Is there a bench test for N3135 dual voltage 200amp regulator

[TOBASH]

Just picked up what looks like a solid used N3135 dual voltage regulator for 200 amp dual alternator unit. Bargain basement price $150. I couldn’t resist, but does it work???

Is there a bench test for it? The rig is in California and the regulator is in NYC. I’d like to check the unit before sending it out.

Also, before I go digging, anyone know off the top of their head what screw size secures the unit to the alternator? Otherwise I’ll check the TM.

Thanks

The only troubleshooting guide I am aware of for these is the one from niehoff, and it doesn't appear to have any bench test procedures.

The only way you are going to be able to tell if it actually works is to bolt it up and test it on the alternator.

Thanks Coug!

I have a spare alternator and I have high power drills. I guess I will use them for a bench test.

Don't you have another HMMWV in NY?

Thanks to all of you.

Coug, that manual is really helpful!

Thanks to all of you.

just one of the many bookmarks I've made while finding information to fix my own truck.

I have 7-8 I need to test here. I’ve tried every drill imaginable-I can hear when the alternator “loads” but just can’t spin it enough to get actual charging out.

It only takes a few minutes to swap one out, surly you guys know someone local that has a 200A HMMWV.
I would be happy to test them, but of course there would be shipping involved.

For this type of tests I have a 3/4hp (110v) motor with a skateboard wheel, and another 2.5hp (240v) motor with a heavy rubber cart wheel on it. I bolt one on the workbench, securely lock an alternator in the vise (using mounting bolts on a thick plate) and from there I can test them at 5-6 thousands RPM and use an old PWM light variator for the smaller motor so I can modulate the speed easily.

For large alternators and other smoothly spinning things where I need to test with some load I use mostly the large motor with the cart wheel. It was a pool skimmer motor bought on surpluscenter.com for about $80 and has been very convenient!
It leaves some rubber on the pulley which sometimes is a dog to clean, other than that it works great.

Love to see a pic of this.

You can always take it to a local starter/gen shop and have it tested, most do it free for reg alternantors but my local shop charges $20 because it is so heavy which makes it a hassle to set up.

l'll take some this weekend. It's very simple, really. A wheel on a motor.
I always have 2-3 spare wheels, they need replacement once in a while as the rubber starts peeling off after a few dozen hours of use, particularly when using them against pulleys with deeper groves.

I totally forgot, sorry. I'll find it in the garage sometime this week to share a photo. The sanitation of the A2 has kept me busy this week-end!
