Hi guys I'm sure this has been covered a few times already but I couldn't find anything on the search. Anyway I am trying to get an aftermarket radio to work in my 1990 GQ patrol I have "T" into both the battery and acc cables beside the factory convertor on passengers side panel and ran 2 cables into my own 24v-12v converter but the problem is that when I connect it up it works but as soon as its put under load e.g. listen to the radio or plug in my phone to listen to music it just turns on and off all the time and its driving me crazy! The annoying thing is I'm an electrician and I can't get this to work! Any help would be greatly appreciated
