Lost all power to head unit in WK2 Jeep Grand Cherokee, help!

[LittleLebowski]

I had everything working on my new Alpine ILX-207 and was putting it back, now I have no power whatsoever to the head unit, I can’t find any blown fuses, and I’ve reconnected the yellow, black, and red wires multiple times.

Do you have a multimeter or 12 volt probe to check power on those wires? Start there. If there is power remove and reinsert harness fuse.

I can’t seem to get more than 2 mV to the yellow wire, but I can’t find a blown fuse.

I can’t find any blown fuses at all, but my multimeter tells me I’m not getting power to the head unit from the main connector.

Does you cigarette lighter/charging supply work? That is usually tied in with the accessory fuse which powers the yellow wire.

Solved it, finally. There is a radio.head unit fuse hanging off of a battery cable in the battery compartment under the passenger seat. What a pain to find, it’s not common knowledge. Thanks for the guidance @1aespinzoa much appreciated.

Now I need to track down which cable from the Jeep is the antenna cable, I’m an idiot
