We have a 1989 Itasca sun flyer. We parked it last year everything was fine, we got it out this year and it would not start. We bought a new battery it started not a problem I pushed the dual button to try and charge the aux batteries the thing died and we haven't been able to re-start it. Checked the new battery, replaced the solenoid , nothing, replaced the fuses, nothing, replaced the circuit breakers (all 5) nothing. I don't have any head lights, directionals. when I turn the key the coke, check eng, and brake come on but nothing else not even a click. Please help before my husband shoots it and turns it into lawn art.
