i have been working on a 660 that a guy jacked up the wiring on. first there was not power going to the key switch, so i replaced the reverse sensor and the other sensor on the bottom of the motor that has a ground on it, then replaced the starter relay, and that fixed the problem. had power to the key switch and it would turn over. i unhooked the battery put the rear plastics back on reconnected the battery now when i press the start button the red oil light just lights up and does nothing??????????????? i have checked all the connections twice, could the cdi be bad? anyone ever had this problem?
