Alternator conversion

[SKYLER53]

I hav a 1965 MF 135 Perkins gas eng that I think came with a generator. Previous owner put a alternator on it and it does not charge. Has
original wiring and and voltage regulator and not sure how to wire it properly for alternator. Anyone seen this before? What is the best way to
proceed. Get an alternator without internal regulator? Or rewire it? Thanks.

If you ask 100 tractor owners of their rendition of "Alternator Conversion", you may receive 100 renditions, ALL with very good merits.

I choose a one wire alternator,as the pulley sizes are such that the engine has to operate, only at 725 RPM to see charging.

Here is a ONE wire 12 Volt Alternator Negative ground:

Purchased from YT Tractor Site:

One and only one wire is ran to one side of Amp meter:

Other connector on Amp meter is ran to and connected to Positive supply from BATTERY at Starter:

Three cylinder Perkins Diesel:

I used a Lineman's pliers, removed all the old / original faulty charging circuit wiring and Voltage regulator:


Anything above 725 Engine RPM Alternator operates PERFECTLY:

MF FE-35 X

Here is how my brother mounted a one wire alternator on his 135, since it doesn't have a power steering pump he mounted it down lower, and tucked it in so it doesn't stick up, and out like they normally do.

How it looks mounted lower, and tucked in.

Found the hard way on a TEA 20.

Make sure the axle at full up on the alternator side doesn't hit the alternator or the pulley

Thanks for how to wire

In response to an email from Bob here is what it looks like

I built on the original generator plate and used the original adjusting strap. The first go used the hole line for the generator ears, which allowed the axle to contact the fan/pulley when the right hand side was full up. So I had to lift it for clearance. The fan belt has to be a bit longer - at the moment I'm using a B section which works as this is only a light load tractor.

Going again I'd probably find the correct length and section belt for an alternator conversion and build to use that. Or maybe convert to MF 35 B section pulleys if I tripped over same.
