Re: destroyed ignition rotor, Bosch Spider

Dean,
I have seen this happen with extremely high resistance in the spark plug
wires.  Especially with a super "weed burning" coil in the system.
I have seen the HEI system on a GM vehicle burn a hole thru the top of the
rotor and go to ground at the distributor shaft.
I would measure the resistance on a known good set of wires and compare that
to what you have.

Subject: destroyed ignition rotor, Bosch Spider

Hi Group:

>snip>Last night I removed the distributor cap from my '87 Spider, to allow
easier access to the coolant bypass hose, which I was replacing.  I was
amazed to see that the ignition rotor, actually the end of the rotor that
the spark jumps from, was burned down to barely a nub.
Any educated guesses as to what happened here?  <snip<
