The whole 100 amp system is trouble prone, that's why most chose to stay away from it.

As you apparently have already realized, the system is outdated technology many times over; components if you can find them are expensive; and getting components serviced is next to impossible. Sure the system looks great under the hood of a truck that has all the radio equipment installed and is a great show piece that we no longer see every weekend at shows.

BUT, reality becomes a factor in that if you really want a reliable 100 amp plus charging system; it can be had in a single self contained Delco-Remy alternator these days. The Delco conversion with 100 amp capability can't be done on the cheap because of the unit cost, but it is a relatively simple installation, and one that will give years of reliable, very low maintenance service.

Now if appearance is the driver here instead of real reliability, that is another thing that I totally understand in a sense. You will simply have to make up your own mind about the direction you take with that. Boils down to putting up with the issues and high cost of yesteryears technology or installing virtually trouble free reliability.

The answer to your question concerning the weakest link; have you ever heard the old saying; "all over more than anywhere else?" That is truly my opinion of the original 100 amp system in today's electronic world. It is simply days gone by.

hi,and thanks for the commentary that makes perfect sense,but yes i am striving for originality because i have come so far and spent so much !! so before i go any other route i want to do my best to make this work rather than throw my hands up !! and go off on another idea,yes even one making more sense than just leaving a wasted pile of money in my wake,i am very surprised that nobody has said anything of a similar problem only condemming the system.i would love to get in contact with someone who knows about this and can see it in person and help or even look into taking the truck to them,i like to believe even though the technology is old it still had to be somewhat reliable,after all we trusted mens lives to these machines,i'll get it going somehow before i switch i believe,to update in a way seems like i should buy a updated vehicle,i want to preserve history in it's entirety,just my thoughts thats all........

Like I said before, nothing wrong with the purist view if that's what you want and you want to keep spending. I'm not saying it can't be fixed and functional. You may get lucky and not spend a lot more, or you may not be so lucky. People who have the expertise to service the stuff are pretty much now features of the past. Internal parts to repair these items are not on every shops shelf. Get young service techs to even look at it, good luck with that one. But hey, maybe you will be the lucky one who finds that lone tech who might be curious enough to try and help you. I wish you the best in the endeavor, heck I wish I could help you.

nutsfor59 , I say go for it,it's nice to see someone keeping one stock. Not all of them need a diesel engine and power steering ,upgraded brakes heat, air conditioning etc. The search for the right parts is part of the fun in the hobby. Good luck .

Give John at Midwest Military a call he may have something or be able to guide to someone who does.

Just looked on Midwest's website, he has alot of 100 amp parts on the the M37 parts page.

hi again,as a matter of fact john at midwest has been of the utmost help with parts,trust and tech advice,i would say 95% of my project has been purchased from him almost all my 100 amp stuff my arctic and personel heaters and so on,that alone has got me through alot of frustrating times and situations,and made this a really rewarding hobby and project,if i have to ever resort to modern stuff i'll get a modern truck,whats the real value in altering the past,almost anyone can do that,to me thats taking the easy way out,the real reward out of this stuff is learning of and about the past and once up and running actually enjoying the thrill of living it !!! and realizing those stories our fathers and grandfathers were not b.s after all,the life and military we enjoy today is only because this stuff had come before right ??
