70 series dead head unit (1 Viewer)

[Maccuscharlie]

So I let my brother drive my car and he left the lights on overnight. Battery died so we jumped it. Now my Sony Apple CarPlay unit won’t turn on and the usb charger port doesn’t have any power either. I didn’t install this thing so I have no clue how the wiring and stuff works or I would take it apart myself. Any ideas what’s wrong and how to fix it? - it’s a 94 kzj78

Check your cigarette lighter fuse, or any other ones. Also your fuseable links off the battery

Fuses seem fine, everything around the unit works fine including the cigarette lighter.

Most head units have a fuse on the back as well. Might have to pull it unfortunately to check that.

hello,

Sometimes jump starts and car alarms mess with the head's grounding. Check your grounds as well.
