I installed a new radio, worked fine. Week later I tried it again and radio had no power. I thought it was the radio, bought a new one and installed - same - no power.

Checked fuses, all good but int lights/radio clock fuse has no power to it. Radio fuse has power in and out. Gray connector at radio shows pink wire no power, the red/white wire next to it has power. Traced int light/radio clock fuse to an orange fusible to red/black wire. Red/black wire after the fusible link is good and has power.

Would radio turn on even with the radio clock/int lights with no power?

I’m really lost at why the radio won’t kick on…

(pink wire doesn’t light my tester, but red/white does)

Highlighted fuse has no power to it. Traced that wire by fusible links and the black/red has power.

Two fuses highlighted across have no power (I don’t have power door locks).

 

Bump. I found out that the 12v feeder into fuse 14 (int lights, radio clock) drops voltage with a fuse is installed. The branch wires are pink, one goes to the time delay relay and the other two for radio and int lights(?). When there is no fuse, the black/red feeder has constant 12v.

 

Follow it back to where it gets power from. Sounds like a bad connection.

 

Im testing the feeder wire (12v source from the bulkhead). It has 12v when there is no fuse connected. When I bridge the connection to the pink branch wires, voltage drops on the feeder.

 

Yeah, I get that. Trace the feeder back to where IT gets power.
