Bought these, one for battery input and one for output.

 Paul, Two of those look like the style of meters that were fitted to vehicles in the 60s and earlier. The Weston one looks like it could be earlier. Mostly meters of that age did not use shunts, they were built to not need them. The condition of them looks like they are that age. They were not precision instruments and will possibly have not lost much accuracy (not that they were all that accurate when new.) They should give a fair indication of the currents in the circuits but you will need to use fairly heavy wire and mount the meters fairly close to the battery.

 Yes Peter, I agree with your thoughts. I will use them for testing purposes for a start. I am still a little weaker after my hospital trip so doing some thinking and may get to the van in the next day or so. Thanks.

I might just wire them across my DC master switch for a test.

Aussie Paul. smile
