All,

I have been having braking issues for over a year now since the rear bearing went out and welded the race to the spindle. Log story short, I think I have worked out all of the bugs from that mis-hap except for 1. When I hit any bumps (I live on a dirt road) the parking brake and anti-lock lighs flash. Its not a hard jolt that causes it, just a slight bump will make them come on then go right back off. Once I get on the highway, its goes off and stays off.

I plan to troubleshoot this problem this evening, and don't have internet at home, so I wanted to establish some direction here 1st:

I *THINK* there are some wires coming out of the RWAL controller under the truck towards the rear that run to the controller behind the glovebox. That said, my guess is checking those wires first for cracks & such. If that is not the culprit, can anyone offer any other advice to check?

Thanks!

Check all the grounds and other wires for cracks and corrosion or just being loose. It defiantly sounds to me like a loose or bad wire somewhere.

Get the code(s) from the RWAL computer, that will tell you what wire is chafed. I'd bet it's the one to the speed sensor on the rear axle.

Thanks all. I will check tonight Lord willing and report back tomorrow.

It did start raining here earlier, and I am not quiet as tough at Greg with his HG repair, so I may just wait till some nicer weather....

UPDATE:

I guess I am a dummy, cause I could not get the computer to throw the codes, so I went ahead and disconnected the wires that ran from the top of the axle to the speed sensor, and replaced it with new wiring.

So far so good, but when I was under the dash checking for shorts there I noticed my running lights fuse had melted. I replaced it, but was concerned as to why they melting and not the fuse blowing. Seems to me that the 2 wires after fuse must be rubbing against that buss bar bypassing & heating the fuse up to melt. Problem is the wires all looked good. So why didnt the fuse blow?

Harbor Freight Chinese fuse?

That was my 1st guess, but I put a new BUSS brand fuse in it and it did the same thing again.
