Scott,
I would suspect the regulator in your alternator, should show 13 - 14 volts on
the meter. At the end of last season I noticed my readings at 11 - 12 volts
and finally had to jump start the car to get running. I also noticed I was
breaking up at the upper end of my power range ( 6800 - 7000 rpms on fast
street cam ). I had the alternator tested and found to be bad so I replaced
the regulator and all seems to be running well
Car has 1500 engine but not built to full race specs, its being use for
autocrossing.
Best of Luck,

Subject: [Fot] Low voltage miss?
I'm currently using a distributor with a Pertronix II Ignitor in it. A
ouple of weekends ago at Blackhawk Farms, the engine developed a miss
t 7,000 revs - wouldn't pull beyond 7,000. This is a Spitfire 1296
mall-journal motor with Kas' A-10-A cam in it, so I could use some revs
eyond 7,000.
The battery voltage was low all day - something in the neighborhood of
2 volts. Would voltage at that level cause a Pertronix not to work
roperly? Seems to me that should be enough volts to make it work fine.
The alternator seemed to be putting out plenty of charge, but the
attery didn't seem to improve through the day. That was the first race
f the year, so I've pulled the battery and given it a full charge off
he charger. Will see how well that works out, but may need a new
attery, too. This one's 4 years old now.
If that doesn't help, I'll have to send my distributor off for testing.
Anyway, just wanting to make sure my sparks are in order before I go
essing with the farging carburetors...
Scott
