The Tester came with all the documentation including a cct diagram - all the 'short' warning neons are fed from the 170v supply via 100k resistors and go directly to the slide switches so either the resistor has gone low or the slide switches are dirty - I will clean them with contact cleaner and check the resistor - not sure sure what more can go wrong with those,
