So my friend's got this Intramotor. The lights work, but the headlight in particular is very dim. It's getting juice, just not very much. The taillight is bright enough while riding, but gets very dim at idle. The brake light cables are disconnected from the brake levers. Could it be that the brake light is always on, making the headlight dim? Or is it possible that the previous owner installed the wrong coil somwehere? Or perhaps just a poor connection? The bulbs are all the correct voltage and wattage. Help!
