Ninja Ewok

Hey just got my first RX7 and have been enjoying this forum so I decided to join and post. Got an '88 Convertable RX7. So far seems to have minimal - no rust and runs great. I am unfortunately having a short somewhere in my electrical system which causes all the switches to work on and off. Radio loses power, idiot lights and clock loose power and today top down didn't work but up did. Also wipers don't kick on and windows need new switches. Fun times ahead for me!!
