Refurbishment and Calibration on Smiths Voltage Gauge - Battery Condition
The battery status gauge I had was tatty, and 10V would not register and 12V read 15
poor old thing was a bit crusty and failing.
So time for a bit of a refurb. This evening was refurb time, so case stripped, recoated in zinc rich coating then a little lacquer
Then clean the glass
Chrome retaining ring had the black removed from it exposing some nice chrome so that was cleaned and polished and the inner rubber seal which had turned brick hard removed.
The actual black back drop faces a bit different, washed in WD40 much better, then cleaned off and will touch in tomorrow, especially the outer ring and movement
Movement wise looked intact and in extremely good condition. Gave it a rough calibration however given the type of gauge it is as much mechanical aaaaas electrical and registers not by a mechanical movement but heating the strip. So actual final CAL will need to be done when gauge is re-assembled.
Will cover that tomorrow
Yes i could have just bought another gauge but where is the fun in that
