GENERAL INFORMATION
BATTERY
An MSD Power Grid 7 Ignition Control will operate on any negative ground, 12 volt electrical system
with a distributor. The MSD can be used with 18 volt batteries and can withstand a momentary 24
volts in case of jump starts. The Ignitions will deliver full voltage with a supply of 10 - 18 volts and
will operate with a supply voltage as low as five volts.
If your application does not use an alternator, allow at least 15 amp/hour for every half hour of operation.
If the engine is cranked with the same battery or other accessories such as an electric fuel or water
pump, the amp/hour rating should be higher.
COILS
It is recommended to use either the Pro Power HVC, PN 8251, or Pro Power HVC II, PN 8261. If you
