I became frustrated and linked the pump to my internal PSU. It was running much faster than before and there was a leak in a tube connection. The pump isn’t working with the jump-started PSU either. I’ve got an air-based leak tester ready, but I’m tired of this.
It could be 12 - 3 = 9 or 3 multiplied by 3 equals 9. The number three should remain as 3.3v. If a 9 volt measurement persists, you must create a diagram of all wires, connectors, and pins. And after reviewing it, why is an external PSU used when testing for leaks?
Some devices are activated by a switch that supplies power when it is closed = ON. Power is cut off when the switch is turned OFF. Other devices operate through a more intricate process, starting with a short electrical connection (such as a push button) that triggers certain circuitry to turn the device on. However, pressing the button again does not shut it down. Disconnecting the power in a different way is used for turning it off.
In summary, if a "wrong MOLEX wire" was present, it’s unclear what consequences occurred with the circuitry.
The original wiring and subsequent connections remain uncertain. What connectors were used for the initial jump start? The pins in each connector are important. I believe something was damaged during testing, particularly if both power supplies were connected simultaneously. You should draw diagrams illustrating all wires, connectors, and pins involved—PSUs, pumps, fans, etc.
