Battery drain overnight

Parasitic drain. Check the net on how to check for. Since you know the circuit, should be fairly easy. Here is your dilemma. Checking the wiring is easy. If you see no problem there, removing the radio and having the radio bench tested will cost more than a new radio.

thank you "G". i think this is what's happening to mine. according to the info in that link, the issues they post is exactly what mine is doing.

No problem Sean, thanks for your business, its greatly appreciated.

BTW, the item relists with a different item number and URL, it is easier to search through the items I have listed rather than to keep reposting here and making a nuisance of myself. https://www.ebay.com/sch/newyorkbuyer/m.html
