Hi all, my '86 SDL has come up with a strange symptom; about a month ago it didn't crank after sitting at my parents for some weeks, so I jumped it (had no choice) and took it for a long drive (home). It's been fine since and I take it for a long drive at least once a week when I go visit my folks...drove it around town yesterday and then tried to start it today...and nothing.

I cheated and tried to jump it again since it's on the street. Starter initially clicked then all power disappeared from the dash cluster. I checked all fuses and the fuse on the OVP relay; all of them look good. If I pull out the OVP and put it back in the dash lights come on and starter clicks - then back to the same symptom where there is no power going to the cluster with key on. Same thing if I disconned and reconnect the battery (-) terminal. At one point during this, I hooked a voltmeter to battery and it gave me an extremely low reading of <2v which didn't seem to make sense...after disconnecting it briefly, I tested it again and it seemed closer to normal with a reading around 12v; however, I didn't get a reading of amps.

I am not sure if my jumping attempt fried the OVP, or if this is a bad connection in the ingition switch, or quite possibly a bad battery. Appreciate any thoughts...thanks!

Edit: I took the battery out - will take it to AutoZone during lunch tomorrow to get it tested so I can rule out a bad battery.
