courtesy/clock fuse-weak battery
I put a new radio in my 84. when I hooked it up everything worked, until I turned on the radio , then it blew the courtesy/clock fuse. I unhooked the antenna and then I could turn the radio on without blowing the fuse(just no radio reception). Now my battery is weak(been on a charger all winter). I assume it's a short in the antenna causing both problems...thoughts? Anywhere specific I should be looking?

Antenna relay is supplied power by the CTSY/CLK - the RELAY? Possible...
Do you have the FSM?

No FSM, but I do have a wiring diagram. The old radio was original Bose with Bose speakers. New radio is Delco cd with Pioneer speakers and I ran new wiring to the speakers. I used a wiring harness to hook it all up. How would I check the relay?

There's a possibility the new head unit draws enough additional amperage over stock to warrant a 5A step up in the fuse. Did the antenna operate as normal before the swap?

new fuse?
JM2cW...if stepping up the fuse works just check by comparison between 2 wiring diagrams to make sure the original wire is heavy enough to handle the increased current flow so you don't heat up the wiring.
Like I said JM2cW

One problem could be is that the wiring harness was meant for a bose radio

Take a look at the specs on the original and replacement radio's. See if they're the same or not. If it's pulling more power than the circuit is designed to handle, you might be able to wire up a new relay controlled circuit. Fused sufficiently sized wire from something like the wiring junction under the hood. Run it through the firewall and using a SPST relay, use the fusebox circuit to energize the relay to in turn complete the circuit to the radio. Not difficult and safer than just putting in a bigger fuse.

The bose speaker amps are powered from the clk/ctsy fuse. If the pink speaker power wire is shorted somewhere after your installation which eliminated the speaker amps, this could blow the fuse. I would suggest removing the speaker power relay, so this circuit is depowered.
In the RH kick panel, reach over the top of it, and you can pull out an inline connector. There are two pink wires in it. The antenna control is the smaller one, next to the lt grn wire. With a good clk/ctsy fuse, radio=OFF, use a jumper to power the small pink to the orange wire in the same connector. The antenna should go up. Remove the jumper, the antenna should go down. If this test is OK, the problem is with your radio connections.
