Harley battery won't stay charge


Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher than that you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
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 while cranking 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.

1984 Honda Goldwing Gl 1200 not charging


Hi, Anonymous before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Battery Test:
The battery needs to be a fully charged and load tested to ensure proper readings, connections need to be clean and tight. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Standing battery Voltage should be 12.5-13.2 DCV.
2. Charging System Voltage Test:
Start motorcycle, measure DC volts across the battery terminals you should have a reading of approximately 13.2-15 DC Volts.
3. Connections and wires:
Inspect the regulator stator plug, and check the battery terminals for connection corrosion. If everything seems to be in order, move on to number 4 below to determine if there's a failed component.
4. Stator Checks/Rotor Check: Each of the following tests isolates the Stator & Rotor. If AC output and resistance test fail and stator test passes then the rotor is at fault (Pull Primary covers and inspect rotor for damage).
5. AC Output Check:
Unplug the regulator plug from the stator start motorcycle and change Voltmeter to AC volts. Probe both stator wires with your meter lead. The motorcycle should be putting out approximately 18-20 ACV per 1,000 rpm. Reading will vary depending on system, check service manual specification
Generic Specs:
22 amp system produces about 19-26 VAC per 1,000 rpm
32 amp system produces about 16-20 VAC per 1,000 rpm
45 amp system produces about 19-26 VAC per 1,000 rpm
Stator Resistance Check:
Switch your multimeter to Ohm x 1 scale. Probe each stator wires with meter leads and check resistance on the meter.
Resistance should be in the range of 0.1-0.5 Ohms. Reading will vary depending on the system, check the service manual for specifications.
Generic Specs:
22 amp system produces about 0.2 to 0.4 ohms
32 amp system produces about 0.1 to 0.2 ohms
45 amp system produces about 0.1 to 0.2 ohms
Stator Ground Check:
Switch your multimeter to Ohm x 1 scale.
Probe each stator wire with your positive lead on the multimeter and the negative to ground.
There should be no continuity to ground on either wire.
If there is continuity your stator is shorted to ground and must be replaced.
5. Regulator Test:
Each of the following tests isolates the regulator only, so if any of these tests fail, the regulator is at fault.
Identifying Wires:
Battery Charge Lead- Wire going from regulator to battery positive.
AC output leads- Wires coming from the Stator to the regulator.
Ground- Wire from Regulator to ground or regulator may be grounded via the physical bolting to chassis.
Regulator Ground Test: Ensure the regulator body is grounded or grounding wire is fastened tightly to a good ground (you should verify this by checking continuity from regulator body to chassis ground).
Fwd/Reverse Bias Test/Diode Test:
This check is testing the Diode function to ensure it is regulating the AC current for the stator into DC Current.
Switch multimeter to Diode Scale.
Place your Multimeter positive lead on each AC output wire.
Place your multimeter negative lead on the battery Charge wire.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the AC output wires and the Positive lead on the Battery Charge Wire. The reading should be Infinite. With your meter on the same setting, place your multimeter positive lead on the regulator ground wire or to the regulator directly, and then place your meter negative lead on the AC output leads.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the regulator ground and the Positive lead on the AC output wires. The reading should be Infinite.
Note: Below is a table to show the readings:
Positive Lead Negative Lead Reading
AC output 1 Battery charge lead Voltage
AC output 2 Battery Charge Lead Voltage
Battery charge lead AC output 1 ?
Battery charge lead AC output 2 ?
Ground AC output 1 Voltage
Ground AC output 2 Voltage
AC output 1 Ground ?
AC output 2 Ground ?

I cant get my power chair jet 3 to charge batteries are good


Hi valentin 201
I have owned my own business for 3 years and have been working on scooters and powerchairs for 15 years. . In the future give as much info about the scooter as possible.

1. load test the batteries even if you think they are good, check anyway. Sometimes even new batteries won't hold a charge.

2. Your charger on the powerchair must have enough volts to open the charger inhibitor. That is, the charger won't even start up if your batteries are low. Both batteries need to have at least 20-22 vdc.

3. Some chargers have a 3amp fuse check that and repace if needed.

4. With a multi meter set on dc200 check your batteries. Red on one battery and black on the other. Check to see what you get for voltage. If no voltage reverse the lead wire to the other posts. Once you get a reading of 20+ volts watch the meter and plug in the charger, it should increase the volts on the meter. if not the charger is bad, replace. Charger should be 24-31 volts to be a good charger.)

One of these sugestions will fix the problem

Good Luck

New batterie new negative wire new posative wire but wont charge . are there any reiays or fuses causing this problem?


You need to check the output of your alternator. You'll need a DVOM (digital volt ohm meter) to check the outputs.

First connect the meter across your battery. Red meter lead to the positive terminal, black meter lead to the negative or a good ground. Put the function selector of your meter in DC VOLTS, 20 VOLT RANGE. Start the engine and bring it to a high idle, 2000 RPM. Your meter should read 14.5 to 15.0 volts. Turn all lights on and make sure the voltage stays the same.

If your meter reads low in this test, you need to check the output of the stator. On the lower left front of the engine, you'll see a plug where the voltage regulator plugs into the engine case. Unplug this plug and look into the part that is in the engine case. You'll see two metal contacts. These are what you're going to put your meter leads to in this test. Since the voltage is now AC volts, it makes no difference which lead goes to which contact. Put your meter's function selector in AC VOLTS, 50 VOLT RANGE. Start the engine and bring it to a high idle. Insert the meter leads into the contacts. The meter should read at least 30 volts AC voltage here.

If the alternator stator test fails, you need a new stator. If it passes the test but the voltage to the battery is low, you need a new regulator.

If both pass the test, you need to evaluate the current draw of any extra lights or other equipment that you may have put on the bike. If your equipment is drawing more current than the alternator is capable of producing, a slow drawdown of the battery is the results.

You need to check the output of your alternator. Unplug the regulator from the wires that come from your alternator. Put your meter function switch in AC VOLTS, 50 VOLT range. Start the engine and bring it to a high idle. Insert the meter leads into the alternator side of the plug. It doesn't make any difference which lead goes to which contact because you're measuring AC voltage. You should be reading 25 volts or higher from your alternator.

If your alternator is putting out 25 volts or better, and your battery is fully charged but only reading 12.3 volts, then your regulator is probably bad. It should be reading 14.5 to 15.0 volts when checked with a fully charged battery.

Make sure the regulator is grounded well to the frame and all connections are tight and clean.

Good luck
