Wiley Farm Posted September 27, 2011 Share Posted September 27, 2011 I want to hook up a CB radio in my 1960 B61. It is still 24v start, 12v run. It still is + ground. Is there any way to hook up this radio without changing over to - ground? Thanks for any help.

I've seen polarity changing boxes in the aftermarket but cannot remember a vendor. Might do a google search for such.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

b61fred Posted September 28, 2011 Share Posted September 28, 2011 HI, My CB has a power and ground wire, I just hooked mine up with the black wire (-) to the power on the truck and red (+) to the dash. Made sure to keep the radio isolated from the dash. Worked so far Quote 15 gears...no waiting!

fxfymn Posted September 28, 2011 Share Posted September 28, 2011 Another alternative would be to create a negative ground power box for use in the cab. All you need to do is to isolate it electrically from the truck by running wires directly to the power source as Fred recommends in the previous post. You could place cigarette lighter outlets that are negative ground in the box that would allow you to use devices such as GPS receivers or phone chargers as well as the radio hook up.I would create an isolated ground bar in the box with a wire running directly to the negative battery post and an isolated positive power strip powered by a direct wire to the positive battery post. Just make sure you protect the circuit at the battery with a fuse or circuit breaker. Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

miro Posted September 28, 2011 Share Posted September 28, 2011 You can use a - ground radio just make sure it's insulated from the truck itself, and make sure the speakers have two wires running to them and are not grounded.

vanscottbuilders Posted September 28, 2011 Share Posted September 28, 2011 You have some good, simple solutions in these replies.Just in case you aren't comfortable doing these things yourself (like me),consider Radio Shack or an electronics hobbyist vendor. I know Radio Shackused to handle polarity reversing boxes - not sure if they still do or not.Paul Van Scott Quote Link to comment https://www.bigmacktrucks.com/topic/20786-b61-wiring/#findComment-87112 Share on other sites More sharing options...
