Placing the voltmeter in-line(in series) with one of the battery cables and it's relative terminal(doesn't matter which one)and with the key off, the voltmeter reading should be zero. On tri-phase systems, there are three diodes in the rectifier and each diode represents approx. 4 volts. Therefore, drain readings of 3 to 5 volts would indicate a failure of one diode and readings of 7 to 9 volts, two diodes. Tri-phase systems use a combination regulator/rectifier ASM. and these are replaced as a unit. Drains can also be caused by by shunts to ground. These are best tracked down by isolating circuits, either by pulling fuses, or separating connectors(while watching the meter). All 250's and above displacment scooters are tri-phase systems, while it is my understanding the GY6 based scooters(125/150's)use a single-phase system. For these, the "at battery" tests apply,  some details(such as voltage readings and diode location and replacement) will be different. |
