spare generator on the shelf. Will the local parts houses even know
how to test those correctly anymore if I bring one down to them.
Its been alot of years since I have had to work on a generator problem, so
thought I would try to do the research on them. I did run across the
comment about polarity/charge on the charging system, especially one that
has sat
around for a while. I had forgotten or never knew that, but since I am
getting charge from my current system, I am more concerned with that on any
generator I might have sitting on the shelf.
Just thought it was odd that a discharge condition would cause the Pertronix
module to brown out occasionally. Wanted to make sure that I shouldn't be
looking at lighting system draw to ensure that don't have something weird
that is actually causing a massive draw and just maxing out the
Generator/regulator.
Thanks,
Steve
