Hopefully you've checked the connections at pump, and connectors under
sink area. If so....

In my 81' air cooled, I installed a relay as an "isolator" between
starter battery and aux battery. Wire that supplies 12V for charging,
(B1  in your case) is connected to one side of relay, (voltage in)
then other side of relay (voltage out) to POS post of aux. battery.

IIRC, I installed a 30 A fuse between wire from output of relay to POS
post of battery but I would consult other users wiring diagrams in
archives before taking my word on this!!

I connected Blue wire to supply voltage to energize relay, and
remaining relay connection to ground. (my relay is in a plastic
housing)

I agree with Mark. There should be a fuse between fridge/water pump
etc. and aux. battery.

Ultimately the better way to supply 12V charging power to aux battery
is via a heavier gauge (#10) from positive of starter battery to INPUT
side (voltage in) of isolator relay. I did this, running wire through
protective conduit. The remaining wire that originally supplied 12V
for charging aux. batt. is now used in reverse to supply 12V to a fuse
at panel which in turn supplies 12V to house lights and radio.

Hope this helps.
