QuestionHi, I installed a GX670 replacement engine on my Wheel Horse and it appears that the engine is not charging correctly. Additionally, I seem to have small drain on the electrical system as the battery goes flat over several days. The charging circuit appears to be putting out about 12.77 volts. How do I check the rectifier and charge coil? I need page 5-8 and 9-4 of the shop manual, but am too cheap at this point to buy the complete manual. Can you help? Thank you.
AnswerHello Larry:
>>From your Description it Sounds like this Engine has the 3amp Charging Coil and Not the 20amp Charging Coil Under the Flywheel.
>>There are 2 Charging Coils Listed for this Engine.
>>One is a 12VDC/3amp Charging Coil (part #31630-ZJ1-003) and the Other is a 12VDC/20amp Charging Coil (part #31630-ZJ1-801).
>>The 12VDC/20amp Charging Coil has 3 Coils Connected together and the 12VDC/3amp Charging Coil is a Single Coil.
>>The Engine Block should be Drilled so Either Charging Coils can be Installed, Depending on the Engine Application and Amperage Requirements.
>>The 3amp Coil is Used for Powering Lights Only and will Not Properly Charge a Battery.
>>This May be the Reason for the Slow Discharge of the Battery.
>>Using an AMP Meter, Check the Amps that the Charging Coil is Producing before the Regulator (if Applicable).
>>If the Amp Meter Shows 3amps or Less, then
>>Remove the Flywheel and Inspect the Charging Coils.
>>If you have the 12VDC/3amp Charging Coil or if the Amp Meter is Showing Less than 15amps and you have the 20amp Charging Coil (usually has 3 coils and the 3amp is a Single Coil), then
>>You need to Replace either the 3amp Coil with the 12VDC/20amp Coils or Replace the 20amp Coils because of the Low Amperage shown on the Amp Meter.
