Stereo Not Working after Exhaust Header Install
Hello everyone! First post on the forum, how exciting!
Anywho, I have done some recent work to my 91 Base XJ. Over the weekend it included: APN Exhaust header New 703 swap for injectors Brown Dog Motor Mounts O2 sensor (yet to be installed, trying to find time to get under there) After my first startup there was no power reaching my stereo unit. It is a Kenwood KDC-BT362U. I did do the PCM reset method shown on https://thexjguys.wordpress.com/2012...injector-swap/ to reset my Adaptive Memory for my injectors, but I fear that touching the terminals together may have shorted something out. I have checked my ground, and previously had to run another constant 12v cable from the battery to my harness (before the swap, everything worked fine). My fuses are good (I have no acc fuse in my fuse box but i have two fuses: one inline with the constant 12v, and a fuse on the back of the stereo unit itself). Having done these repairs, one would think that it wouldn't affect the stereo considering that I removed the ground before doing any work. Any suggestions? Any advice would be greatly appreciated! |

Please elaborate. Where is your radio grounded, and when you say, "my harness", do you mean the radio harness? Or something else? Where did you get your constant 12v?

Sometimes people run these backwards or join them together, and then things get confusing.

Or perhaps Murphy is just being really mean today and this is coincidence! It's been known to happen.... |

Please elaborate. Where is your radio grounded, and when you say, "my harness", do you mean the radio harness? Or something else? Where did you get your constant 12v? Do you have a switched 12v going to the unit, as well? Most modern radios require that. Typical setup is 12v constant to provide the main power and to keep memory alive, and 12v switched to tell the unit when you have the key on or off. Sometimes people run these backwards or join them together, and then things get confusing. That's certainly a reasonable assumption (I would make the same assumption), but the facts appear otherwise. It's possible you shorted something to ground during the process and were not aware of it. Or perhaps disturbed some wiring and were not aware of it.

Murph!
