No need to pull old can.
Cans are one to four sections, each a separate cap.
All the negative leads go to the can part. Each cap is marked on the
bottom with a square, triangle, half moon & slash. You see that
stamped into the can also. And it matches the manual.
To test hang one in parallel thats of similar value in mfd & the same
or higher in voltage. Use clip leads to do it. Match + to + - to -
If that fixes it you can cut the wires off the bad section & put the
right value in.
