Wilo Pump Capacitor Replacement

[Marko!]

Hi All, new member here.
I have a Wilo Gold RS50 pump fitted to a solar thermal system. I suspect the capacitor is faulty and wish to replace it. However, I cannot see the method to disconnect one of the capacitor leads (sited between the L & N connections). It is very tight and I don't want to damage the connection such that I cannot install the new one.
The other capacitor lead is held in with a clip and is easy to remove.
Any advice appreciated.

This is going to sound strange, but I am not sure. I was stripping the outer electrics and plastic parts of the various motors. Capacitors are off but I do remember cutting some of the cables.
Think some are soldered into a board.
Will take a look now.

Cheers

I have some of the black capacitors from old Wilos.
Looks like I snipped the ends of the wires. Think they were soldered into a board

I think that is most likely as I can't see a way to disconnect it. I would have liked to test the old one first but didn't want to take it off without having a replacement. I've ordered a new one now, so should be able to swap it soon. I'll post the outcome afterwards. Cheers
