I have a 93 stealth that has started to just die out. Radio and lights can be on or off, day or night. When it quits, no radio or lights. Starter just clicks like battery problem.After about 10-15 min it starts and runs fine for a day or two. Had bat checked - ok. Mechanic can't figure it out because it does not happen when checked.

Have You checked the resistance in the Positive Battery Cable going from teh Starter to the Battery? I had teh Exact same problem a few years ago on my '91, and I found out that the Cable had degraded so much that it had powdered when I cut the Coating open. Easy fix, took me all of an hour and $6.

Corrosion creeps down the battery cable , seems to act up more in the wet??
