my dodge pickup when first starting up for the day shows 14 volts charging the over drive does not work but goes into lockup. some times the tach will just drop and will not read shortly after thet the amp gauge will drop this whole time there is no overdrive
does your check engine light act like it shorts out when your tach falls if so my '95 dodge dually is doing the exact same thing and i have been looking for answers since january and i have had no luck but i am glad to know its not just minegood luck man
yep i was watching it to night when i came home and the voltage seemed to drop down to 12 volts like u said the check engine light seems to short out will yours reset its self whenn you turnn it off then turn it back onmine does not but if i let it sit over night it works just fine the next morning then it does it when i go home after work
I believe the alternators on older 12 valves have an external regulator. i can't remeber where it is located, but follow the large charge wire, and it will lead you to a junction block containing the regulator. Get it checked out.I know this might seem silly, but the tach on Gen 1 12 valves runs off the alternator, but I'm not sure if the newer 12 valves do too.Other things you can check is the firewall block (where the wires run into the cab). A 1/4" bolt holds the two halfs together, so try snugging it up. This would explain no OD. There is also a crank positioning sensor located behind the balancer on the gear case cover. I have heard of people have these go bad too.Thats all I can suggestRusty.
hold on wat does this 1/4 bolt do u lost me
Ok, every wire that runs from the cab out to the rest of the truck is contained in a plastic 2 piece firewall conduit (3"x3" square black plastic). One piece is inside the cab and has a large harness of wires running to it, same on the outside below the brake booster. They are sandwiched together and held with a 1/4" or similar screw in the center or 4 screws on each corner, (I can't remember which style the 1995 uses). Anyway, find the hardware that holds these two conduits together and "snug" them up. Don't overtighten!!!Rusty.
is this bolt or screw on the inside of the cab or the outside on the engine compartment fire wall
On the engine compartment firewall. At the factory, the seal the area with tar adhesive, so you might have to "dig" carefully to access it..
k tach and charging fixed still no overdrive
On the 96 dodge ram diesel the charging is controled by the ECM. inside the ECMis the sense module, it knows your daily driving and tells the generator to charge batteries. if it is not charging check ASD relay in black box in engine compartment.it is cheap i would go with a new replacement. in cold climates the overdrive will not work until engine and trans warm up, this is also controlled by the ECM.Tachometer is controlled by crank position sensor.There is also a relay for trans next to ASD relay in black box, again they are cheapreplace it.94 95 96 Dodge Rams are the same, they changed in 97 on.
my box must be diffrent i dont have a asd relay
is there any way to check the overdrive electrical wiring and the over drive it's self it goes into lock up but does not drop the next drop on the tach like it doesnt act like it drops 5 times just four
????????? Punctuate, so people can read what you are typing without having to read the really long sentance 18 times to figure out what you are trying to say when it should only be read once it is very annoying thank you .
Sorry used to texting to much. Ok i was wondering is there any way to check the overdrive wiring harness. Is there any way to check the transmission part of the overdrive system basically how can i check the overdrive system
I'm having problems with my charging on my 95 Dodge diesel. I was told there is a voltage regulator (built-in) in the ecm on the firewall behind the air box. I took the ecm off a deferent truck did not change anything. where do I look now?
