Stereo & Electronics - Humount wire problem/fuse keeps popping
I have had my custom Humount installed for a couple months with no problems at all. I wired it up directly to the radio harness so it is always on as long as the key is turned over. I decided I wanted to add a toggle switch so I could turn it on and off during the day. I ran the wires from the mount to a toggle switch and from there to the radio fuse in the fuse box since I knew it would handle the extra no problem. I grounded the wire to a screw on the fire wall. When the toggle is in the off position it immediately blows the fuse when I turn the key. I replaced the fuse moved the toggle switch to on and turned key and the mount came on with no problems. I then switched it off and the fuse blew. I tried putting a higher fuse in and all of them blew the same way. Am I missing something here I am just overlooking??:huh:

is it a switch with 3 prongs and a led that lights or something like that. if so you have 2 wires backwards
No the switch has two wires coming off of it. I ran one red power wire to the fuse box and the other black to ground on the fire wall. I didn't try reverseing them because I didn't think it would work if the polarity was backwards since it turns on? The mount is LED but it only has two standard wires coming off of it.

why are you running a wire to ground this is your problem
Because there are two wires coming off of the mount one for power the other for ground? It won't work unless it is grounded.

The HUMount needs a ground but the switch should not have a wire going to ground. Proper connection of the switch would be:
- a wire from your power source (fuse panel) to one terminal of the switch
- a wire from the other terminal of the switch to the power (red) wire of the LEDs.
- the ground wire (black) for the LEDs is unswitched and goes straight to a chassis ground (not to the switch)
Ahh...Thank you for the help...I will wire it up when I get home today!!!!!
