I don't believe the posters ammeter has one. These are permanent magnet moving coil meters. I believe it is OK to use because of what I stated in my edited post. The only wire is the coil wire around the needle shaft. This is 24-30 gauge probably. Regarding burnout danger: Wire not affected by the increase to 12V but is affected by current. Current is now lower (1/2) due to 12V conversion.
I believe the current is passed to the coil thru opposing springs at top and bottom of coil. So they carry current also. I will apply the same no-burn reason.
The YES still stands as well as the ammeter vendors not supporting 40A or modern alternator outputs. Recommending voltmeters.
