HELP! electrical short?

hi

i just bought a '99 ZX7R and i love it

but now it has a problem
- every time i give the bike throttle it blows my fuse for my headlights

so i was thinking of checking the following:
- voltage regulator
- make sure the correct bulbs are in the bike

does anyone else have any suggestions or might know what exactly is causing this?

Sounds like the regulator is shot. Get it changed quick before it fried the ignition.

V. is most likely right, but before you spend your money take a few minutes to pull the tank & check your wiring for spots where the insulation has burned or rubbed through, or burning at the connectors.

bike's don't have alternators...they have regulators and rectifiers.

Are ya sure about that? I thought they had an alternator and a rectifier? (Alternator generates AC, rectifier converts it to DC and filters)

Check out this site for a manual:

The regulator/rectifier is in a heat-sink about 3" square. It is probably located in the tail section of your bike, attached to one of the subframe rails.....
