Battery disconnect switch.

Hello. I installed a cheap Pico battery disconnect switch and THEN I read the instructions. It is installed in the middle of the battery ground cable. The instruction say "Do not install switch on vehicles with full time power demand computers or vehicles with thermostatic controlled electric cooling fans. I don't have any computer but I do have the electric fan. Can anyone tell me why? I tried getting in touch with Pico but that did not work out. Does anyone know of a disconnect switch I can use that will work with the fan? Thank you.

It'll work just fine....... when you disconnect the battery and reconnect you place a surge on some computer controlled circuits...... I've had a disconnect on my BMW, with lots of computer stuff, for 5 plus years now.... no ill effects and no dead battery for a seldom driven car. BTW Adv auto sells a very good disconnect for 12 bucks.

Your cheap Pico disconnect switch simply needs a fused by-pass.

That fuse will pop like a flashbulb if you forget to reconnect before cranking though.

Sometimes electric fans and the temperature control relay are wired to the "always-hot" part of the electrical system because they can run after the engine is shut off.
IMO it serves no purpose to run the fan when the engine not running because the coolant is not circulating.
