The Universal Mobil Connector UMC charge cable (MC240) was a step up from the 120 VAC 15 Amp yellow charge cable allowing a charge up to 40 Amps.
Unlike the yellow charge cable, this UMC charge cable plugs into a split phase 240 or 208 VAC outlet, and will charge the Roadster at a much faster rate than the 120 VAC 15 Amp charge cable.
As these heavier charge cables age, wire connections in the plugs and sockets sometimes loosen, and heat up and char the plug/outlet combinations. The custom Roadster charge connector is durable, but also has issues at times and quite repairable.
The two options for repair of this higher capacity charge cable are:
1 – If the problem is in the connectors, a replacement is necessary, we pre-tin any stranded wire connections into the plug/sockets for a longer lasting connection.
2 – If the problem is in the inaccessible potted and sealed contactor housing in the middle of the cable, we replace the electronics with a new Level 2 NACS charge cable which achieves the same 40 Amp charge rate with new hardware and electronics. Considering these cars are destined to be collectible, we preserve the vehicle’s collector value and maintains OEM integrity by using only the Tesla branded Level 2 Charge Cables instead of numerous aftermarket options.
