Supply voltage
During a fraction of a second, when starting a trim tab motor, the current is much higher than normal
and the supply wires, fuseholder and battery should be in a good condition. This is important when
replacing mechanical switches with electronic equipment. Check the voltage supply by manually
operating the trim tabs. If the supply is weak, the ACS will restart and flash all the indicators twice.
