2012 RAM 6.7L Electric Problems

[Jeremy Reynolds]

I have a 2012 RAM 6.7L.

I'm having random electrical problems.

From time to time, the truck will freak out.

All the gauges will return to zero and then too max, then zero, all warning lights will come on include trailer brake, wipes will come on, and radio with go on then off.

This will happen for a few moments repeatedly.

It kind of acts like the ECM is being reprogrammed while I'm driving.

I thought it was the H&S mini max I was running, so I purchased an MM3 from DRD, and the problem popped up yesterday.

I installed the MM3 on Sunday, and the problem occurred on Tuesday.

It happened when I was driving down the road, a smooth road.

It stopped when I pulled into my driveway, but then I immediately started my truck this morning.

I freaked out for about 2 mins, then right back to normal.

Any ideas what could be causing this

Check all your grounds, frame, batteries, etc.

Please make sure they are clean and tight.

How old are your batteries?

God bless,

Thanks for the info; I was thinking the same with grounds.

I figured I'd see if anyone on the forum has had the same problems too.

The Primary is less than a year, and the second is maybe 2 years.

I've tested both, and they are fine.
