I fabed up a one off fuel pick up from a diesel fuel tank I found at the junkyard. Figured out how to fiberglass and made me a custom dash.



Now I am stuck… I need help. The fracking Alternator…



On the 1994 Dodge Ram 1500 trucks the ECM controls the Alternator by sending 5vdc to the Field terminals.I no longer have an ECM.


Control:
Alternator disconnected, truck will fire up and idle all day long, drove it around the block a few times. Didn’t go to far but kept it running for 45 minutes or so.

Try#1
I went and got a 12vdc to 5vdc converter and wired up the Field flash, fired up the truck and got 13.8vdc on the battery. The truck ran fine for about 20 seconds, sputtered and died. The alternator was hot to the touch.

Try#2
I got an external voltage regulator (1960ish style) wired it up thinking that maybe it would act like the ECM. The truck ran fine for about 20 seconds, sputtered and died. The alternator was hot to the touch.

I have looked for one wire alternator with the same mounting tabs as this stock one and no joy. Can anyone please help me figure out how to wire this so it works or link me to an aftermarket mounting kit so I can use a GM one wire.
Have you tried going with a Generator and not an Alternator? I am not entirely sure of the difference, except that I believe the Generator powers only the battery. Pretty sure the alternator "alternates" between providing power to the battery and the truck. Voltage regulator could work better if you installed an in-line capacitor...but there again you might not be shielded from EMP.

and for those that say this mod will cause a loss in power... I can burn the tires to fourth gear, cant even use first without smokin the crap outta my tires.

Just need help getting the alternator issue fixed. Not gonna get into a flame war about this. If its not EMP it will be CME. one way or the other, I have a great truck, more power then I know what to do with, and if SHTF, Ill be mobile. Its a Win-Win-Win for me.
Damn, you sound prepared. IMO though, I would have just bought an 85 or so Ram 150 or 250 for $1,000 and called it a day! LOL.
