3. Test pins 2 and 3 of the battery connector for a minimum of 6.1 VDC.
4. Plug battery connector back into power control board.
5. Measure VDC between test points 7 and 12 of the power control board for a minimum of 6.0 VDC
6. Test pins 1 and 2 of the inductive switch connector while pedaling. VAC should increase with RPM.
