Spent a bit more time getting a bit more sense out of the meter.
I followed your advise Dave and cleaned up the contacts as you suggested and now have two of the ranges working. One of the leaf switches was hardly making contact with the blade, so I had to put a slight set in the blade with long nosed pliers. The needle in all ranges was sticking slightly in mid range and I have cured that by removing the mirror glass first and then bending the dial plate very slightly and now all is good. I don't know what they made that dial from, but it is tough metal !!. One range to sort now, the X -100. When probes are shorted needle goes fsd. Not sure what is going on there yet.
I also have to make a top cover out of 16 gauge alloy and print out the label for battery connection.I have a decent one to scan and copy.
Mike.
