1987 nissan 300zx electrical problem

I have learned that my 87 Z's electrical issues are par for the course with this model. Having the mess of electrical diagnosed is pricey, and often without result. One problem I fixed with the help of an Ebayer selling my same car...the many routes for water to get in often short things out. His had the same issue as mine, in that the rear brake lights provide an avenue for water. It took me several fixes to get it right. Hatch and t-tops also allow moisture to collect in rear well/tool storage, and corode things on the way. I still find shorts that drain my battery, it's an ongoing project, but I love a challenge!
hope this helps
