Test method for BDI andMotor Controller on 2001 GEM

I have a 2001 GEM and it has a reconditioned motor controller and 7.5HP motor. With power on the BDI only illuminates the three small indicators at the bottom of the gauge. No power for motor at all. 72 /12V convertor has been replaced with recall one. I’ve checked connection between BDI and MC, seems OK . Is there a way to test either BDI or MC voltages to BDI, looks like there should be 12 V (across red / black) and 72V (across green / whit) is that correct, if so I ave zero on both? :eek:
