I add a fuse to the radio and it blows it as soon as I install the fuse

Hi IM AL the owner of Big As Auto Repair!

First, if you don't have a test light then go to a parts store and buy one. Next Step: clip it to the negative side of the battery post, next use the probe end of the test light and check both sides of the fuse with the key in the on position. If both side's light up the fuse is good, if one side doesn't light replace the fuse. NOTE: If the fuse blows as soon as you install it, then most likely the motor is shorted and blowing the fuse, in this case replace the motor. Hope this helps and please visit my auto-repair-website: http://www.bigasautorepair.com/

Easiest to replace would be the factory Delco AM/FM CD...plug in to existing terminals. If wires cut, you should include the plug in terminals with the replacement radio...Local Pic-A-Part is my go to salvage yard radio $25-$75...Walmart also sells radio wire install kits...$14.95? Hope this helps.

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of all the times I fixed the chipper in these 4 years

problem could be radio.10 amp fuse for ignition switch power up radio display the 30 amp fuse for radio amp system in which that circuit hot at all times.

What is the circuit in question powering? There is more than just a radio, there may be amps, antennas, clocks, and lights in the radio that is a separate circuit. Look close at the wiring diagram and make sure none of those things apply. For example, if the antenna gets power from the radio, but is fed from another fuse, there is the tie. Or speed sensing control, ties to the speed control and feeds through the radio. Things can get complicated. You may also have a shorted or miss wired device. If anyone has changed the wiring or components from factory, I would suspect that first.

Hello! Identify which fuse is blowing...also, does it blow as soon as it is installed or does it blow when you turn the key? Lastly your not referring to a fusible link but a maxi-fuse...ie...40; Correct?

check the swr's probably are high if it blows fuse. those should have a 5 amp fuse.

unplug radio if proper fuse don't blow it's in the radio or the way it's wired

If the red wire scraped against the firewall on the way to battery due to sharp edges on the metal it will just short out. It has a dead short somewhere in the wiring or in the CB itself thats why it is just popping fuses as soon as they are installed.

something loose in the wireing when driving .the wires are grounding out
