I just picked up a sun mdt 50 distributor tester at the spring flea. Any suggestions before I try to fire it up and run it? I see a "capacitor kit" offered on the net. Would this be a smart thing to replace before putting power to the machine?, Does anyone have a pdf of the repair manual?
Well I bought the capacitor kit and installed it. (mark from paramount distributors was a great help with a detailed article for the install).. The distributor spins and the flash tube is functional now. I need to get my dwell and TACH working now. Mine had the mercury cell for the tach and a d cell for the dwell. Anyone see an issue with using a power supply from an old computer(resisted to 1.35v and 1.5v) to work in place of the old batteries? The schematic shows the batteries are used to "buck" against a 6v supply to cause the meters to read. I was just wondering if this would be worth it?
