Installed Fog Lights-Not Working Kubota 500

[Tide1996]

Hey Guys,

I bought some small rectangular 55watt fog lights to go on my Kubota RTV 500. The instructions stated to hook directly into the battery, instead I used the winch's positive on the contactor lead and grounded the negative wire. As you guessed the lights would not work . The lights came with a lighted rocker switch. The switch lights up when switched on indicating power is going to the lights. So when that method didn't work I ran the positive directly to the battery as the instructions indicated, same results as above. I used my voltmeter to test and I'm getting power using both setups above. I'm thinking the lights or rocker switch was defective. I don't think the 55 watt lights would be to much for the 500, if so would it keep the lights from lighting? Any opinions would be appreciative.

Thanks!

If you are checking for voltage at the foglights and it is 12 volts with the lights connected, then they should burn unless your bulb is bad. No problem for 55 watt lights or more on a RTV 500!!

Probably a bad ground. Check this with your multimeter by using the OHMs scale. Also check the resistance across each light. It should be very low. If it is infinite, bulb is bad or connection inside light is bad.

Ground could be the problem Where do you recommend a good ground? Everywhere I looked has paint.

I used one of the big bolts to metal under the hood as my ground point.

If you are running a HOT wire to the lamps from a source why not also run a NEGATIVE wire back to the common negative of the machine. In this way you have a good power supply. The term ground on 12 VDC is thrown around in very loose terms. The chassis is the NEG of the system. When you power a light in a vibration mounted area you have to connect to the closest NEG.

Here is a pic of my additional running lights. These lights are 55 watt and the ground is connected under one of the large bolts under the hood (it's the red wire in the second pic) One of those bolts already has a large ground strap wire under it (it's the bolt in the far left of the second pic). Also found an unused wire under the hood that is hot only when the headlights are on. Used that wire to power the running light relay.

On a side note, I just installed the KFI 4500 lb winch in the pic too!

If the winch works, you should have an adequate ground.

The winch ground goes all the way back to the battery. The ground under the hood is only for the additional running lights. I would always run a solid ground from the battery for something with a high current like a winch!!
