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.
