I have a 2014 20SL. When I put it in reverse, honk the horn, or turn on the docking lights my stereo and Garmin shut off which are wired into the accessory switch. Voltage seems to be pretty low, barely 12v. The resettle breaker for accessory was a little flaky so I replaced it. No change. Replaced the voltage regulator. No change. Stator test good at .3 ohms. Any ideas?
 
How old is that battery?
 
Do you have dual batteries?
 
Just because it starts good doesn't mean the battery can handle the draw of all the equipment once running. You should be seeing 13v while the motor is running

Putting in Reverse?? That should have No Effect on battery or current draw. Makes me think throttle control is shorting something out in control box or under engine cowling. Is your ignition in the controller or separate? Plus the batteries are getting up in age too.
 
Ignition is separate and only 1 battery. I'll try a new battery and see what happens.
