Roadmaster Automatic Battery Disconnect • 766

Product Details

Eliminate the inconvenience and danger of pulling your battery cable. Just connect it and forget it. After the initial installation, the vehicle can be towed and then driven without any further adjustment to the battery. It is ideal for anyone towing a vehicle which must be towed with the battery cable disconnected. It provides a positive current source for breakaway systems or other accessories which must be connected to the battery. Note: the 766 is not for use with diesel engine vehicles. A gasoline engine will typically surge less than 100 amps during starting. Due to the very high compression ratio of diesels, they can surge up to ten times that amount, causing the solenoid to fail.
