My right turn signal blows the main fuse every time I try it.

So far I've cleaned everything inside the bulb compartment. Made sure everything was making good contact back there. I bought new plates/spring/wire things that the bulb makes contact with. Bought new bulbs. Made sure nothing inside the compartment was touching the blinker wall.

It's time to ask for help before I go broke buying fuses. Thanks.

Interesting!

If you remove the headlight and lift the grey wire from the flasher unit

( power to switch)

you can use a meter to read the resistances to ground on each side

as you switch from one to the other



Bulbs will give a low reading so best remove them too

the idiot lights are on flying leads IIRC and easily disconnected



with all bulbs out of circuit you should get a high resistance reading

when the switch is in the RH position

If you dont, you have a short in the cabling, lamp holders or switch



The black multiway connector carries the cables from the LH switch gear

if you open that and test between the light blue an green wires from the switch

you should get very high resistance in all cases

If you dont you have a short in that area



Now test between the Light/blue and ground on the connector going to the harness

and lamps

if you get continuity, the problems that way.

Disconecting the lamp wires locally and testing in turn may help point the way

Good luck!

I'm concerned that you are blowing a 30 amp fuse, when there is a 10 amp one for the flashers that should blow first. What this means, I'm not sure. You can substitute a 12 bulb in place of the main fuse and see it it lights when you turn the right blinker on. You don't have to replace fuses then. If the bulb is bright, start working your way back from the signal and wiggle and tug on every wire. If the bulb goes out, you have located the problem area.



What Reg said will also work, but I think he may have a European model in mind.

Blue, where does he say 30amp? edit, nm, he says main fuse. Yeah I'd think switch as well......
