Electronic Distributor Tech update and a new distributor cap option
A couple of new technical issues. We had the first failure of an
electronic part in one of the electronic distributors. After several thousand miles
of use, the owner was working on the carburetors and the throttle linkage
stuck at a high idle. Instead of turning off the ignition key, he just
pulled off the three connector distributor feed cable, disconnecting the power,
ground and coil signal circuits. The engine, of course, stopped. After
fixing the linkage and plugging it back in, the car started and ran for a
distance, but later died and wouldn’t start. A component on the internal signal
board had failed (It looked “cooked” to me). We replaced the module and
the car is working fine.
When I later discussed the failure with the manufacturer, he mentioned
that there had been another module failure – not in a Corvair distributor, but
in one using the same electronic module. The ignition had been left on
overnight, without the engine running. At that point the battery had run down.
He didn’t specify the actual failure, but again the module replacement
solved the issue. So, now, I guess, I recommend NOT pulling the main
connection plug to stop the motor. If you have to do something in the engine
compartment to quickly kill the motor, pull the coil wire! (Although I don’t like
that solution much either.) Second – Don’t leave your ignition on
overnight. <duh!> It doesn’t seem to be the amount of time that the module was
energized, more like the drop in voltage that caused the issue.
On a lighter note - I am pleased to announce a new option for the
distributor, a bright Blue colored HEI-style distributor cap. I should have these
in stock this week. They are identical to the red/black pin-type cap, except
for the Blue color. I have Blue HEI wire sets available to match the caps
as well. Pricing is the same as the other HEI caps.
