Okay I'm frustrated, tired and confused and that's probably why I need help. On my Zenith 10S668 there are two electrolytic caps that I need to replace. C19 & C20. Of course they are in one can originally and I am replacing them with seperate caps. If someone could please take a moment and look at the schematic here on NA and tell me which side of those two caps are the positive side. The original cap has a red wire, blue wire and a black wire. On the old cap can it says red=20mfd 450v, blue=20mfd 450 volts and black is common. I know how it's wired now and it's not clear to me which side of the caps are positive. Thanks sooo much!!!

:NA lists the 10S668 as 10S699. Little typo I guess.

Johnny,

The plus of each cap connects to either side of the choke coil where the red and blue wires from the old capacitor went. The negative (this is the wire on the capacitor that connects to the metal shell of the capacitor) leads of the two replacement caps go together and connect where the black lead of the original cap went.

Johnny, if you are trying to identify the polarity of the new caps, Radiodoc gave you one way, others include arrow side of body usually pointing to negative(-)end, the end with negative usually exposed metal, positive end has some sort of isulation material with lead in center, by nature of manufacturing process the insulated disk is crimped into can so positive end has ridge around it (or groove depending on how you preceive it).

:Thank you radiodoc and planigan. Polarity of the new caps wasn't a problem. I just couldn't see how they installed into the circuit. The old red and blue wires I left hooked up in the radio to tell me where the new caps would connect. I just wasn't seeing it for whatever reason. So thanks much again. Answered my question perfectly.

Of course, disconnect the old capacitors.
