We own a 34HT Mainship. I’m having issues with my Intimidator AGM 8A8D (1450 CCA) battery that supplies power to the bow Side-Power SE100/185T (740 AMP, SAE 1425) thruster.
The dedicated battery is located in the engine room and supplies power to the thruster with 4/0 cable? (no markings but measured 3/4” across).
This is the second battery that cannot hold its charge any longer. The first new battery was installed in 2016, the second battery 2019. Can the battery be damaged if I use the thruster too long? Over 6 secs...during strong cross winds.
The bow thruster will perform perfectly with a new battery. But after time the battery under performs. We installed a new Pro Marina 1250 50 amp 3 bank charger back in 2019. With correct settings. Hoping that this was the problem.
I checked all terminal connections to make sure that they were tight. I came across the bow thruster positive battery cable that connects to the 500 AMP fuse plate. The terminal was burnt but tight. Possibly a bad terminal made connection. (See attached photo).
I contacted Side-Power. They stated that “if the thruster motor is not getting good voltage, below 10.5v it will Pitt the contacts in the solenoid”.
Back in 2019 I had the thruster motor rebuilt due to the brushes being worn.
Any suggestions would be appreciated.
Thanks,
