T&T: Bow Thruster

[Chuck and Susan]

Doc, Have some one at the battery with a meter and check the voltage drop at the battery as the thruster is engaged. Next remove and thoroughly clean all wiring connections including at the circuit breaker. Re-attach and be sure they are tight. Do the voltage check at the battery again. How is the batteries for the thruster being charged? Are they up to full voltage to start with? Chuck
