I did look into having it converted to 12 volts which basically involved replacing all the guts with 12 volt NPR stuff.
The other problem is then the starter is still 24 volts.
We use 12 volt electric vacuum pumps on all our electric powered trucks so I can go that way and use a standard alt.
We also use DC-DC converters a lot and could run a 24 - 12 volt converter to run the 12 volt system or convert both alt and starter to 12 volt and get an ECM out of a 12 volt NPR.
So many choices, so little money.
I pulled the cab off the truck today and pressure washed it so I can give it a coat of gloss black epoxy paint.
I hope to install all the running gear into the chassis and then drop the cab back on.
I hate trying to wiggle around an engine compartment when your trying to figure stuff out. This way I can work on the engine, exaust, fuel sytem, all out in the open.
Like on the Jeep the tach sensor is going to be a problem, it had a sensor on the block that picked up gaps in the ring gear. I supose I will build a smaller version and bolt it to the front pully, I was going to try this on the Jeep but might get the Dakota running before my wife lets me "fiddle" with her Jeep.
