Well I have power at the radio, display reads "SP ERR", replaced power amp fuse ( #4 10 amp) left side works, still no right side, then fuse blows againg this morning. Any ideas?

 

Sounds like wires are touching,pull the head unit out and inspect wiring,it's grounding out causing fuses to blow..

 

I may need to do some more trouble shooting but here's what Iv'e found so far. Practically nothing, when I pulled the head there was one loose wire (black w/ blue stripe) stripped about a 1/4". I first thought it went into the #1 slot on the gray connector since that was empty, (thats for a mute). After nothing happend when I put it there I pulled it back out and the left side starteed working again, so I just capped tapped it off. After looking at some schematics it shows this to be a ground, (how is it possible for this to work at all w/o ground?) Anyway right side is still in-op, RR, RF and tweeter, Im thinking maybe it's the choke/relay since its the entire right side or maybe a bad head.
All advice and reccomendations are much appreciated and welcome.
Thanks Matt.

 

It's a PIA,you might pull the door panels and quarters off and check wiring there,You never know..............
