I bought 2 96 900 zxi for mine and my wifes anniversary and one runs great but the other the guy told me they put a new motor in it and went to start it but the battery was dead so they tried to boost it with jumper cables and he said it burned up the ignition switch. Ive tested the ignition switch and it is fine but When i push the start button its not sending fire to the sylonoid. I have tested the start button wire also with a tester light and it shows fire and i have jumped the sylonoid with a screwdriver and the motor will turn over, so i dont think the starter is bad. What should i check next or where do i start? Thanks to anyone that can help. Thanks again
