Not knowing which fuse is for the fog lights I believe I would have to check all of them. You could be having a problem with the switch or the wiring. I notice on the video above your headlights have to be on for your fog lights to work. I would check the wiring to the fog light plug and check for voltage. I would also check the wires on back of switch and see if you have voltage from the fog light switch.
I just had to change the connectors to the horn on my Chrysler 200 because corrosion/bad connection.
one wire will for high beam
one wire will be for low beam
the last wire will be ground wire
as fog light have only one beam you can use the low beam wire and parallel wire it to the fog lights
that way you have the head lights still and the fog lights as accessories correctly wired according to regulations
how to do it simply-- find the low beam power wire ( light switch on low beam and power at the light bulb check ed with a multi meter set on volts
solder , piggy back, or double plug in a connection into that wire and run one wire to the left fog light and one to the right fog light connect each fog light to an individual ground wire and connect those wires back to the ground wire for the main lights
Now having done that simple addition to the lighting system another problem has come up
The wiring will now be too light to carry fog light current and or the light switch will burn out
To over come this problem, the circuit needs a relay
fit a relay on the bike and now run the low beam wire to a terminal of the relay
run the other terminal wire to ground
this enables the relay to operate when the low beam is switched on but at this will not switch on the lights yet
now you have to run a heavy gauge wire (fused at the battery) to one of the power terminals of the relay and from the other power terminal to the connection for the fog and low beam lights
Now it all works switch on the high beam and no for lights
change to low beam and the fog lights come on as well
All nice and legal
Of course if you don't care about being legal just buy a 30 amp toggle switch and run a fused wire directly to the switch from the battery to the lights and then to ground from the lights
You will know that the generator / alternator for the bike will not be able to run the fog lights with or without the main lights so what will you have achieved
Ryan, Does the fog light indicator on dash light up when you pull out the fog lamp switch? Also, Are you aware the fog lights won't work when high beam is on?
Check the light bulbs themselves. If those are still good, (don't touch the glass on the bulb), then check all your fuses. Chances are, the foglight fuse is linked in with something else.
It's an electrical problem(you knew that)STEP1:check for voltage with a DVOM(voltage tester) at the fog light fuse,if current here switch is good,then problem is after fuse(make sure fuse is good). STEP2:check for power at the fog light ground (the fog light ground is bolt and nut that holds the unit up)if you get power at this end,make sure both light bulbs are good they might be a"series system"like x-mas lights if one burns out the other doesn"t work.
Most fog lights turn off when you put your brights on. Check their operation in normal mode first, if they turn off when you turn your brights on... this is normal.
To disable this you need the wiring diagram for your car, you will have to cut 1 wire to be able to have all your lights on at the same time.
hi disconnect your fog light switch if this doesn,t knock them off you need to find the fog lights relay and replace it as the fog light circuit is shorted best of luck yates210456
