Barney,
Thanks for the info. I hadn't thought about the regulator but then the
smoke is still fresh. Last time I had a regulator and alternator both go
out was on my '74 Toyota Landcruiser about five or six years ago and I
replaced both the original Japanese parts with reliable Lucas parts (true
story - and they still work, like a charm).
