Question about 2000 Harley Davidson FLHTCUI Electra Glide Ultra Classic

3 Answers

Stator/alternator question Is the stator/alternator on 2000 Ultra Classic a standard 32 amp single phase ? I resently purchased an Odyssey PC625LMJ battery and the battery manual states the battery will discharge around 150 miles with this system unless up graded or charged when not in use. Are there any other option if this is the case?

2001 Ultra Classic Battery went bad had to jump it quit charging. have a new battery now only shows 10-12 volts on the meter tried a different regulator with same results. tried to check stater with...


usually it is either the regulator or stator that dies
firstly check stator...(alternator)...set multi mtr at 500ac volts
connect probes (red/blk) to both wires from stator..output voltage should read between 100 acv mid revs to 150 acv mid revs
output to battery should be 13.5v -14.75v dc...if not then regulator is RS ...I used to fit Honda regulators 30amp type with 2 red and 2 green wires ..because it is a 3 phase regulator just disconnect one yellow wire
harley regulators are of poor quality...they have no on off switch like the japanese ones ..in other words when you turn off your ignition the harley regulator is still on
hope this helps

Tip

Generator Not Producing Power ? Stator Winding


There are 4 requirements that have to be met before a generator is able to produce power. Due to number of questions that have been asked, a Coleman PowerMate 1500-1850 with a Briggs and Stratton Engine will be used here.

1) The Engine has to be turning at correct speed
2) Field Winding (Rotor) on the alternator must be energized
3) AC Winding (Stator) must create a voltage in presence of magnetic field
4) Output passes through Safety Devices before it reaches an outlet.

This Tip will cover the Stator Winding.

The stator winding is the winding that is around the outside of the rotor. It doesn't usually move. Previously, the alternator design was called a revolving armature, in which the field was stationary (outside), and the stator (armature) was the rotating member. This quickly was replaced, eventually, by the revolvingfield configuration, since the brushes carry a relatively small DCcurrent, rather than a larger AC current with destructive arcing. Brushes were prone to failure due to high wear.

In the revolving field architecture,there are primarily 3 types of alternators: Single Output, MultiOutput, and MultiPhase.

The single output alternator is just that, it outputs a single voltage. Typically, it will be either120vac (60Hz), or a single phase 240vac (50Hz) depending on the country it was bought in. The stator winding of this kind of alternator has only a single winding, with 2 wires coming off of it. One of these wires goes to the neutral bus for the outlets, the other wire goes to the circuit breaker, and the other side of the circuit breaker goes to the outlet. Disconnect both of the wires, and use your multimeter to check the continuity between them. You should have continuity here. Also check each wire to the frame of the alternator, there should not be continuity here though. If you don't have continuity between the wires, or if you have continuity between the wire and alternator frame, then you have what is called a grounded winding. This will have to be addressed by a motor shop, or replace the stator in its entirety. It is generally more cost effective to replace the generator though. Remove and sell the copper wire, and use that money towards a replacement generator.

Multiple Output alternators are usually found in the next step up from "bargain" generators. These usually will have an output of 120/240vac, and likely a low voltage battery charging circuit as well (12vdc being most common). The stator for these is checked in the same way as a single output, with a caution on the low voltage winding. On the low voltage winding,there will be a single diode (called half wave rectification) or a full wave rectifier (2 diodes) connected to the windings. You must disconnect at least 1 wire from the diodes to check the windings, and both wires to check for continuity between the windings and the frame of the alternator. If you don't disconnect the wire(s), the 1 way nature of the diode will indicate no continuity when there should be,and may cause you to not see continuity when there actually is (to the frame).

If the low voltage winding is open, the generator is still usable for the 120/240vac features. You just won't have benefit of the low voltage battery charging circuit, which is actually a very poor charger to begin with.

On a 120/240vac alternator, there may also be a switch that turns the 240vac on and off at the receptacle. This switch is put here so that the 2 120vac windings can be put in parallel for greater current capacity if 240vac is not required. If you have 120vac, but not 240vac, and the circuit breakers are not tripped, this switch is likely the culprit. It is just a double pole double throw switch that is easily replaced with one of the same type, and same or higher current rating. Never switch from 120 to120/240vac or vice versa while the engine is running. To do so invites winding damage due to arc-over, and may damage any devices that are connected from the voltage spike.

MultiPhase alternators are nothing more than single output alternators with a twist. Rather than having a single winding, there will be 3 windings, with a 120 degree phase separation. The in phase neutral wires will all be tied together, but the phase outputs will be separated, and connected to the receptacle in a specific order. This is called a Wye (Y) configuration. An alternate configuration is when the windings are all connected to each other, end to end style. The junction of each connection is then brought out to the receptacle. This is called a Delta configuration. Three phase / multiphase alternators will not be discussed in depth here as a much higher technical knowledge will be required.

As far as the stator winding goes, that is it. If you have continuity where you should, and don't have continuity where you shouldn't, the stator winding is likely good. As mentioned, if the low voltage battery charge winding is open, but not grounded / shorted to the frame, the primary function of the alternator is still usable.

If your checks of the stator are good,time to move on to the next tip.

What is the stator on a motorcycle


The stator is the alternator as you would know it on a car. It is part of the charging system which consists of the battery, stator and a voltage regulator/rectifier.

Alternating current is generated by the stator and rectified to direct current. The voltage regulator then maintains the voltage to the battery and provides power for additional electrical loads, such as the lights and ignition system, at a constant voltage regardless of variations in engine speed.

2001 ultra classic not charging. and losses electrical power when hot in city traffic.


Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12 volts or better after charging.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor. Good luck

Stator plug


By "stator", I'll assume you mean the alternator, specifically the wires coming from it's stator coils that go through the crankcase, to the regulator.

The stator plug is at the front of the engine crankcase.
The starter is above the transmission.

There's a crankcase in between them, so no, you don't have to remove starter to do anything with the alternator.

Stator and reg keep going out


If your stator and regulator keep failing, it's generally caused by an overload. Have you added any extra lights or electrical gear to your bike? If so, you may be overloading your charging system. If your bike is equipped with a 42 amp system and when you've got all your stuff running it's drawing 38 amps, your charging system is working to almost capacity to provide the current that is being demanded. This causes the components to run hot and they fail. My advice to analyze your current needs on the bike and look for a system with higher output capacity or take some of the current demanding equipment off the bike. Cycle Electrics builds a "three phase" alternator kit that works well. I've installed several of them and never had a problem. http://www.cycleelectricinc.com/

Good Luck

2000 honda cbr929 i have a new alternator but the end has a plug on it the other end the plug was cut off . i have three wires on each end ant they all are yellow do the have a sequence and if not the bike...


trace your wires coming into the batery from your stator if the wires arent grounded than i would think that you could hook them up and they would charge but i think you have a ground coming off the stator that has to be hooked up look up wiring schematics for your stator to the battery and go from there
