    Can you troubleshoot the electrical system with a wiring diagram.? If the answer is yes then need a Serial Number to identify the correct one for your machine.

    The yellow from the key switch activates the main relay. Turn key on and check for voltage at yellow, here. Screenshot_20191111-195110_Chrome.jpg

    If voltage is present on yellow with key switch on, test the purple (main power) on the same relay's large post when yellow is energized.
