Before I saw your message I bought a CD player for an auto (non-marine). It had an additional wire for accessory that I have seen before when wiring cars but didn''t make sense on the grounding bar for the boat. I tried to install it from 9pm to 1am this morning. I spent 2 hours on the phone today with the manufacturer (most of it on hold). Long story short, I went back and bought a marine CD player by a different manufacturer and hooked it up the same way and it worked first time.
Question: Does a marine CD player have anything special that allows it to be used with the grounding bar? Or is a boat identical to a car installation since you ground car radio''s to the chassis instead of the block?
BYW: The second CD player also had this additional wire called accessory.
Thanks again for your help.
