Wondering if anyone has any photos of solder joints that can fail during/as a result of monkeying around with the solenoid board whilst engaged in the O-ring change?

When re soldering do you guys suck the old solder off and replace it or simply melt and re-wet?

And yes, I do have the Mr Vanos kit, but have ordered the factory rings to compare...Will post died by side photos when they arrive.

You just connect with solder the pins that are next to each other on the small board on the solenoids...
That's it...

SO am i looking for a broken run on the board or a wire to post type of thing?

Never seen the Vanos board, however, I have dealt with a lot of broken and cold solder joints. Not sure if the original solder used is lead free solder, if so, it usually has a higher melting point and tends to be a bit more brittle that lead based solder.

Usually I will retouch/rewet the solder joints using a rosin core based solder. Usually lead based as this is what I have a lot of on hand. At times I will use to liquid flux if I think there is enough solder on the joint already or if there are closely spaced connections or terminals.

Have seen many problems when boards are run in either a wave solderer or IR solderer and the heavier/larger terminals tend not to heat up enough to get good solder flow and you can have cold or weak solder joints.

here's a picture of the board

should be the joints right off of the solenoids
