This seems like the best spot for radio questions. My 1990 was a radio delete, but has the radio wiring harness, and the connectors through the door for speakers. A previous owner had some sort of radio installed - the radio was out when i got it, but there were still speakers in the doors. He had some... creative... wiring to get power to his radio using a spliced extension cord.
I picked up an RX-173 for a good price - the seller claims that it worked when he pulled it out of his vehicle - so i plugged it into the harness when i got it, but no power, no anything.
I'm more suspicious of my jeep's electrical vs. the radio, and am not sure of the best way to confirm where the issue is... the PO had snipped the speaker leads from the harness to connect directly to his radio, but i'm assuming i should still get power from the harness. The accessory power wire (purple and orange?) was also pulled out of the harness... but i'm not sure i'm getting any of the accessory power.
I've replaced all the fuses, but am wondering if the radio delete option didn't connect the harness to battery, or if i'm totally going down the wrong path. I'm pretty sure the PO didn't disconnect the power, given the somewhat rigged power that was hooked up previously.
Any tips on testing the power? I'm pretty new to the electrical side of things. I've got my multi-meter, but am not sure where to stick my leads...
