on my battery isolater, the top post leads to the positive on firewall to battery , then to battery,
middle post leads to wiring harness which i assume leads it back to alternator, the bottom post feeds towards to the big red cable that i think feeds the rear battery, same cable which used to have insulation issues.

after charging battery for a short bit i connect it back up. then measure, from battery ground to all 3 terminals i have voltage. little low on battery post but it was not on charge very long.

i use boost switch to start, then measure again. also all measured against battery ground. the middle one which i think is alternator has close to 19 vdc on it (bad regulator?) the top one, battery positive is still a little below the 12vdc.
the bottom one is also at the 19 vdc, which i assume is feeding voltage to rear battery.

couple questions,
is regulator external to alternator or internal,
why would the lead to rear battery read the 19 vdc if it had not had a chance to over charge yet, all input appreciated, i assume this isolator is wired properly , or atleast i have not changed it.
thanks bgk
