on my 180D I think has shot manure, the alternator checks o-k, AGCO says they don't have any, found one at an auto parts store and it looks the same, but is about a 1/2 pound difference in weight, and of course it's made in china. does anyone have a part # for it? I forgot to get that when at AGCO.

I can't help much, but good luck. Every time I hear "voltage regulator" I get a shudder... I've had nothing but trouble finding good ones for my tractors.

Dale, think it should be either 70243986 / 72072955.
Some parts counter books show 2 regulators for the Delco 10DN alternator, 1 for ammeter and 1 for idiot light setups. You need the ammeter 1 if they ask..
I've had good results with electrical parts from ASAP @ 1-877-530-4430. Their part  number is 105289 price is $17.00. 2 - 3 business days for ship to your door. The 1 on my AC200 been on 8-9 years so it must be OK. Have not had any bad experiences with their parts.
AC 200, CAH, AC185D bareback, AC 180D bareback, D17 III, WF. D17 Blackbar grill, NF. D15 SFW. Case 1175 CAH, Bobcat 543B,

Get yourself a 10 SI Delco 3 wire alternator with a built in electronic solid state voltage regulator like this one https://www.dbelectrical.com/products/alternator-tractor-delco-10si-with-tach-john-deere-allis-massey.html?mrkgcl=1145&mrkgadid=3179676962&rkg_id=h-03354b6c5c788d75ac5a9016d58d72e1_t-1512130026&adpos=1o2&creative=196860178238&device=c&matchtype=&network=g&gclid=Cj0KCQiAmITRBRCSARIsAEOZmr7l4ryO3XcFCdg66svdEwTTftFkDs_KZmEG4L1qInWFEibFS4EUjzcaAviOEALw_wcB

I converted my WC to 12V 20 years ago and used one of these alternators and never had any problems. I use my WC year round. Very very reliable. No more troublesome mechanical voltage regulators.


The diode is so the engine won't keep running after you turn off the ignition. Power to this terminal is required to excite the alternator to get it charging once you start the tractor. The diode can be eliminated with a momentary on switch (spring loaded to off). You'll need to hit the switch when you start the tractor to excite the alt and start it charging.

I have a NAPA one that I bought for my 175 which I am not going to use. I would let it go cheap. New in the box. I remember it being around $60? Let me know and I can send you some pics.

A CS130 (not the D model) already has a resistor built into the “I” terminal. You shouldn’t need a resistor or diode or light. Just hook it directly to the ignition.

Problem with a standard Delco is you lose the Tach for the tractor on the 180/185.

Actually you don’t. Your tach may not read quite right if the tach alternator has a different number of poles. I am assuming it’s an electric tach.
 
Edit: Whoops.  Alternator poles, not tach poles.

The auto parts store voltage regulator is probably the new electronic type while your old one is the mechanical with points type.  I have had good luck with auto parts ones so far.

When purchasing Voltage Regulators, get the number off the Alternator and then match the correct VR to the Alternator number. This way you know the VR is designed to work with what Alt you have.  That's why a lot VR's fail. They're not mated to the Alt they need to team up with. The China thing doesn't help either. Make sure the VR is grounded properly to. Very important.

There are some smart regulators out there that can be configured to fit any P-type alternatores. Most externally regulated alternatirs are this type. One this type of regulator you can configure the maximum field current; the charge voltage; the charge based on battery temperature and set it for two or three stage charging. Google “smart alternator regulator” for a look. There’s one out there for $149 I think. Xantrex is one name that comes to mind.
