Am attempting to map out a pretty simple through hole PCB. It's the
central locking controller for late Rover SD1, and the complete unit NLA
as NOS. Made by Kiekert. Basically, two standard micro switches, a SPST
relay, and this timer PCB. The idea being to write a repair article for
the car club mag.

The PCB is potted in a blue material. Soft, and does cut off quite easily.
I'd guess something like PVC. But not sure. Removing it where it has
moulded round the components, a bit more tricky with a knife.

Anyone know of a solvent that would make it easy to remove - without
damage to any of the components or markings on them?


Very likely it's polyurethane resin or PUR...

This is supposed to remove it, to some extent...
