I just bought a 72 charger w/a 360 motor. Anybody know what the spark gap should be. I have autolite plugs if that matters. I also have an 03 RAM 1500with an elctrical problem of some kind. I am not the sharpest tack when it comes to electrical problems so any help would be appreciated. The problem is this. At random times the blinkers don't work, or the left comes on when you click the right one and the other way around. If you turn off the blinker them turn it back on again it usually works correctly until the next time. Also at random times, all the guages will peg out then drop back to normal, or the tach will bump up a 1000 or so rpm's but the engine isn't reving up when it happens just the guage movment. I would think they were different issues but they both started at the same texact time, even they don't always occur at the same time. Any Ideas? Thanks

 

Sounds like a bad ground.

 

plug gap should be .035

 

Rule of thumb.....If it dont work, check power. If it works weird, check grounds. DC is a different animal than AC. And most of us tend to think in AC terms.

 

Thanks guys, I really appreciate the help.

 

I had some electrical issues on my 03 Ram, and not to say you have the same problem, BUT mine was the fuse box under the hood. 600 bucks for the box. (ouch) I did not have all of the symptoms you describe just some.
