Priority Start is the only automatic computerized on/off protection system for your Corvette battery, alternator and electrical system on the market today. If battery voltage drains below 11.7 volts when the engine is off, it automatically disconnects the load, leaving starting power. The 12v PromaxHD is recommended for vehicles with increased electrical/load demands.
To reconnect and start: Simply step on the brake pedal, activate headlights or operate any other accessory and starting power is reconnected. It’s positive to positive with a ground wire and you’re done.
Universal design fits top and side post batteries. No hardwiring or modifications required. Transferable. Manufactured to ISO, USCG and SAE standards.
Electrical components are Non-Returnable Parts.
Always refer to a factory service manual when diagnosing engine service problems. You can damage electrical components if the proper procedures are not followed. Be sure you are replacing the correct part.
