Stobe light ground wire getting hot!

i have installed a strobe wire system in my car. the directions say to take the red wire and connect it to a switch and then to my car battery and take the black wire, ground it to the car's chassis. i have done that and it didnt work so i ran a black wire from my battery's negative side and connected it to the other side of the switch. now when the switch is in the on position everything is working fine. but when i switch it to of and the lights go out, the ground or negative wire gets hot. i know there is a way to make this work where i can transfer the energy coming from the battery while the strobes arent on....need help with this desperately dont want my car to catch fire

Sounds like you have a short, along with wrong gauge of wire. You need a fuse on the Positive side, and if you did not do it during the install, you are looking at a Firestarter.

So you are saying you have the negative AND the positive connected to the switch???

I would keep a fire extinguisher handy if I were you.

I love your answer Pete. You beat me to it.

Re-read the instructions. How many terminals on the switch?? If there are 2, then the load (your lights) should be on one term, and the battery (running through a proper size fuse) on the other. Re-read the instructions. If there are 3 terms, re-read the instructions. Some 3 term switches require a ground hookup to illuminate the bulb inside the switch itself, to show you the switch is on. Re-read the instructions.
