Hi John,
I understand now
Okay, if you number the spade connectors from the top 1-4, then 1 and 4 are the red power leads from the esc, (1 is connected to 4 underneath and the broken connection should be connected to the one you thought
wow that's a lot of 'connect's). 2 and 3 are the power leads to the motors and are connected 1-2 and 3-4 via the fuses. The black's don't need this separation so are just split from the blue wire from the esc.
As the fuses are rated at 20A it may explain why the Tamiya connector gave up the ghost.
I see various connectors have been mentioned as replacements, well if you ask 10 modellers what they use you'll probably get 10 different answers
Any of the 4mm bullets or 4mm blades will be okay
they're all rated at around 60+A
Mark.
