The Troubleshooting and Repair for On-board Charger (OBC) Thread

[Exhausted76]

Take a look at this post and the few following it, there is a pictorial of the steps to replacing the snubbers when soldering to the stubs is not possible.

Hi,

Can I please just check that the capacitors themselves are just sat in free space and are not 'mounted' in any way other than the legs connecting into the upper part of the board (N0/P0) as pictured (i.e. not connected to C122/C121).

Note: be careful when bending the wire leads of the caps to not break the "blend" of the ceramic/porcelain cover to the leads. Hold the wire with pliers so no force is put into the blend.

That is correct--no connection to the C122/121 solder joints (cover them with sealant such a Permatex Ultra Gray Form-in-Place Gasket FIPG maker, non-acidic calcium carbonate filler).

Solder your new caps directly in parallel to the N0/P0 solder junctions. The wire leads and held by the solder and the sealant acts as vibration damper and provides some additional support. They are just floating in free space as you say.

The side fence wall could be removed completely if it makes it easier to route the leads and make the soldering, just insulate everything to avoid any issues later.
