Alternators

identify alternator application

Hello,
I have a customer that asked me to help identify a alternator he has on his shelf.
Orginal id plate list it as:
2600JB
14V 3step
p/n 102000

Just a general ideal what it is most popular application it was used in ?
And what is 3 step ?
Why is it a 14volt when all aplications are usally 12 volt ?
Thank You

help please...

I have a Leece Neville 24 volt 200 amp alternator. It charges my 24 volt batteries for about 20 minutes then drops down to 10 amps.

I am using this to charge my house batteries that are fork lift style deep cylcle lead acid batteries.

Do I need to isolate the chasis of the Leece Neville from the charging generator frame (which has a 12 volt starting system)?

I just need the generator to charge at around 80 amps for 4-5 hours. Is there any way I can do this?

Sincerely,
Mark Rankin

8SC Questions

I have an 8SC @ 24V. It fried the + & - studs off the back. My electrical shop handed me a 8SC 12 volt and said to change the wires to match the 24 volt where the wires come from the diodes and go to the 3 wire terminals that the stator attaches to so the 12 volt back section looks like the 24 volt section. Then he said to put my 8 RL 3013 AG regulator on the back of the 12 volt section and I would have a cheap repair. Well I do have a cheap repair, but it won't work! I used all the old 24 volt parts except the replacement diode case on the back of the alternator. The wires all look right except 2 of the bridge solder point wires are on the opposite side of the bridge as the 24 volt.(The diode wires are attached to the opposite ends of the bridge on 2 of the 6 sets). I have 14 volts going to the 8RL 3013 AG. If this was a bad experment, tell me. Do I need to buy a 8SC3017 VA with 8RL 3013AG or a 8SC3018 VA with my 8RL 3013 AG? Also, is a 105-383 a direct replacement for my 8RL 3013 AG? This unit runs the A/C on a motor coach. (Once again, it is started by 14 volts.)

N or P type alternator

Hi- My question is whether alternator(type)4629JA
(model)A001090855 is P type or N type.
Thanks,

VOLTAGE REGULATOR- CARGO ( 135231)

We are using the AS123 series ( 66021616 )  Prestolite charging alternators for our AKSA generators / Cummins engines. The voltage regulators for these alternators are of make CARGO ( Part No. 135231 ). It has been difficult to source a supplier for this regulator. Is it possible for you to provide us information regarding suppliers for these regulators? I look forward to your co-operation in this regard.

Continuous rating of Leece-neville A0014729lc

Hi all.
Could any one tell me the continuous rating for a leece-Neville, model A0014729lc, 140amp, 28volt,machine?
Sales no-4729lc, reg no-96852 28v.
Engine room temerature 30 degC +.
Many thanks.
Howard.

CW or CCW Operation

This maybe a very general question, but do Prestolite alternators operate in CW and CCW direction? If so, do CW and CCW have the same performance?

Alternator Failed After Jump Start

2002 monaco Dynasty Coach. After jump start, alt fail light on dash and no charge condition. Alternator is a 4884JB 200 amp unit, DUVAC system. Removed alternator and had tested, no output. I had someone try to repair it. He said diodes had failed and replaced them. Now when I reinstalled it I'm getting 24-27 volts output. I have 2 new fully charged batteries installed. It uses a battery isolator and I beleive it has also failed, I read the same 24-27 volts at the alternator terminal of the isolator but battery voltage on the chassis battery terminal. Maybe a good thing it's no sending 24 volts through to the batteries.

My question is could something be done wrong in assembly of the alternator to cause this??

High Output Voltage

Hi -

I am sidelined along the Interstate with high output voltage from a 110-912 Alternator in a Monaco RV.

Initial problem was dead start batteries, but when those were replaced I started to get a high-charge voltage on that circuit. When cold, it will show a charge and voltage of ~13.7 or so, but within 2-3 minutes (I'm guessing when warmed-up) it will start to crawl up to about 14.9 volts, lighting alternator-charge light. The output was confirmed with a DVM at the batteries.

I may be able to limp to a facility, but have not been able to find anyone anywhere that has a replacement alternator, or am I even correct in targeting the alternator as the fault?

Thanks!
Ron
