Jerry, that is a 'bipolar&#
specific + or - lead.
If you want to use a replacement to test the original, get two electrolytics
of twice the capacitance of the original and wire them in series, that is, +
to +, or, - to -.
Voltage rating of the new caps can be the same or higher.
Thanks Paul. I will give that a try, but isn't + to + and - to - parallel wiring? I thought series wiring would be + to - to + to -
