SOURCE: CHARGER PROBLEMS

The flashing light indicates the charger is charging the battery (or attempting it) and if it never finishes charging you should try to charge a different battery, if the charger charges that one ok then the battery is bad.

My yamaha teo s 125 new battery fitted but still not charging


Hi, Birdy1995 the following is a comprehensive charging system test that is guaranteed to the find issue with your system.
1. Battery Test: The battery needs to be a fully charged battery that has been load tested to ensure proper readings. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Most places like Auto Zone, Advance Auto, and Pep Boys will charge and test motorcycle batteries for free. 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. Check Connections/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 test Fails and Resistance Check, and Stator IB Test Pass then 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 system, check service manual for specification)
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 IB test or 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 to ground your stator is shorted to ground.
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 ?

Dewalt radio 011 wont power up with ac or dc but the red indicator light will flash one time when pluged in either ac or dc but definitly got pluged into 240


Sound like one of the Capacitors on the Power Supply has blown.

If it's the same on both AC & DC then its probably on the output of the transformer.

If you can open it up and post pictures or see if one has a buldge in the top or liquid leaking out.

2005 Kawasaki EL 125 Eliminator is not charging


Hi, Leedhurn 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).

Battery #1 terminal lights red and stays red.


Disconnect the - lead from that battery, Repower the charger. The LED should be green. If it stays RED, charger defective.
Reconnect the - lead to the battery, measure voltage when charger is on. Should be between 11.5 and 13 volts. If OK, replace the battery. If lower than 11.5, check for charger cable connections OR for a connected load ( power drawing ) of more than 10 amps.

Battery goes dead. disconnect the battery and jump the car and it is ok for about a month


Get a battery check first and have it charged. Then, switch off all lights, radio, ignition switch. Reconnect the charged battery negative ground first, then, the positive terminal. Find if there's a spark. if it does, then, you must check your electrical wiring since this is grounded. Do not connect the positive terminal. Clear the grounded connection first. If no spark, go ahead. Crank your engine, and let it run at neutral position. And check the voltage that goes out of the alternator, this must be more than 15 volts DC. Then check the voltage output of the regulator which must be 13
to 14 volts DC. However, if you cannot get the right voltage at the
alternator., you have to replace it. Then, you can check the regu-
lator output voltage, and get the right voltage. Get this done,. and
send your e-mail for the result.

The battery has probably lost it's ability to receive a charge. Is it old? Check the output of charger, should be around 26 volts DC at the output jack.
