Hi everyone! I have an '86 Z that's been sitting for the last eight years or so, and I'm trying to get it fix up. I have it running, but I can't get the digital dash working. I've searched to forums, and it seems the most likely culprit is the power supply, but I didn't find any good information on testing it. The fuse seems good (back wiper works). I've tried re-soldering the pins with no luck. Is there any way to test the power supply before ordering one off ebay? They're not cheap, and I would hate to order one just to find it wasn't the problem. The dash was working intermittently before it got parked, and now the only lights that work are the warning lights at the top.
