Any thoughts, ideas, suggestions or comments would be most welcome.
The control box
switches off the power to the motor
if the motor
gets overloaded or if it thinks it is overloaded. There may well be a fault in the wiring
causing extra resistance such as a corroded contact. It may also be a component failure on the PCB. I had that problem. With mine I found a blown varistor witnessed by a glob of insulation
that leaked out of it (a blue rectangular component with a little screw on it). This was measured to show an incorrect resistance reading. I sourced a new one using the part # on the component. 10c only. Desoldered the old and resoldered the new. Works fine now. A new control box
is what Lewmar
said I needed. $1000+ Ho ho.
