Okay, I think I've calmed down enough to ask for help on this problem
without using any swear words. Basically the problem is this: Last
I replaced my points ignition on my 74 TR6 with a Crane electronic
It seemed to run beautifully, no hesitation and didn't miss once. However
that night, while driving home I noticed that all the lights seemed pretty
dim and that the volt meter was rapidly dropping. The solution was
drive w/o the lights and pray I made it home. With the aid of a little
and a sympathetic policeman, I was able to coast the last few feet into my
Basically when running the car I am not getting any charge into the battery
at all. The voltage across the battery drops when the car is running.
spent the last week trying to figure out what the problem is and can't
figure the damn (oops there I go) thing out. The obvious culprit was the
alternator (lucas 2 wire regulator), but having it rebuilt (twice) didn't
help at all. The Ign light comes on when the key is in the on position, but
goes off as soon as the car is started.

Check your big brown wire. It runs from the alternator output
to the multi-tap on your red battery cable. If this wire is not
making good contact than your Alternator may be working just fine
but the current is not making it to the rest of the electrical system.
And I've seen this before.
If you have a voltmeter, unplug the brown wire from the alternator and
measure the voltage at the tab. Compare it to the battery voltage
with the wire hooked up. Is it the same?
The problem may be (fingers crossed) that the multi-tap (or whatever
it is called) gets corroded (being close to the battery) and current
If this doesn't fix it you just might have to spend some money. ;-(
