Frank,
Something similar happened to my TR4 a few years back.
I was driving with my future son in law down the highway and we got it up to
70 and I noticed the amp-meter pegged 30+.
I have never seen that before, usually when they go, it was - whatever the
system was drawing on the battery.
When we got hope about 10 minutes later, I popped the hood and tried to test
the connections on the generator and it was too hot to touch. I figured it was
fried so I waited and swapped in a spare.
The car has run just fine since that time. No problems when lights are on,
wipers etc.
I took the faulty generator apart and noticed that the solder in the
computator (sp) was all melted and it had shorted out.
I used the Lucas diagnostic manual sent to me by Randall to detect a short
somewhere which caused the high + reading.
I don't know what was the original cause. As far as I know, the only
electrical component that was operating at the time was the coil and gas tank
sensor.
