Outer Limits 4x4 Board

i was just rewiring my uhf power, and i acidentally put the black to red, the 2a fuse in the line blew (i dont know how long it took), so i resoldered it back the right way, and now she no work just connecting the wires together to bypass fuse, did i farnarkle it?

its a gme tx3200

Sounds fubar.

OOPTH!!!!!!!!! i forgot which circuit i had it wired into, i thought it was piggy backed off the stereo, but it was off the cigarette lighter, neways, ended up that it was just the main fuse for that circuit had blown as well.

And the award for the over use of forum comeback pics in one thread goes toooo


Bogged.


Not Funnay.

they have a ....(cant think of the exact name of it but its something like a ) "polarity diode", I did one a few years ago in a 24volt truck..... every other wire in the dash was 12volt BUT the one I picked....

cost $50 for a local tec (next town along) to fix it of which $12.00 was postage/packaging & insurance.

Yep they have a protection diode in them. Most of the time the unit will still work even after its poped. But they can be repaired.....

All it is, is a reverse polarity diode across the power wires. When connected properly, the diode does nothing. If you connect the wires wrong, the diode causes a short circuit blowing the fuse. That way all the power goes through the diode (easiest route) so the rest of the radio survives.

Moral to the story: ALWAYS have a seperate fuse inline with your CB

Note: According to Murphy's Law, a $300 picture tube will blow first to save a 10c fuse!!!
