Delco-Remy Generator?

Paul in Edmonton · Nov 21, 2012

I'm visiting from the Ford 8N Forum...

My tractor has the original Voltage Regulator (Autolite VRR-4008-A), but the generator has been replaced with a Delco-Remy 1101355. Google seems to suggest this generator was used on some Farmalls. I'm wondering if anyone in this Forum has a wiring diagram for how that generator would have been installed on those tractors? Or even diagnosis instructions--I'm not sure to what extent I can use my Ford shop manual for this...

Thanks,

-Paul

The Delco has an A circuit style field setup. the Ford likely has a B circuit system.
The A system is a field supplied by connections to the Armature terminal for power, (or a third brush near the Armature "hot" brush) the regulator grounds the field terminal, regulating the field strength.
The B system internally grounds the field windings, and the regulator provides voltage to vary the field strength.
The diagrams shown in the link are for IH tractors, and diagnostics for them. Later series, SM or SH will have regulators.
Google A circuit and B circuit generators to become familiar with the serious (let the smoke out) differences. Jim

Good advice from my friend Jim, Im NOT in any way shape or form a Ford man but know hes right SOME Fords used a Class B system while MOST Delco gennys were Class A AND YOU HAVE TO HAVE THE CORRECT A OR B VR OR YOU MIGHT FRY SOMETHING they are NOT interchangeable.

You need to ask on the Ford Forum but I was thinkin the 8N was Class A while later Fords were the Class B BUT I REALLY JUST DONT KNOW. However many of the Autolite VR's were indeed for Class B SO AGAIN I DONT NOW WHAT VR YOU HAVE

If you have a good working Delco genny you wanna use I believe Id match it with a correct Class A VR (which ALSO is suitable for the Polarity you choose) and then wire like Jim noted. Id take it to an old fashioned mom n pop genny/starter repair shop if any exist anywhere near you n let them figure it out. I could lay out a bunch of techy info to help figure it out but that takes too long and if your not a techy type you probably wouldnt be able to follow me

Happy Thanksgiving

Let me comment that the genny/VR combo that's there has been there since I bought the tractor three years ago. (And since the paint on genny matches the rest of the tractor, and is old, I'd guess it's been there a while.) If they're mismatched, the smoke was let out long ago--before I bought it.

Having said that, it is entirely possible that the charging system has never worked since I've had it. I do put a battery charger on it from time to time. And the battery I bought only three years ago won't hold a charge anymore.

The VR is the early Ford one--they changed it later, so it's probably A--I can check that.

The 423 and 355 take a different reg than the 501 and 533 so be sure you get one that works for the 355. The one fits all dont work correct.

Delco-Remy 1101355 is the version used with a cut-out system. It was common on IH before about '49 or '50. Either use it with a cut-out or one of the regulators intended for backfit onto a cut-out system.
