OK, Here are some tests to preform BEFORE re-polarizing. 1. Confirm that the battery wire to BAT. terminal of the V/R has 12v dc to ground. This terminal is always powerd even if the key is off. 2. Remove the blue and yellow wires from both the S/G and the V/R. Check the wires for good continunity {zero ohms}. If ok, re-attatch both wires at both ends. 3. Start the engine and run it at FULL throttle. Using a jumper wire, temporarily ground the "F" terminal of the S/G to the battery or chassis ground. The S/G should charge at this point, and you should hear a definite drop in the RPM'S. If you have an amperage gauge, you should notice the needle in the charge position. 15 amps would be the max. charge out-put from the Delco-Rery S/G. This means the unit is charging, but it is an UNREGULATED CHARGE! NEVER leave your cub wired up this way! 3A. If the unit does NOT charge when the "F" terminal is grounded,{no re-duction in RPM'S is noticed}, the S/G is defective. 3B. If the unit DOES charge {RPM'S drop}, then the V/R is defective. 4. Then try your re-polarizing as mentioned above by other Members. The usual electrical failure on these units is that they will motor but not generate. This is caused by the generator FIELD COIL failing in open circut mode. This is info. that I have found but never yet had to use. Hope it helps!
