CA, the previous solenoid pic was from 2011 when i was already wondering about a fluxing voltage field of the two batts. i was urged to replace the isolator solenoid. this is the completed replacement today. there was no notable difference before/after switch.
i listed several 'as it should be' things in attempting a clear picture of state of switches when i observe 2 weird results:
1) engine alternator charging chassis batt alone handles house DC, and
2) the spooky 5 sec where non-charging chassis batt could nevertheless power house DC
Chris' explanation makes perfect sense w/r my BIRD setup
but it is things like 2) that i detect w/ my voltmeter, and as MEXICO says, causes my hail to fall out.
i am gonna just stop taking readings, i think. i know that posts of such results is a real turn-off.
thanks, guys.
