Sounds like you have a slow (high-resistance) short in your electrical system. Tracking them down can be a real pain. The best bet would be to have a mechanic find and fix it. If you're the enterprising type, you can begin going over it with a multi-meter. Or, if you want the easy/cheap way out, you just put a big switch inline with one of the battery terminal cables, and use it as an on/off switch for the car.

Just additional information on 85 Nissan 300ZX. The belt is breaking almost as soon as it is installed..

My first suspicion when I read this is that your air conditioner pump has seized..... This very quickly burns the belt in two... Either that or your alternator or water pump or power steering pump... You have to find out what doesn't want to turn..

300zx only has1st gear and 3 gear?

Your gears are stripped,must remove Transmission and open to see what is wrong,you can drain fluid and probley see metal shavings from gears.These types are easy to rebuild,but it's best to get a remanufactured one,everything inside will be new versus just replacing bad parts.I have a 85 nissan 4x4,replaced mine 4 years ago with a reman,and it still works great.I paid 700.00 for trans.,it's a 5- speed.Came with a year warranty and synthetic oil is used.
