Hi there JeepForumers. I'm trying to address a nagging problem with my radio. This after-market deck was installed before I bought it, and it seems to be lacking a constant power source. That is, every time I turn off the car it 'forgets' the time, which CD track I'm on, EQ setting, etc. I'm assuming that's because the installer screwed up the wiring.
From the deck instructions (Jensen MP7610) there are four power-related wires coming from the deck:
1) Power antenna (dark blue) - currently unconnected
2) Ground (black) - currently connected to chassis
3) Memory/Battery (yellow) - 'Connect to battery or 12 volt power sources that is always alive.' This is currently connected to the fuse box above the clutch marked 'Radio' (see photo link below)
4) Accessory/Ignition (red) - 'Connect to existing radio wire or radio fuse'. Currently connected to the purple/white wire coming from the stock Jeep radio connection bundle. This purple/white wire seems to be the 'Car Radio Switched 12V+ Wire' according to online sources. There is also a red (or purple) wire (and of course a bunch of others) coming out of the stock bundle that sources say is the Constant 12V+ wire.
I'm guessing it's a problem with 3 or 4. Would a tripped fuse (the orange '5' in the photo below) cause a problem with the constant power? Or alternatively, has the accessory/ignition wire from the deck been connected to the wrong wire from the stock radio bundle?
Any suggestions are appreciated, this is my first foray into my Jeep's electrical system.
