NAPA also stocks them, but at a considerable price markup over buying direct. Snyders (the Ford guys) listed them in 2006 at $20 each, no doubt more now if still the same switch.

PS - just browsed the Cole-Hersee website catalog for battery disconnect switches, and there are many of them. The heaviest duty one I saw, model #75908 single pole, is rated at 2000 amps intermittent duty.

PS - they also have quite an assortment of other electrical auto switches, headlight & foglite switches, brake light switches, dimmer switches, and many more.

Thanks for all of the replies and interest.

I took her out for a 30-40 minute spin tonight and then re-tightened all of the connections when I got home, while everything was still warm. I seemed to work fine and no parts were overly hot.

I still think the Battery Brain was designed for positive ground. As an example, the main switch mounts on the positive terminal with a small lead going to the negitive (to complete the circuit for the switch?) Any tampering is supposed to cut the switch off as a theft deterrent. But on my set up (with positive ground) if I removed the small lead, the switch stayed on, rather the turning off.

I really like the Cole-Hersee battery switches, they still make things the old-fashioned way, rugged as can be. We used their battery switches in the collection I worked at, we had dozens of their switches in use and never so much as a problem. I worry that one day someone at Cole-Hersee will die, the business will be sold and some business school prick will take over and that will be the end of it. I hope I'm wrong.
