Problem is solved it ended up being a broken power strip in the circuit board under two of the relays an electronics place in town was able too fix it for 20 bucks and we are back up and running pump has 240 and the heater has 240 that you guys for all you help

I moved the white pump wire from the j14 lead too the j25 lead and nothing happened but then I moved it too the j32 lead and it jumped too life pump is running and the heater has 120 volts going through it the j32 lead is in the l2 side does that mean the l1 side has a problem with it

The burning on the main terminal is from me trying too jump the pump direct from the power source and when it kicked in it was back feed from some where’s

I had it on the neutral lead and I moved it to the j 14 lead that it showed in the wiring diagram it should of been on but now I lost all power too the pump

So I used the diagram you posted and I had the common in the wrong spot I moved it too the right spot but now I have nothing neither pump lead has any power they both read zero

I did the test you said tested from the low to the common and the high too the common when o do while the tube is running the high reads 123 Volta and the low reads 20 Volts at the same time I click the pump button too kick it too high speed and the relay clicks right back off tried it with the pump hooked up and in hooked and got the same readings when the pump turns on. It’s like it’s fighting it’s self like the power is drawing the pump slows down below are picture of the board and the whole cabinet it dosent have a wiring diagram but the circuit board is a mini max 1503d75b

The first two and the pump leads off the board the next two are the volt readings from the black and red wire too ground and the other reading is between the red and black the others are of the back of the pump and the start capacitor and the last one is the pump diagram not when I turn the pump on it kicks on but sounds like it has a super heavy load on the motor Boggs right down like it’s starving for power and then comes out of it and runs for a few seconds and quits

I am running and older Aruba spa last year I replaced the circuit board and this summer the 240v 2 speed pump melted itself together I purchased a new pump and installed it now when I turn the breaker on it turns on low speed for 15-20 seconds then shuts off after some time it does the same thing over again I have tested the power coming too the tub crossing the leads and it’s 240v I test the leads at the pump cross them and it reads 000 but if I check each lead on the pump separately it gives me 120 I had two relays on the circuit board replaced and still nothing when the other ump kicks on low it sounds like it’s starving for power or pulsing then it comes out of it but still stays on low I got the pump button but nothing happens thanks for all your help
