i installed an electric fan and now my radio doesnt work, and my car alarm goes off when i put my key in the ignition. when i start the car the alarm stops going off. radio doesnt even turn on. i did get the fan working though. please give me some help. i checked the fuse.
i installed a manual switch. the fan is hooked up to b+ and the negetive fan side is ran to the switch and a wirecome out of the switch and goes to a good ground.
if the switch is on the hot side there will be a small spark every time you want to turn on the fan. but there is no spark on the negitive side. its is for the same reason that you disconnect the negitive side of the battery first then the positive side.
