[R-390] R-392 Power Connector

[Osamu Hazawa]

Barry and Tim,

Thanks for the detailed and comprehensive explanation.
Actually, I have some "Quick Disconnects" connectors in my junk box,
and I was going to use them.
But alas, they are naked, without any insulation. So heat shrinkable tube
work is needed (I hate it!).

So, as Barry advised me, I'll try "Butt Splices/Connectors" or "Fully 
Insulated
Quick Disconnects". Any DIY stores might have them.

Yes, after I confirmed that the R-392 is up and running, I eventually have 
to buy
"that" connector for safety purpose and  a finished look.

Regards,

Osamu Hazawa
