No spark- what am I missing?
It's been a while since I've had to troubleshoot a points system, but I did manage to get my 67 318 running a few months ago.
This time it's an unmolested 67 225 and it's kicking my ***!
The points were worn to the backing metal, so I replaced them and the condenser with new units out of the box.
Also replaced rotor.
The cap doesn't look bad, and I scraped the tower contacts with my fingernail to clear any corrosion.
I set the gap at .020 (middle of spec of .017-.023). Dwell read 8-10* on my meter.
I have 12v at the coil, and I've swapped out the coil twice, the last time from a running vehicle.
Also swapped out the coil wire twice, last time known good.
I have an adjustable gap type spark checker, and no matter what- no spark.
I could jump/replace the ballast, but if it were bad, wouldn't it start then stop when they key was released?
I thought about jumping the coil to hot, but I've got 12V there.
If I put the coil wire on the spark plug checker, should I get a spark? I got nuthin".
...and that's after three coils, the last one known good!
Seems like something is causing the distributor to fail at telling the coil to fire.
I'm about stumped.
