[QUOTE="elsalvador182, post: 2972064, member: 576518"] I think i may have an electrical problem. I cannot get my 'new' used pioneer HU to power on. I removed the old alphine HU from my 92 sentra in which the HU radio was working and playing just not reading or playing CDs. Connecting just ground and power does nothing. I reconnected the old alpine to see if the pioneer might be bad. Now the Alpine will not power on either. How can i go about trouble shooting to see which part of the electrical system might be the problem? I have checked every single fuse in my car as well as both HUs. I should note that im also trying to get my turn signal lights to work and wipers. Wipers will only turn on if i put in the fuse. Once fuse is in they cannot be turned off. AC on/off button will not light up either. Today i replaced every single relay thing i could find with replacements from a junkyard; both under dash and under hood. I know this sounds like a relay issue but old HU was working fine with the other electrical problems before i removed it. Isnt HU wiring almost direct to the battery? Trying to avoid going to the shop.... thanks for any suggestions.... [/QUOTE]
