Zongshen 200GY-2: Electrical System Resistance Values

SpudRider · 05-31-2013, 12:02 PM

When troubleshooting electrical problems for the Zong, it's best to measure the resistance values of all the electrical components.

Measure the resistance values when the engine is cold. You don't make any measurements while cranking the engine.

Here are the specified resistance values I have obtained from the TW200 and XT225 Service Manuals.

Electrical System Resistance Values

Spark plug cap resistance:
Both Yamaha manuals specifiy 10K Ohms

Ignition coil resistance:
Primary Coil: Yamaha XT225 manual specifies 0.56 to 0.84 Ohms
Secondary Coil: Yamaha XT225 manual specifies 5.68K to 8.52K Ohms

Pickup/Pulse Coil Resistance:
Both Yamaha manuals specify 656 to 984 Ohms

Exciter/Charge Coil Resistance:
Yamaha XT225 Manual specifies 584 to 876 Ohms
