I'm still driving around my 3.2 conversion in shakedown mode. After the first drive at night I thought I noticed that when I flicked on the high beams the engine cut-out for an instant. I spent a little time debugging the problem last Sunday and found that 30% of the time when I flicked the high/low beam switch on the column the engine would cut out for an instant. It didn't matter whether the switch was going from high to low or vice versa. 30% of the time the engine would cut-out. I pulled the hi/lo beam relay and disassembled it, touched up the contacts with a die makers file, cleaned it with electrical contact cleaner, blew it out and re-assembled it. When I re-tested the relay by flicking the headlight between hi/lo beam the engine now cut-out 100% of the time! I thought that was pretty interesting and went in and ordered a new relay from Pelican. Tonight I put the new relay in and the problem is completely gone as expected. I can't wait to find out if that was also the cause of a day-time "miss" that's been kinda coming and going...
These old cars never cease to entertain me with bizzare symptoms and surprising causes.
Later,
Kevin
The old relay...
