@gunrunnerjohn The ammeter leads that came with mine are the same as the white and black voltmeter leads in your picture above. The difficult to read (even with a magnifying glass) label looks like 28AWG, but diameter measures more like 30 ga. I was hoping to make these meters a permanent part of my layout's control panel, but am concerned about continuously running <= 10Amps through these wires while feeding power to the trains on my layout.
I'm wondering if you may have substituted bigger wires (blue and yellow) for the Ammeter input leads in your test box. If so, did you assemble your own connector or buy pre-made pigtails for this? I'm happy making my own, but if possible would prefer not to dismantle and rebuild the included pins first. Any recommendations on either pigtail assembly or individual parts (connector housing and pins) you could make would be greatly appreciated.
Thanks again, Steve
