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.
