Our bow thruster battery bank consists of two 12 volt AGM
start/deep-cycle batteries. Monitoring the charge state of the these
batteries under the bed is a pain in the neck. To ease the problem, I
recently made and installed a battery monitor such that the voltage
and charging current of each battery quickly can be monitored without
taking the mattress and hatch covers off. If anyone is interested in
installing one of these please contact me for details.
A related issue was the negative terminal on the port battery. This
terminal suffered a partial meltdown due to a loose connection in July
2010. A repair allowed continued operation without battery
replacement. Unfortunately, during installation of the battery
monitor, a crack was observed across the face of the terminal. When I
wiggled it, the terminal broke off nearly flush with the top of the
case. Although the battery is old, considering the cost of a new
battery, a repair attempt seemed worthwhile. The repair worked – a new
terminal was successfully cast onto the old terminal stub. A load test
with the bow thruster confirmed that operation of the new terminal
under heavy load current is satisfactory. Please contact me if you
need details on the battery terminal repair procedure.
