I've just found one of these Auto-Lab condenser testers (model 215) but it doesn't work so well.
I have a request for Mr Debe if I may. Is it possible to get the capacitor sizes for the 3 capacitors up at the top of the panel please? I can see the .27UF on the big sucker down the bottom. It was crook on our tester. The sizes of the other capacitors I cannot read.
Positioning is different but you may be able to locate capacitors relative to other items such as the coil looking thing that plugs in next to the valve. I see one is the little button capacitor in yours. It's connected between the valve and the plug in coil thingo.
