Series 2 1000 volt insulation and continuity tester

[ex 2 Base]

I have a damaged Series 2 insulation and resistance/continuity tester, its the 1000v volt type in a large alloy case., with hinged lid over the meter. I would like to know how to dismantle the case and gain access to the workings. Also does any one have a circuit diagram and any thing else which MIGHT enable me to fix the device. Ted

HI Ted, from memory there were screws in the end cover that can be removed, also look out for a sealed screw or 2. The wax seal must be removed before the screw itself becomes visible.

Not sure if the "runners" on the underside also need to be removed to get the innards out.

I sold mane some time ago so I'm afraid I can't check for you.
I believe forum member Dave Moll has it now.

Thank you Ed, I've now got the case open, the screw heads were covered by lead inserts. I would now like a circuit diagram with component values if possible. Once I withdrew the meter part the every thing looked old but in good condition. I connected my multi meter on the DC range, wound the handle and got 7 volts on the output terminals. So it could be the generator which is faulty, as I'm not in need of a 1000 volt Megger I won't lose any sleep over it, but will keep trying to fix it, I like a challenge . I have a 500 volt one which comes in handy from time to time when testing motors for my friends. Ted
