Signal fuse keeps blowing - 2000 Yamaha XJ 900 S Diversion

Disconnect all of the turn signals at the lens assembles. Plug in the fuse. If it still blows, you have a wiring problem and will need to trace the wires to find the grounded wire.If the fuse does not blow, then replace the assemblies one at a time until the bad one shows up. Also check your fuse box to see how much damage was done to it. Look for melted wires. Hopefully it did not do much damage.

Does the fuse blow on both left and right sides,or just blows randomly or as soon as you put the new fuse in?
Does it have tilt steering?I would check the wiring in the steering column to start.

When a fuse keeps blowing everytime you replace it that means there is a short circuit along its cable. Check the flasher cables or call a car electrician to do it.

The parking lights, dash lights, turn signals, and hazard flasher should be 4 different circuits.
So you would need to know exactly what that fuse protects, then look for the short to ground.

most likely caused by a short, could be any were. start with the light assembleys remove it and clean any rusty or coroded spotspull all bulbs clean and or replace .auto parts stores sell an electrical parts wash about 9 to 14 $ . spray as needed let dry and put back together.if it still blows fuses its some ware in the wire s , could also be at the turn signal switch or the brake switch . you would have to get it to blow to figure out witch one it is and witch one it is not example put in new fuse then keep putting on the brakes if not blown then keep doin the turn signal then check to see if blown

try putting in a 40 amp fuse in. its worked for me in the past

I am thinking you might have a electrical short in your steering column

Replace the signal Relay thats your problem.

It sounds like the fuse is doing what it is supposed to do, and burning out when there is a short circuit. Check the wiring from the fuse block back to the lights and pay special attention to the trailer connection.

This is more than likely caused by a Bad Turn Signal Switch Housing inside the Sterring column. The one that the Handle is attached to and Wraps around the Sterring Shaft on the Inside of the Column.
