I have a 86 rx7 n/a. the electrical is starting to act up. I lost parking lights first. now i don't have any gauges in the dash that work. the climate control stopped working.the starter also just clicks a few times before it will start the car. the radio turns on half the time. I do have brake lights and turnsignals and headlights. all this was working until the car had to sit for six months. PLease help wit any ideas. I checked all fuses they are good. Is there any relays? and what might cause this probablem. i have replaced the headlight switch and wire harness.

 

Bad positive wire?on the battery.
Check and clean your connections,on the battery,the connection(ground) on the top starter bolt on the engine side)..clean and inspect the wires going to the engine bay fuse block.
Oh,and replace the Illumination fuse,Room fuse..Under the dash,by the Driver's kick panel(it is tucked up in the Corner.)
