I have 75 cb360t that keeps blowing the headlight fuse when the on/off switch on the right controls (which is unique to the 74-76 model i believe) is turned ON. It doesnt blow if the switch is in the off position. The bike starts and all other lights work, but when the headlight switch is turned on the fuse blows and headlight no longer works. Any experience with this type of issue.

Are you saying the headlight comes on and then the fuse blows and the headlight THEN won't work?

(does the headlight come on at all or does the fuse just pop immediately?)

Probably faster if you just phone....540-525-5199

No the fuse pops as soon as the headlight switch is flipped to on, so no the headlight does not come on.

Short is somewhere after the fuse, so unplug the Black with yellow stripe wire where it connects to the dimmer switch Black/yellow stripe wire (in rubber boot at left front /under the fuel tank)...
install new fuse turn headlight switch on.... IF fuse blows, problem/short is in the main harness....IF not, you are good to that junction, and problem is in the wire up the bar to the high/low switch, or in that switch itself, or one of the wires (White or Blue) to the headlight itself.......

Let us know what/which cause you find.....

What else shows on that circuit if you look at a wiring diagram? Horn? Brake light? Anything else?
Have you removed your headlight bulb to see if the fuse blows without it in the circuit? A simple diagnostic test light replacing your headlight bulb may help you figure it out.

Has it always done this or has someone had it apart recently? Apparently, the power path to the switch is ok, somewhere between the headlight switch and the light is the problem. Pull the screws out of the switch cluster on the handlebar and check for bare spots where the wires enter the hole in the handlebar. If things are ok in the handlebar switch check inside the headlight shell.

Your wiring is OK to and past the "ON" switch ( including the switch), and at least to the fuse box.....
Any problems/shorts prior to the fuse box would blow the main fuse, NOT the lighting fuse.......
Please follow my 3/03 post to track the problem further......
OR, Phone while at the bike with either a meter or an electrical probe tester...... 540-525-5199
