I need help figuring out why my off road lights are not working. They were working about a week ago and now they don't work. I have the power wire connected to the battery to a toggle switch. The power wire has a fuse on it but if the fuse was blown the light wouldn't go on on the toggle switch right? Then I have the toggle switch grounded. Then I have the white wire going to the off road lights which are LED and have all of the lights grounded and have regrounded them twice since the first time they were not working that was the problem. I even tried a different toggle switch but that didn't fix the problem. The only thing I can think of is the fuse is blown on the power wire but like I said the light on the toggle switch wouldn't light up right? Please help me figure this out!!!
No actually, the toggle switch may illuminate. Try checking the fuse.
hi, sounds like the present your lights furnishings are pulling is greater suitable than the swap or wiring can cope with. i could propose looking out the max amps the swap is rated for and changing it with one double that quantity. a greater effective (and safer) decision is to twine the lights furnishings right into a extreme modern relay under pressure out directly to the battery with extreme modern twine. Mark.
Assuming that the fuse is between the battery and the switch then I would say the switch is burned out. The switch could still light because different contacts in the switch are used for it. Try by-passing the switch and see if they work.
The light on the switch will be on if the switch was wired before the fuse. You see what a fuse is is a safety device. If there is too much current (amps) flowing through a circuit the fuse will blow. Its considered a fusible link or weak link. The fuse is the weakest link in a circuit because it will blow before any damage can be done to any switches, wires or electrical components. So this is what you do.First check the fuse. If the fuse is blown you need to re-wire the circuit. But before you rewire the circuit you need to first find out how many amps are running through the circuit. To do this use Ohms law (Volts/AmpsOhms, Volts/OhmsAmps and Ohms X AmpsVolts). Your bulbs should have an Ohm rating. If not get a multimeter set it to ohms hook up the leads to the bulb and this will tell you how many ohms are in it. Then take the ohms of all the bulbs in the circuit add them together then divide that into your battery voltage. To find your battery voltage simply set the multimeter to volts positive lead to positive battery terminal and negative to negative. If you need any help doing this find a video on youtube it will show you all the steps of how to use a multimeter and Ohms law to do the math. The reason you do this is to make sure that you are not going to fry anything. Don't go and start putting bigger and bigger amperage fuses in until one doesn't blow all you are doing is making the switch the weakest link in the circuit and this will blow next. After you have figured out the amps and know its safe to re wire, your circuit needs to be wired like this; Positive of the battery, Fuse, Switch, Lights, Ground. This is information right out of the book. I am a drive-ability tech and deal with electrical systems and ignition systems daily. This will work out perfect for you.
