Priority Start Battery Protector

A device that disconnects the battery if you leave your lights on, or another drain occurs, and the battery becomes weak. It has enough smarts not to disconnect the battery if you have your hazard lights on or the engine is running. It automatically resets if you open the door, push the brake, or similar.

Installation

Installed without much problem. Good directions come with it. Some additional notes: I suggest that you take out the spare tire and take off the battery hold-down clamp to get decent access to the ground terminal. I had to squeeze the Mazda positive battery terminal with pliers in order for it to get a good grip on the Priority Start terminal. Before you attach the unit with the provided tie wrap, note that the cables will only reach if you put it on the smaller side of the battery (pointing toward the drivers seat). Don't forget the ring on the negative terminal, as I did the first time. Caution: be very careful that you do not provide a short (path) between the terminals of the battery, such as by dropping a conductor (wrench, screwdriver, ...) on them, or by making a conducting pathway from the positive terminal to any point of the car with the negative terminal cable still attached.

Evaluation

After reading a seemingly lukewarm review of Priority Start in Miata Magazine 1997 issue 2, I had my doubts about the effectiveness of this unit. But when I drove along Florida's coast line to Panama City and had lunch in a sea food restaurant in Apalachicola, I left my lights on. When I got back to the car, Priority Start had properly disconnected the battery. I turned off the light switch and started the car with no problems at all. The only thing I had to do was reprogram the radio stations. Beats trying to find a tow truck and waiting an hour or so for it to show up! So, as far as I am concerned, the unit has already earned its cost. In view of the inconvenience of a dead battery and the high cost of replacing the Miata battery, I think the price of Priority Start is acceptable.

Price

$59.95 from the Dealer Alternative 1-800 359-6957.

Update

The Dealer Alternative increased the price to $75. A nice round number, but I do not think it is worth it.
