I have a 4.3 Volvo Penta V6 engine and I'm having starting problems I have a brand new battery a brand new starter and solenoid and a new 90 amp breaker the boat started fine before I installed a new shift cable. I have power to all gauges on the dash and what I am experiencing is when I turn over to start the engine all power shuts off immediately and I have no power whatsoever once I disconnect the battery and connect it one more time all power comes back I can't figure out why the starter is not engaging can you help me
