Thanks. I agree.
Hopefully they left the original wire and made a good splice to it.
I can't recall whether I could ever see the back of the ammeter from underneath - even with a mirror. Since everything is on the workbench right now I'm not going to be any help there. I *think* the only way to really see the ammeter posts clearly is to remove the dash panel. I'm pretty sure that's what I did when removing the panel. Lemme check my notes but I'm pretty sure I removed many of the connectors from underneath, but the ammeter once the panel was partially out.
