Alternator part number

I have an alternator on my bus, which is not original. It has a built in voltage regulator. The label on the VR states that it replaces a Leece Neville 79000. How can I find the alternator part number. I would like wiring diagrams, bulletins, etc. for the unit.

Re - Type A127-MT


A Prestolite Alternator Des No 47020067 Type A127 - MT 12 volt 70 Amp alternator is fitted to an engine on a narrowboat I am about to work on.

Could you confirm please if this is or is not an isolated return type, and point me in the direction of any information regarding this alternator.

External Voltage Regulation.

I have a new 90 amp Leece neville alternator. Model # is *MR2070TA. It supplies 660 amp hour "house" batteries on my boat. I have purchased a Xantrex XAR digital alternator regulator.
This regulator has a duplex plug (stator and field) Where do I make the required connections on the MR2070TA? I assume I disconnect the voltage regulator supplied.

Overcharging 4890jb

Hello all,

I am having an overcharging problem with your 320 amp 4890jb model atlernator installed on a '05 model e-one typhoon firetruck. It came to us with the typical cooked battery odor and was showing ~18 volts at the batteries at idle. The regulator appeared to be the non adjustable diode trio variety. I replaced the batteries as well as the regulator hoping this would cure the problem.

I followed the troubleshooting instructions on the website and still have not come to a resolution. I did see a tsb on this website concerning the rectifier, but it looks like it already has the updated version. We have already ordered a new alternator, but i'd like to fix this one and put it on the shelf for possible future use.

Thanks for any and all help!

Cannot find alternator part/model number

We have an old Ford tractor. Do not know the year. We suspect the alternator is bad; however, the part/model number label is blank from age, so we don't know how to find a replacement. We can still see the regulator part number which is 8RC2009A-336A. Any idea on how we can find out the part/model number?

Voltage Regulator Leads

I am replacing an incorrect alternator, installed on a used Case 850 Crawler Loader I recently purchased, with an OEM rebuilt alternator and a Prestolite 8RH3016K   24 Volt (200802) (Sales No. 105-177)(Amps 4) regulator.  The previous owner cut the connectors off the wiring harness and old regulator, and my Case service manual is not in agreement with the location and color of the wires from the 8Rh3016K Regulator, which are Green,Red and Black.  Can you please tell me which wire goes  where.  My manual has one to the Oil pressure switch, one to ground on the alternator, and one to the field terminal. Thanks, JoeR
