Hi, do you have a wiring diagram for your scoot? I don't have the Agility 125. Looking in the Agility 50
there is only one thing it could be - regulator/rectifier. I've been reading up on this lately and they
regulate the AC as it gets to the rectifier so both AC and DC are controlled. Without that the voltage
will get too high and blow bulbs. When you change it fix all the blown bulbs before starting as it's
sensitive to load. Did you change the headlight wattage by any chance? Or add extra lighting? You
cannot do that on a system like this one...
