Charging Coil GHG3326258

Replacement Charging Coil.

Roary the Repair Lion says:

This charging coil provides 16-22 volts AC to the Electric Start System. This is also where the charge to the battery is produced.

If you having issues with charging the battery it will be a failure in the charging coil, the Battery Charging Rectifier or the Battery.

Testing:

Testing the Charging Coil and the Battery Charging Rectifier (BCR) can only effectively be performed with the engine running, so for this you will need to use the recoil starter if your engine has manual start. 

 Battery Charging Rectifier (BCR)

1. With a multi-meter, you need to check the input to the BCR from the Charging Coil behind the flywheel. Input should be between 16-22 VAC. Anything outside of these values indicates a problem with the charging coils. Replace the Charging Coil and the BCR as it will also have failed if the voltage was higher than 22 VAC. Replacing the BCR alone at this point would lead to another failure. 
2. If the voltage input is correct, we then need to test the BCR's output to the battery, this is done from the output wire to the engine body (ground) and should give you a voltage reading of 12.5-13.5 VDC. Any other reading indicates the BCR has failed and needs replacing.
3. To test the battery check across the poles. Again you should get 12.5-13.5 VDC. If you get a lower or higher voltage, replace ASAP or it will damage your BCR if it has not already.

The OEM battery for you engine has been discontinued, but we sell alternative batteries that will suit your engine.
