70 up charging system upgrade question

With 70+ VR the mount holes aren't the same. I really didnt want to drill new holes on firewall. I made a bracket out of aluminum. Installed for the interim for more tests. Still scratching my head.
Got the idea for bracket from @fishy68
ThankTracy!
Continuity at all grounds, even with battery unhooked?
So jumped the ign switch terminal, at the red batt and blue wires. Both at switch terminal.
Battery static 12.40V
Results
Ign2 to ground 6.16V
Ign1 to ground 10.45V.
Does this mean a 2V drop in ign1 circuit?
Thanks

Battery static is 12.20 V.

IF "IF" you are measuring this AT the igntion switch IE the battery wire going to the switch, AND WITH the key in the "run" position, then the switch or the connector is your drop, or at least a whole big bag of it

To fully test this, round up a couple of male spade/ flag terminals and make a short jumper wire with no14 or so. Disconnect the switch, and jumper the switch connector from the red batt to the blue. Go out to the ballast and see if things improve
