[QUOTE="Targa4now, post: 4875008, member: 598682"] [IMG]//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif[/IMG] I ran the ground wire to the battery this morning and observed the same issue! (Currently both 12V power and ground wire are connected directly to the battery.) When the problem occurs, everything is operational and I'll be listening to my ipod via aux input cable (for example) and then head unit dies like there is no power. Then the unit turns on and then dies. This goes on with no distinct time intervals. All when driving key in the on position. No memory loss cuts-in-and-out is the best description. As far as the wiring goes, I've reproduced this issue with no speakers (or antenna for that matter) connected so I'm pretty sure it's not a short in those areas. I AM NOT using the switched lead currently. I tried running the switched power from the ignition and ran switched and constant 12V leads to the same source. All three wiring configurations give the same result. Although I changed my voltage regulator last year I think this issue my be related to either my alternator and/or my voltage regulator. My best guess is that my charging system periodically delivers a voltage spike and the head unit shuts off as a protection measure. I'm going to hook up my volt meter and see if there is any correlation. Advice please!! [/QUOTE]
