Yesterday I was driving on the FWY and all of sudden my head unit stopped working, I had the music on, loud, and it just died.
So I started from the fuse in the front bay, changed the 10amp fuse, didn't help, then I pulled the head unit (Alpine CDE-9870) and replaced the mini 10amp fuse in the back of the head unit, didn't work. I inspected the connector & wires and they appear to be in good condition. I don't think that's the problem.
Since I have a similar head unit in my TL (Alpine CDE-9872), I pulled the one in the TL & put the 9870 in the TL, it worked...damn, so I put the 9872 from the TL into the 98 V8, and it worked...great...I then swapped them back, and the 9870 started working in the Lotus as well, but only for a while, after I messed with all the set-up (setting the time) I pulled the key & hooked up my battery tender waterproof (not sure if this has anything to do with it) because I had the door opened while working on it. Just before I call it the day thinking I got it fixed I wanted to check & see if it works in the Lotus just to make sure, and it does not turn on, I swapped the head units again, and now both don't work in the Lotus, but they both worked fine in the TL. I tried the reset button, didn't help either. I'm not sure what the problem is now, can someone help me? Many Thanks...
