I’ve replaced my speedo recently for a working unit but it seems to read just below the correct speed. I’ve checked the correct speed with a sat nav but the speedo reads around 5-15 mph below the actual speed depending how fast I’m going. Reads 30mph when I’m doing 25mph, and 80mph when I’m doing 70mph etc.
I’ve carried out the speedo amplifier checkas per the instructions in the picture below. It failed the test keeping battery voltage at all speeds. Does anyone know where the amplifier is? And what the issue may be if it’s reading battery voltage continuously?
