I had a similar problem in my 88. loosen the fuse panel and check the wiring behind it. Often times wires going into the fuse panel become dislodged and you lose power to various places. Also, do you have an aftermarket radio installed? If so make sure it was wired in properly not just hacked in there.

definatley a bad alternator. Check the cars voltage
with engine revving. It should be over 13. If its less, youralt is the most liikely problem.

Alt is good I have been on that road kinda just notices it apears to be ALL the stuff that will togogel on and off with the ignition switch, so what path would be the best bet to track? When sun light returns I will pull the fuse box and check the conection but I do have power at the fuse box (to all fuses) but none the less I will still check, keep feeding me ideas plz

There is a connector at the front left corner of your engine bay, if you have to service it removing the air filter box assists access. The connector is hidden right down in the corner and is a high probability area for corrosion and electrical shorts, melt down, and gremlins. Several wires in this connector, I respliced all seperatly and tossed the connector. Well worth having a look.
