At the weekend I installed a new bow thruster, 2 new batteries and a BatteryProtect 220A.
The bow thruster does not work, I just get a clunk from the solenoid. If I bypass the BatteryProtect, the thruster works fine.
I was expecting the BP 220 to work OK, it has a peak current (30 seconds) 600A, and the 6HP bow thruster has peak current 530A, fuse 400A, and would only be operated for 5-10 seconds at a time.
I could swap the BP for a contactor, but all contactors seem to require a momentary switch, and my fuse panel has on/off switches for each of the 3 battery banks, which I'm reluctant to change.
What are my options:
1) Is there an easy fix?
2) Parallel another BO 220
3) Installing a pre-charge unit?
TIA, Gary.
