[1983Cabrio]

My '83 cabriolet had a weird thing happen. The Tach started going haywire, jumping up and down. Then, all of the lights went dim, the radio went out when I stepped on the brakes, then the high beams stopped working. Yes, the battery was dead.

Now, my car's battery has been dying after 3 days of non use, so I figure it's a short.

Question - When I test the Fuse bar (with the battery removed) there is NO WAY it should have continuity with the ground for any reason, right? Except a short somewhere? No reason there would be ground continuity with the starter, or alternator? - I removed the fuse box from the body (in chance of a mounting bolt shorting it out) and it still beeps with ground...

How should I start finding the short? I'm sure it burned out the voltage regulator.

Thanks for your help, sorry for the long message.
