Look at that!, that big green cap in there is a replacement to the one in the can that I was talking about. Make absolutly sure that there is NOTHING connected to the lug on the original "square" cap in the can, if there is, its still shorting out and thats your trouble. Change that waxy looking thing, thats junk. Wax coated electroylitics cause lots of problems. If youve got a real electronics store (something I dont
Give them a try, they could have it. Keep in mind, barely anything today uses capacitors rated at 475 volts so dont be surprised if they havnt got anything like that in stock. As for your digital VOM, its kinda tricky for testing caps. Make sure your meter setting is at its lowest multiplier. Touch the two leads on the meter an watch for a jump in the digits then they will probably fall back down to "0" or close to it. Then, touch the leads to the capacitors while they are in the circuit. If you observe nothing, no changes in the meter, the cap is probably oK, however, should the digits start to move around, its shorted. As for voltages, set your meter to read out DC. Basically, an analog meter is alot nicer for cap testing kind of work. You might want to pick up a cheapy analog at the hardware store. They are generally those pocket sized ones and usually $10 or under. But anyway, the digital should get you through these tests.
Good luck!-Doug
