2MC CAPACITOR

Part No

RGM Genuine

2MC CAPACITOR


HEAVY DUTY LEADED HIGH OUTPUT CAPACITOR, A DIRECT REPLACEMENT FOR THE OLD LUCAS 2MC CAPACITOR BUT HIGHER OUTPUT.

THESE WERE INTRODUCED BY LUCAS TO AID THE STARTING AND RUNNING FOR BIKES WHICH WERE FITTED WITH ALTERNATORS TO RUN WITHOUT A BATTERY.

FOUND TO BE USEFUL ON ANY BIKE WITH OR WITHOUT A BATTERY AS IT ALLOWED STARTING WHEN THE BATTERY WAS FLAT AND GENERALLY GAVE EASIER STARTING AND SMOOTHER RUNNING.  FITTED AS STANDARD TO MOST BRITISH BIKES FROM THE LATE SIXTIES ON.

IT IS WORTH POINTING OUT THAT CAPACITORS DO NOT LAST FOREVER, IF YOU DO NOT KNOW HOW OLD YOURS IS OR IF YOURS IS THE OLD BLUE 2MC OR IF YOUR ALTERNATOR EQUIPPED BIKE DOES NOT HAVE A CAPACITOR THIS IS WELL WORTH FITTING

OUTSIDE DIAMETER: 35.2 MM

LENGTH OF THE CAPACITOR: 55.4

ALL "2MC" TYPE CAPACITORS ONLY HAVE TWO INPUTS, POSITIVE AND NEGATIVE HOWEVER ON SOME BIKES TWO WIRES GO TO THE NEGATIVE TERMINAL, THE ADDITIONAL NEGATIVE WIRE IS JUST CARRYING POWER ELSEWHERE, EFFECTIVELY USING THE CAPACITOR AS A JUNCTION BLOCK, SOMETIMES THE EXTRA WIRE IS REDUNDANT AS IN THE POLICE INTERPOL FLASHING LIGHT.

PART NO: 990737 HAS TWO SPADES.

PART NO: 990737MK3 HAS AN EXTRA NEGATIVE SPADE.  THE CAPACITOR IS IDENTICAL IN BOTH CASES.
