Engine battery and house battery questions.
My coach sat for about 8 weeks. Went to move it and the engine battery was dead, drained, kaput. House batteries were fine, they were replaced recently with new deep cells. Anyway I used the bypas...

a while back, after i found the chassis-house solenoid relay part of the Intellec Bidirectional Isolator Relay Delay device (BIRD) was sticking ON like its predecessor also did, i disabled the solenoid. it is the upper silvery solenoid in the pic. i took off its small DC power wires and pulled out the 5 amp fuse. both batts are now isolated. the left large gauge terminal goes to chassis batt and the right goes to house batt.
the BIRD device is just behind the house batt which is accessible thru an outside access door. i ran a short wire from the left solenoid chassis terminal to a screw into the wood floor over the house batt. both batts are side terminal 'starting batteries' and about 9 mos old. when parked at home, i put house battery disconnect solenoid (lower one in pic) in STORE, open the access door, and remove the positive cable from the house batt.
about every week, i open the access door and read 12.75V on the house batt, but about 12.58V for the chassis. i connect an external battery charger to the screw and ground terminal of house batt and charge chassis at 10 amps/hr for 3 hre, at which time it reads 13.07V. a week later, repeat process, sometimes giving the house batt a little charge, as well.
batts are happier than anytime before when on the BIRD.
is constant trickling to 13+V better for batts?
i could pretty easily leave rig plugged in w/house solenoid in USE and use battery tender/minder in a 'cigarette lighter' DC port.
but does the 2005 chevy 6.0L have a live DC receptacle?
and, could it cause some other thing to blow a fuse?
