it is a 2001 ds racer and i put in a new regulator and can not find any place it should be shorting out.
thanks.

 

Nobody has had this problem or knows what it might be.

 

check the light switch on the bars. it may have a short in there.

 

There has to be a short somewhere, does your tail light work when the head light is out?

 

How often do they blow ? As soon as you put in a new bulb , or does it blow them shortly after you replace the bulb ?

The reason i ask is that i had a 1993 Suzuki LT4WD 300 KQ that blew the bulbs in a very short peroind of time , however this quad had the 4 headlamps and would blow one and the other soon after replacement of the first one to blow ; it turned out to be the lack of using Di Electric grease on the bulb contacts and bulb sockets !........

 

i checked out headlight switch(looked fine)
taillight works
it blows them shortly after but usually the first long ride.

 

Do the bulbs burn out or shattter? What type of bulbs and whatage are you using ?
