Well, I bought a Juicebox 40* through Costco online. It happens to be the NEMA 14-50 plug model. Using the same 14-50 plug and Tesla J1772 adapter mentioned in my first post that the Mustart 40 mobile charger uses (and fails), the Juicebox worked successfully with a nice green light at the Tesla charge port.
So I guess that means I likely had two unrelated issues: 1.) Old (circa 2012) Voltec mobile charger is not compatible with my Feb.2023 TM3 in both 8 & 12 amp modes.
2.) Mustart 40 A mobile charger (Date stamped 20210706) is also incompatible.
Thanks All for the advice & troubleshooting ideas.
P.S. * Being in Connecticut, my electric company offers a $500 rebate on only two brands of charger; one is the Juicebox.
