I'm pretty sure Ryan modified the GMC np205 transfer case support, nothing under the tranny.

Hi Ryan. Do the tie rod ends in this pic hace a oem application? Im going to have to do something like this for my 56.

[Dieselwrencher]

Yes I believe they are Chevy D60 tie rod ends.

Yes, but you could use 2 rights or 2 lefts. You can't really turn the bar to adjust where you want it due to the bend in it. You still have to remove a tie rod and adjust it.

Ah, makes sense. I didn't even think of that, durr...

Help!!!!!!! These pulsating gauges are driving me crazy. I can't believe there's not a fix. I replaced 1 battery and installed new voltage regulator a early dodge 2 wire style. Have combed every ground I could find and cleaned and rehooked up. From my research it sounds like a bad ground can produce these symptoms. When the truck is first started it is fine and then after about 30 seconds everything starts pulsating, Gauges, lights, heater fan, heck even the motor sounds like its chiming in. Everything seems to work and system is charging just very annoying. Wondering if anyone has any ideas for a work around. The guys at the fire station are wondering if the voltage regulator has a weak capacitor. If so would ther be a better way to go. do they make a alternator with a built in regulator that would fit a 1st gen cummins. Any help or ideas would be welcome.

Does it have a lope at idle? And does it do it just at idle or all the way through the rpms too?

Dosen't seem to lope and pulsates all the through just not as bad at higher rpm's

[1985-GMC]

Sounds like it could be a bad regulator, have you checked what the alternator is putting out with a volt meter?

autozone ran diagnostic's after i replaced napa's regulator with a new one. Alternator putting out 14.2 batts good alternator good regulator good. I'm in way over my head, but it seems like a regulator problem.

wondering if there's a better set up?

[1985-GMC]

I would go and check everything over with a volt meter to see what's going on. What is your grid heater doing? Check your fuseable links too. A Chevy 120 amp v belt 1 wire alt should work, just change out the pulley for yours.

You can try a Ford external regulator. You can get one at any parts store. A 1991 Ford Diesel would have one.

You won't find much else for a First Gen dodge application other than what you have, or using a factory ECM..................

After some research and talking with some others who run these dodge external regulators, this is just a normal characteristic with these.

The local Alt and starter guy converted my stock dodge alt to 1 wire. I saw it on the test bench . 14.7 V and 90 amps ? if I recall. I can ask what he did tomorrow.

Its on the truck now and seems to work well. I however have not had a volt meter on it yet. The lights go much brighter when you start the truck tho.

Happy days, Don't have the foggiest idea when it comes to electric. Ryan nailed it with the 91 ford voltage regulator. I just followed his diagram with some positive re enforcement and now the gauges and lights are rock solid no pulsing and the system is charging at 14.4 volts. Thanks Ryan

Wow. Who'da thought you could fix a Dodge in a Chevy by installing Ford parts?? Ford electrical parts at that?!? Dogs and cats living together...... Glad you got it figured out. I dealt with a vehicle years ago that had a mild case of the fluctuations and even that was annoying as all hell.

I love this Frankenstein! If it wasn't a "smoker" I would own one. This is Hot Rodding at it's best. Reminds me of the 60's when we would use ANY motor we could find to make our cars run.

I'm having the same issues with my lights pulsing using a 2nd gen dodge alternator and a dodge external regulator. Guess I'll try the f&^d regulator as well.

[v-man]

It's worth a try, my system is still rock solid.
