radio will not work even with the key on and the fuse is fine. also if battery is left hooked up overnight, wont start but, if I disconnect the batterie and reconnect it it starts fine.
Dear chuckll-- Something is obviously draining your battery. Electrical problems are hard to diagnose without being able to use testing tools. Since minor electrical problems can become major ones with the slightest mistake, I suggest you let a professional mechanic have a look at it. Good luck from Bovan.
