That "exciter" circuit from the panel to the D+ terminal just "kick-starts" the charging. Once the alternator is up and running, that circuit is not active until next time.

Theoretically (I'm not advising this) with the motor running, I believe the B+ terminal (battery +12V) could be momentarily applied to the D+ terminal to "activate" the charging circuit. The alternator would then generate voltage like it always does.

Of course that would still leave you with no instruments or warning lights.
For two 3 hour drives? Not me.

What kind of cluster work is the motivator here?
