I have a Bad Boy 07 ZT 60 Inch Z Turn that started to have a battery drainage problem. Replace the battery and starter solenoid, after a week would need a jump. Now will not turn over. Battery is reading good, solenoid good, starter good, check safety switches that read good, switch relays around and no change, can hear the starter relay click when turning key, and the deck motor still has power. What could be the issue, bad wire/connection, faulty switch/relay that could have a good reading., etc?
