Roger Chatfield 0 Posted March 16, 2015 Evening chums, quick one for you all. My volt gauge is under reading by about 1.5 volts, I've had a meter across the battery terminals and get 14.5v with the engine running but the gauge is reading 13. Now I thought that maybe it's just the norm but when I visited the 'Ox' to pick up my sunroof I noticed that his was reading the correct 14 odd volts. So, can these gauges by calibrated? Rog.
