Could be time for a New ECM too. Its really hard to say. I would check all of your grounds and connections first, but it may very well be that the computer is shot.

Lost dodge mind trouble codes;

OK sorry for the delay 14-16 hour days take alot out of a guy anyways here are the codes i pulled off of the smarty (to high voltage) :damnit. PO 238 map senser voltage to high, 563 chargeing system voltage to high, 118 Ect senser volage to high, 113 intake senser voltage to high, 123 TPS voltage to high, 606 ECM FAILER, 343 ESS voltage to high, 1286 accelerator position senser voltage to high, 1693 JTEC (smarty) cleared codes, 1475 Aux. 5 volt, voltage to high. Basicly the voltage is to high. I unhooked the alternator, unplugged the clip and the main cable, i even took the belt off like in the forum about the chargeing system with the wild freq. and back charge i am at a stand still the pumps are new other then the cold air intake the exhaust and injectors, smarty it is all stock. hope these codes help please and thank you:bow:

lincoln welder

The beauty of the classic 3 regaurdless of the year is the smooth clean arc and the ac 120,220 power for pipe welding your remote has ac power for hand tools. My welder is a 1991 classic 3d, with a Contenental diesel i believe how its spelled when i order my new classic 3d i will order the perkins they start better in the cold super quite and the 3ds have a 100% duty cycle at 300 amps mine is a 100% duty cycle 200 amps the price tag of $11,000 is something to think of, the turn around rate is well worth it.:Thumbup:

Yeah i put a ac inverter on mine. It helps for now. Its been played with! It will stack metal with the best of em up hill on pipe. But im fixin to order me a 300. That ac plug makes all the diference in the world. With perkins and remote bout 11650 out the door. I dont think thats too bad. Gonna keep my other one as a backup.

Voltage regulator is internal on the PCM...

So I know that the 12V trucks can put a old school voltage regulator on for a fix. But I've never seen it done on a 24V truck. I assume it could be done for a temporary fix...

But the ultimate way is to replace the PCM...

pcm its all electrical no doubt about it there is no response with the pedel the temp. gauge is off the wall there is no way it could be hot enough to max that gauge out, pcm must be a factory only item with a clip and a little bolt, just like everything else. That truck only has 196760 miles on it time for parts to fail. And i am also going to keep my 3d welder as a back up, as for a remote Cable electric in im thinking Louis. The # is on my remote if you need it they also have 120 plugs on it to.

So the pcm is the com. on the side of the block behind the fuel filter correct, or is that the ecm? Now do i understand this right by saying that everything passes through the pcm on its way to the pcm, or am i thinking backwards.

ECM is on the driver side of the engine block.
PCM is on the passenger side firewall.

PCM (Powertrain Control Module) controls the gauge cluster, transmission, SRS Air Bags, etc...

ECM (Engine Control Module) controls the engine (That's it!)

But the ECM communicates its information to the PCM for display on the gauge console. This is the reason why the P1693 error code is so common. Is because if 1 module has problems it will effect the other very quickly... Since all the P1693 error code is notify you there is error(s) in the other module(s). PCM and/or ECM module.

Hopefully this makes a bit more since now... Here is so pics for ya...

ECM-PCM connection...

I think you mean PCM... :poke:

Since the PCM controls the alternator and your overcharging problem that is giving you all your erro codes...

Like on my Mom's 96 Dodge Gasser it cost me a little over $500 for a PCM for her truck... But I got the Mopar Performance module. The stock module was $650... :sly:

But remember once you get the module it will have to be installed and flash with VIN information BEFORE you can even start the engine. This is what I went through fo the 96 Dodge and it replacement...
