One issue with the "Molex" connector is that is is not a Molex connector. It is a Japan Standard 6 pin power plug and there is a difference in the sizes of the connecting pins. This is one reason people have problems with these plugs so often. That and time and wear and tear takes? their toll.
I have made adapters to replace the 6 pin radio side with Anderson Power Poles and that would be a good answer if someone would step up to produce them.?
I have seen numerous instances of low power due to bad connections and voltage drop under load.?
Basically a pretty Mickey Mouse application of a small diameter pin and socket that easily loses tension with heating and removal and reconnections.
If you replace the pins look for the correct pins and not the "Close enough" Molex pins and sockets.
