OhareFred Posted May 27, 2015 Report Share Posted May 27, 2015 Try resetting radio dis disconnecting positive battery cable for 30 mins. Worked for others. You can disconnect it at the jump point. jkeaton 1 Quote Link to comment Share on other sites More sharing options...
dhh3 Posted May 27, 2015 Report Share Posted May 27, 2015 NO. Disconnect the negative terminal for at least 30 minutes for radio issues. If you disconnect the positive terminal, you run the risk of frying all of your electronics! Quote Link to comment Share on other sites More sharing options...
bramfrank Posted May 27, 2015 Report Share Posted May 27, 2015 It shouldn't make a difference which battery terminal you disconnect, so long as the vehicle isn't running when you disconnect it. Quote Link to comment Share on other sites More sharing options...
Lobitz68 Posted May 28, 2015 Report Share Posted May 28, 2015 I've always been told negative as well... disconnected the positive once as a youngin and the sparks were flying... Seems like it may be easier to accidentally mess something up that way. Quote Link to comment Share on other sites More sharing options...
dhh3 Posted May 28, 2015 Report Share Posted May 28, 2015 You touch that positive cable to anything metal and your car is dead! Quote Link to comment Share on other sites More sharing options...
bigtsr Posted May 28, 2015 Report Share Posted May 28, 2015 The reasoning is that the vehicle is negative grounded , if your wrench hits bare metal undoing the NEG no big deal while undoing positive is a dead short across the battery source and who knows what you'll screw up along with the sparks. dhh3 1 Quote Link to comment Share on other sites More sharing options...
rolly Posted May 28, 2015 Report Share Posted May 28, 2015 I agree with all the negative comments. dhh3 1 Quote Link to comment Share on other sites More sharing options...
bramfrank Posted May 28, 2015 Report Share Posted May 28, 2015 Horse manure - if the positive cable isn't connected to the battery and touches the chassis it is no different than if the negative cable is disconnected and touches the battery positive terminal. In the olden days that wanted you to connect the positive lead of a booster cable to the battery positive and the negative to the chassis ground point as the second point of contact so that any battery fumes floating around the battery wouldn't be ignited by a spark. But the electrons really don't care whether the positive or the negative is disconnected - you end up with the same inrush current when you reconnect things. dhh3 1 Quote Link to comment Share on other sites More sharing options...
rolly Posted May 28, 2015 Report Share Posted May 28, 2015 According to my manual (Bible), you connect the positive first when jumping a car off. To disconnect, you do it the opposite way with negative removed first. So in both instances at one point just the positive is attached. The whole thing reads retarded as hell in the manual. I know we arent jumping the car off, but the same would apply to connecting and disconnecting power to the battery. So logic would dictate removing the negative terminal. ---- Touching the negative to any part of the car is safe because the car is naturally grounded and thus negative. That is why it directly touches the firewall. The positive is protected by a cap because it will short if it touches the sheet metal while the negative is connected. . You're getting a charge out of this, aren't you? dhh3 1 Quote Link to comment Share on other sites More sharing options...

OhareFred Posted May 28, 2015 Report Share Posted May 28, 2015 My thinking when I said remove the positive cable was that the radio has its own ground wire. if the positive is still attached, the radio may not reset because it may ground itself, UNLESS you disconnect at the battery. I said disconnect at the jumping post. I also assumed that it he poster would know not to let the cable touch metal, which was poor judgment on my part! Although, I think just about everyone who's turned a wrench has had the exciting experience of shorting the positive cable/wrench and seeing sparks and didn't blow up the car...lol dhh3 1 Quote Link to comment Share on other sites More sharing options...

I agree that if you take the POS off at the battery the cable touching anything is moot. I was assuming (because of the DJs unique battery placement) that Joe Average would try it at the jumper point hence the wrench in the monkey works. dhh3 1 Quote Link to comment Share on other sites More sharing options...
