I have an electrical bug in my 91 Buick Regal. It has a voltmeter.
Whenever I take off from a stop, or if I put on the brakes with the
car stopped and push the gas a little, the voltage drops to 10 volts.
All the fans and lights go dim. Thos problem is driving me mad. I have
consumed 3 alternators in 3 years and can't find it. If I had an
ammeter, like in my TR6, then I could determine whether the alternator
is failing and there is a huge charge draining out of the battery, or
if something was drawing enormous current. The ammeter is more useful
by far. As noted in another posting, the wiring is more complex and
requires more heavy-gauge wire work.
On the Buick side, (sorry about this non-LBC question) has anybody
seen this one? I was sure that it was a connector failure occurring
whenever the motor twisting in the frame at acceleration, but the
damned thing has two top braces and barely quivers when under load. I
am now wondering if the torque-converter locking mechanism is acting
insane. This problem has been going on for years, so if this was a
faulty wire, the currents involved would have fried it long ago.
