Question about 2000 Harley Davidson FLHTCUI Electra Glide Ultra Classic

2 Answers

I have a 1990 flt tour glide classic and its not charging correctly, the gauge is under 12 volts unless you rev the engine and the speedo reads too slow and when you stop it gradually goes to 10mph, its driving me nuts.

Let's start by taking the battery out and taking it to an automotive part store. Ask them to load test the battery for you. They'll usually do this for no charge. If the battery test good, put it back in the bike and make sure it's charged up fully.

Now, connect a DVOM (digital volt ohm meter) to the battery. Red meter lead to positive, black meter lead to negative. Put the meter function knob on DC Volts, 20 volt or greater range. Start the engine and bring it to a high idle. You should be reading 14.5-14.8 volts across the battery. If not, check the output of your alternator.

Unplug the regulator down at the cases just to the left side of your oil filter. Look down into the connector and you'll see two pins. Put your meter's function knob in AC Volts, 50 volt range. Start the engine and bring it to a high idle. Touch one lead of your meter (either lead) to one pin and the other lead to the other pin. You should be reading thirty volts or more.

If not, you probably need to replace the stator in your alternator, If you read 30 volts or more, replace your regulator.

Now, as to whether or not this will correct your speedo problem, I have absolutely no idea.

Good Luck

Your speedo is connected to your radio volume control system. it's more digital than mechanical.
I can get my bike speed up to 70 and the speedo is only 25 but it climbs slowly. The volume on my radio goes up and down with that speedo Gage. At a stop light my radio volume comes down with the speedo.
I hope this helps ya.

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

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

Alt gauge reads low


This sounds like the alt is not charging, but a eak battery will also cause this condition, what you can do is have the charging system tested. if you have a volt meter you can connect it to the battery with engine running and acc off you should have 13.5-15 volts,this is a good alternator, then turn on all acc and check it, it may have a low reading but should atleast go to 13volts and then when you rev it up it should go to 13.5 - 14.7. if the readings are low replace alternator.

The AC output of the stator should be 32-40 volts at 2000 RPM (16-20 per 1000 RPM). With the battery fully charged, your regulator should supply between 13.5 and 15.0 DC volts to the battery. This should be the reading you get on your voltmeter. It will vary depending on what lights and other equipment you have turned on. Sounds like everything is working fine to me. The gauge is reading the DC voltage at the battery while the engine is running. At 2000 RPM, 12 volts is a little low but, considering the accuracy of the gauge, as long as it doesn't fall below 12 volts, it's about right. You don't ride for extended periods at engine RPMs that low. Then at 3000 RPM, 14 volts is about right. If your bike never ran anymore than 12 volts, your battery would slowly go down. If it goes any higher than 15.0 volts, it will boil the battery. Usually, about 14.3 or so with no load on the system is about right.

Good Luck

I just purchased yesterday and found recall notice in upper tour pack. The battery was low charged over night and am going to check voltage and amps at battery while running today. What are the telltail...


With the battery fully charged, use a DVOM (digital volt ohm meter) to check the output of the charging system. Connect it across the battery, red meter lead to positive, black meter lead to negative. Put the meter's function switch in DC VOLTS, 20 VOLT range. Start the engine and bring it to a high idle of about 1500-2000 RPM. The meter should read 14.5 to 15.0 volts.

If the meter does not read correctly, unplug the regulator where it enters the front of the engine case. You'll be measuring the AC voltage at the engine case side of the plug. Put your meter's function switch in AC VOLTS, 50 VOLT range. Put one meter lead into one metal contact in the plug and the other lead into the other metal contact in the plug. Makes no difference which lead goes to which metal contact. Start the engine and bring it to a high idle. You should read 30 volts or better.

If you do not read 30 volts at the engine, your stator is bad. If you have 30 volts or more at the engine but low voltage at the battery, your regulator is probably bad. This is a simple test and it's accuracy is about 90% or so.

Good Luck

A 93 flhs loosing charge in less than 2 hour


sounds like your battery is not charging from the engine. Most likely the cause of this is, a faulty Rectifier.
I suggest you charge your battery up, put it in the bike and start it up. Using a Volt meter, check the reading, to see if charge is going into the battery, reading should be about 14V with a little rev of the engine. If the reading remains at 12V, then ther is no charge going in.
If you have charge going in to your battery at idle, 13.5 - 14Volts,
Then i suggest your battery is faulty.

Voltage problem when running bike


The voltage regulator should present 13.5 to 14.5 volts at the battery to charge it properly (engine at fast idle). I'm not sure if the V regulator is adjustable or not. If not, then it probably needs to be replaced. The alternator appears to be trying to do it's job, although it may have an open diode or winding if the alternator is 3-phase. An oscilloscope is the best tool to check for all three phases working properly. Good luck!

Dont do that, your voltage regulator is faulty. It is in the alternator. Max charging voltage should be 14.2 and min 13.6v. Chk battery water level. but get an alternator 4 sure
