Have an older 9500HR elliptical with a suspect alternator control board problem. Board number is A080-92127-C000. Display won't light up. Battery voltage is 6.04 VDC. Have 6 VDC on alternator control board (power control board), but no voltage at pin 4 on alternator control board, and subsequently no 8 VDC at pin 1 on the 10 pin connector at the display. Can you test and repair this board?
