Re: HEI Dist
I've seen plenty of sliced-in copper wire (to replace the original resistance wire) develop a bad connection. The old brass terminals don't accept solder very well. You may have an intermittant 12V connection at the IGN wire on the firewall bulkhead connector. Could be coincidental that changing the module makes it work. It could be that a heat cycle follwed by a zap of electricity when you fire it up the next time is really what's making it work...temporarily.
Next time it acts up, put a volt meter on the IGN power lead of the distributor. Disconnected it'll probably show 12V but when loaded by the distributor or a test lamp it may be dropping to zero volts.
