Was sleeving the pumps when I realized the wires were to small to do properly. Soldered on some 20 awg wire instead of the 22. First pump went well enough.
Second pump unfortunately did not go well at all. Upon pulling it out I noticed the soldermask was missing in parts and the trace was lifting up and broken. Not sure how it was still working (maybe it wasn't?).
Cleaned up up and tried to repair the PCB but it would just short out. :(
Now I don't really need two pumps, so I could drop down to a single pump w/ no affect on performance. I'd just lose the redundancy. I also have replacement PCBs I could install, but I'd lose PWM which is important to me as I like my quiet I can make the pumps run.
And I'll throw in a few pics of my crimper and stripper.
