abs & brake light stays on
I just bought a 1990 cummins 4X4, what a tough truck! The abs & brake light seems to stay on? Any obvious reasons why? Brake reservoir is full.
thanks
Doug

make sure there is a vaccum line that runs from the brake to a small circle like object on your driver side inner fender, it tells your truck if you have vacuum or not. someone might have broke it like a lot of us have

yeah, sorry, i was thinking it but not typing it! there should be one 1 vacuum line that comes off of the booster, then T's off and goes the the cruise control if u have it, and the vacuum sensor that i was telling you about

Hey Nelly, do your start and water lights work? My brka and abs stay on and the wait to start and water in fuel both come on (only) when I hit the starter. I was told it had somthing to do with a ground, any more advice Dean Snow?

My brake and abs light is on constant and my wts light blinks. I have just learned to live with it, mainly because I'm lazy and now it's to cccooolllddd out to fix it.

I'd say, if it is a ground, find the ground and reground it yourself to see if it fixes it? I'm not sure if the computers run all of that stuff, but im guessing it does. Turn your key on(not to starting it) and do that 2-3 times then leave it to on, then count the blinks if it does any. Fast blinks and slow blinks if i recall right. I haven't had to do it in a long time

Well for the brakes I think that I might have pulled on a wire or have air in the abs unit on the rear frame rail from when I dropped my fuel tank. The master cyl lid leaked since I got the truck and I always had to add fluid, now I replaced it and rebled the lines but not the abs unit. As far as the wts lite I have no clue but I plan on getting the old meter out and checking things once it warms up. The light blinking on the dash doesn't bother me it's the head lights pulsing at idle that really earks me.

The wife's truck has always had the headlight pulsing, along with the volt-gauge wiggling.
The cure for it is to replace the voltage regulator with the BLUE MOPAR racing regulator.
Several other 1st Gen.s around here also were pulsing and that BLUE regulator stopped the problem for good.
When I replaced her right-side P-brake cable, after having to remove the old one from under a bracket on top of the differential, her ABS and BRAKE lights have remained lit ever since.
When time allows, I am gonna rip out all that silly mess and make it all old timey.

Thanks for the tip BK I think I even have one of them lying out in the shed and if not I know a car I can get it from. Don't worry he owes me money any way
