Bit of a long shot but has anyone got a circuit diagram for a Megger Foster OTS 60PB oil breakdown tester. Ours has gone 'breasts skyward' and I'm trying to fault find. It'll go through its self test but as soon as it tries a HV test it resets. Even at just 1kV it resets as if you've turned it off and back on.
