So, on my 67.5 it was not charging very well. The battery would last a few
days then start to go down hill. I replaced the regulator and drove it a few
miles. I picked up my daughter and on the way back the amp gage went to about
15 amps charging, cool! As this happened, the Roadster started getting a
bad miss. I pulled over thinking something came loose. Found nothing and
eventually unplugged the alternator and it ran great.
This weekend I put on a one wire GM alt my son had a new Powermaster unit.
Same thing...... Plugged in the car has a bad miss, unplugged it runs great.
I have gone through and cleaned the plug from the starter (that powers my
ignition), reworked my ground cables (stock locations battery, block, frame,
body), replaced the wire from the reastat to coil which was just holding on by
2 strands,,,,,,, Every time I make something better it misses worse. Now
with the alternator plugged in, it misses bad even back-firing through the
carbs. Unplugged runs great.
I an going to check the voltage at the coil, but I did not have help and cant
keep it running with the alt plugged in.
Ideas????
