Hi, I've had my GY-200 for a couple of years and up until recently it had never been used at night. I've just started a new job and I have to commute in the dark and the headlight and rear bulb seems to have a life expectance of about 10 minutes :(
I noticed the indicators flash more quickly at high revs a well so I changed the voltage regulator with one from a breakers but it didn't fix it. I found the ballast resistor under the tank and it reads 430k ohms so I guess it's ok.
Has anyone got any suggestions how to trouble shoot the fault and find out why the bulbs are blowing?
