im havin electrical problems. my tach n speedometer are jumpin all around, most of my warnin lights are flashing randomly n my alternator isn't working. i was thinkin maybe the crank position sensor but im no electrical expert. what do u guys think?

 

Mabe a loose ground

 

I would also vouch for a bad/corroded ground somewhere...

 

alright i'll check it out tomorrow after work. im wonderin if i didn't yank somethin loose during my trans swap cuz the gauges have been screwin up every once in a while since then

 

after i did my KDP i had the same issue. did not gap the crank sensor right.

 

I've also heard of similar issues due to a bad CPS.

 

sounds like a bad cps

 

thats what im thinkin. i've been workin alot lately n havent really had a chance to mess with it yet

 

ok so far i changed the CPS with the one off my other cummins, no change. called one of my buddies and borrowed the PCM from his 94, no change. i unplugged the cps and my tach is still bouncin. i thought the cps controlled the tach???? what the hell is goin on here? i have no WTS light, the alternator isn't charging, my tach n speedo are bouncin. i really hate electricity. im really pissed off and im about at my wits end.

i've now gone thru just about everything i can change and i've gotten nowhere, i've checked grounds, i just dont know what to do any more. can someone please help me

still fightin. i changed the ASD relay, n there are 2 relays on the the firewall about dead center of the truck. not sure what they do but i changed them anyway. next thing is the alternator.

a little background, the first time i noticed the gauges jumpin was about a week after i got the 5 speed in, i took my buddy for a ride, shifted into 2nd n got on it a little n it wheel hopped n the tach n speedo started bouncin for about a minute, then went back to normal.

should i even bother changin the alternator? i unhooked it today n it didn't change anything

 

stupid chrysler electrics

take it to a shop and get the altenator tested mabey its not putting out enough voltage,
did you check for bad grounds?
