From master switch, jumping from 11 power to 13 and 17, pumps run. Bad switch?If you were measuring 24V at the cannon plug with the switch on and none of the pumps were running and then you put 24V to the pump directly from the battery and both pumps ran, then either the cannon plugs weren't making a connection or you have a bad connection inside the control box that is not allowing enough amperage through to run the pumps. Go to the TM and check which pin on the terminal block in the center of the rear wall of the control panel is powering E2 and E3, you'll see it's TB5-7 from there the 2 wires go through the J2 connector on the back of the control box, pins E and F. Trace the circuit with you're meter and reverify you have power. If you still have an issue you can run a jumper from TB5-7 to one of the pumps and if it runs I would suspect a bad connection at J2.
24v on terminal 11 and 25. All other points are dead on S1. Master switch. Is master switch bad?
