Starter Solenoid

More Qs.

The solenoid has two connections. One goes to the + on the battery. The other goes to the starter motor.

On the solenoid itself is a 30A fuse. What exactly is the purpose of this? I know what fuses are for but what does this fuse do? Does it pop if the starter motor tries to draw more than 30A from the battery?

30 amps is not a lot for a starter if you think about a battery with at least a couple hundred cold cranking amps, it must be to protect the solenoid? That seems a lot to trigger the solenoid tho? Whats the starter to? emti

The fuse is for the rest of the bike's electrics. The bike's starter can pull a couple hundred amps, so there's no fuse for the starter motor.

There's a connection (big wire, sometimes red) directly to the solenoid from the positive terminal of the battery. No fuse.

On some bikes, like yours, the rest of the electrics are fed from this connection on the solenoid, and for the sake of compactness and convenience the fuse and the connection to the rest of the electrical system are housed in the solenoid. On other bikes, the fuse is somewhere else.

You may want to spend some quality time pondering your bike's wiring diagram.

You may also want to update your signature with the year, make and model of your bike.

Bwringer is correct, its exactly like that on my '03 xt600e, however, I think the stock fuse is around 20a

The above gentlemen are correct, the 30 amp fuse is the main fuse for the bike and most likely feeds the other fuses for lights, turn signals etc.
