Bukh buzzer rewire

[afterpegassus]

A short while ago I posted with an apparent overheating problem indicated by the buzzer. Some suggestions were followed and I thought the problem solved.
However on my return this week to the boat the buzzer made its presence felt after a few minutes of running. The engine is clearly not overheating and i can feel the thermostat working by the changing temperature of the manifold.
During my investigation I managed to break of the male connector on the sender when disconnecting to silence the alarm so that's another £50 gone south.
However, to the point : during searches of various various forums, I came across several references to the printed circuit at the back of the Bukh logo and its known unreliability. Mention was made of rewiring this conventionally. Has anyone done this and is there a wiring diagram to assist a person of average comprehension?

I have emailed you some manuals containing BUKH wiring diagrams [hope you have broadband!].

Before you shell out £50 it might be worth excavating the plastic around the broken terminal and trying to expose enough metal to solder a wire to. Then seal it up with Araldite.

Thanks for manual.
Tried the excavation route - something I am good at, but not enough meat to solder to. I also tried Belzona, but the contact was poor.
Broadband? Aye - great by the Tilly lamp.
