Question about JVC KD-HDR1 CD Player
I had my JVC professionally installed. Several times if I left my car sitting for a few days it wouldnt start, dead battery. I pulled the fuse that supplies only the radio (now the JVC) problem solved. Figured it was a bad JVC head unit and got a replacement under warranty. SAME PROBLEM. Unit plays fine but will drin car battery if left for a few days (3) shut OFF. Car battery is very strong, only a few months old. Can sit for a long time with zero trouble if I pull the power fuse to the JVC.
Is there some installation error which could produce this battery drain when the unit is OFF? Hard to believe I got two new head units with identical issues unless it is a design flaw and if it was there would be stuff on the net about it and I dont see any.
Any answers or clues greatly welcomed.
The problem is actually the wiring. Check the installation manual, I guarantee the "pro" installer took a shortcut.
There are two power wires (yellow & red +) and a ground wire (black -).
Now, black goes to chassis grounding point. Easy.
Yellow goes to a live terminal in the fuse block for constant 12V.
This retains the settings and clock etc.
Red goes to an ACCESSORY terminal in the fuse block (so key must be turned to at least ACC to allow it to be switched on).
But in the case of my car, the idiot who installed it ran the red wire directly to the + battery terminal. That's wrong, and will drain the battery.
Google for an installation manual, I'm certain your JVC head units will be the same procedure.

This HAS to be a problem with the head unit if the fuse ONLY goes to the head unit. Try this... Remove the head unit from the dash and un-plug it, but leave ALL the fuses in - If it STILL drains the batt, this is a problem with the circuit that the jvc is on, even though you think the fuse ONLY powered the stereo, it may go to something else causing the draw... I have seen MANY MANY cars that will list 1 fuse for the stereo memory, but if you trace the wiring you will find that circuit also may power cigarette lighter sockets, clocks, and many other "hidden" draws.
