Hi Andrew,
Sorry I didn't check this thread earlier. I have attached the wiring diagram for the Vögel IG38 I found on line somewhere. Doen't add much to what you already know, but I thought I'd post it for completeness.

Russell soldering was my first idea but not yet having seen it i'm not sure if the plastic the spades are embedded in will take soldering heat - many modern electronics bits melt as you solder them - D type connectors being a case in point! I'd also wondered about the numbers - the new one is 5 bar - it's only checking that a reasonable pressure is reached and no  pipe has popped off so 5 should be fine as it's not controlling the pump.

Matthew yes I had that in mind - always like to see causes, but with this one I want to make an adaptor so the I can pump it up and check it out of the pump before destroying it.

Mark, thanks for that - added to my Vogel library  :thumbup:

As long as there is no water present, Sulphur can't give corrosion issues.  A lot of the panic comes about when there is potential for H2O from either condensation or combustion products.

The replacement pressure switch arrived by post this morning, so I've fitted it using the brass adapter that I made.

Interestingly when I came to the electrical connections, one of the original crimped spade lugs had already fallen off and the second fell off when I touched it . The copper cable where it emerged from the crimp had completely corroded through! So I reckon that there is a good chance that the original pressure switch is actually fine. I must make an adapter up to test it under pressure.

Cutting the cable back and crimping on 'female spade lugs' I assembled it and slavered 'liquid electrical tape' all over the crimps externally, hopefully excluding oil ingress in future. Messy runny stuff to use !

Can't put it back in the oil tank until this gunge has set so later this evening probably.

Always good to find the smoking gun...

Seems highly likely that was the issue.
