65amp wiring/trouble shooting

i have a rare ammeter in my car only 1300 made. and i successfully fixed it usuing fibre board, the kind used in valve amps to stop you experiencing death at 600V DC
and a range of the top hat insulators used on the ground/heat sink tab on huge power transistors

this allowed me to insulate its metal bar part from the gauge case
and allowed me to use the original mounting studs nuts and washers to mount it back in the metal gauge case with the studs insulated from the holes they pass through.

this kind of thing

obvioulsy spend some time getting the right size i just looked for pictures to illustrate

ideally you walk into an old style electronics shop with the ammeter in hand and demonstate what you want to do and the guy/gal behind the counter should help

otherwise mail order, you end up with a pile of parts that might have worked but are "just" the wrong size.... :)

a little bit of filing and drilling may be necessary
and a blob of locktite when needed goes a long way to provide peace of mind

use spikey washers also.
the orginal nuts on mine were brass and the spikey lock washers seem to be steel

mine is a VDO branded gauge made to chrylser specification in Australia so may be subtely different
