[PSUBS-MAILIST] MK-101 Connectors

[David Colombo via Personal_Submersibles]

Hi Alan,
With the blue globe male fitting into the top of the shaft, there would be
no twisting of wires based upon one of there videos I watched on how to
install., I Thought that I could use a flat blade connector and sleeve
receiver from the subconn, to mate to the MK wires and  I would not have to
push the wires much into the shaft. Its amazing that this information takes
so much energy to work out the design, You'd think subconn, has come across
this question before since its what they do.


Best Regards,
David Colombo
