The Stovebolt Site Forums The Shop Area The Electrical Bay posessed radio (in need of excorcism?)

I've got a new Sony radio hooked up in my 57' GMC which has worked fine until recently. The strangest thing is that once the motor RPM's reach a certain level, the radio loses power. Once the RPM's come back down, the radio pops back on. The power wire to my radio is connected directly to my "kill" switch which is also connected to the ignition. I can't understand why the radio would be effected by RPM's? It is not vibration, ....I am convinced it is electrical. Thanks for any advice you can give! The rest of my elctrical system is perfectly fine. It is 12V. :mad:

Your voltage regulator is either fried or set too high. Most new radios shut off if the voltage gets too high. Check to make sure that the voltage never goes above 14.

Megga dittos. I used to install those buggers for a living. You must be crankin out some serious voltage to make her shut off.

Yep...sounds like a little to much juice. Sometimes it works best to power accessories directly off of the battery. You will likely has less voltage spikes and power variences.Try adding an accessory terminal block powered by the battery. The adding even more accessories will become much easier in the future. Most solid state accessories don't like voltage spikes, it causes smoke to leak out of 'em. The battery will asorb those so you will have much happier and longer living accessories..... Randy

It could be the flugal valve! :p

Flugal valve? Thats right next to the radiator on a VW bug, isn't it?
