Re: Battery Cut-off switches

HH: Most of the problems I had (my opinion) was because the switch is set up for negative ground use. With a positive ground car, the switch works opposite as it should. I have had to call them 4 times so far for advise. To keep the car running under a load (generator system, not alternator) I had to buy the engine vibration sensor at an extra price. This has worked good so far.

I tried to clean the battery after it was installed with baking soda and lots of water. The connections would not work wet and I had to dry everything up before it worked properly again. Finally, because of the polarity issue, if you disconnected any connection, the switch stays on, rather then shuts off, as a thief deterrent.

The last time I called Battery Brain direct, I suggested that it might work better on the negative post, but the tech. said that their switch needs to be on the positive terminal to get power.

Again, I can shut the battery off as soon as I pull into my attached garage for safety and I don't have to raise the hood as the switch is on the key fob.
