Now that's most enlightening re the hole at the back. I saw a small paper patch and didn't disturb it, thinking it was an air pressure equalisation breather with anti dust filter ?
I didn't put any resistor on as generally in or out the instrument is a pig to plug on the leads. In the end it was done almost entirely by feel and a mirror to ensure the correct pins.
Squeezing the lead brass slip on connectors in pliers though risky did make them stay on and until the recent creeping lower readings I was stupid but happy with it.
Clearly now in receipt of your latest intelligence I will remove the gauge and peel off the rear aperture paper and see if I can adjust it.
Might not need a new one now & saves me over £100 !
Though as you comment it really needs to be compared with something else reasonably trustworthy. If it can be adjusted it's back to borrowing the plug triggered tacho.
Many thanks and I hope you too resolve the errors.
