I have 3 Hella 4K lights on the front. Two Euro and one fog in the middle. I actually use them a lot. I had them on the other day. I turned then off for an oncoming car and when I turned them back on only the far right (passenger side) came back on. All the connections are as they where. No obvious wiring problems. I pulled the fuses at the relays. When I pulled the white #25 fuse the remaining light went out. When I pulled the blue #15 nothing happened (the right one stayed on). I changed the #15 and still only the far right light works. Obviously I did not install the lights and do not that much about the wiring. Any thoughts would be great | ||

Matt, Sine you checked all of your connections and they are tight and corrosion free (hint)...What do the bulbs look like? If you turn them on and off a lot, they can burn out just like any other light. There is a 50W on road bulb and a 100W off-road bulb available at the autobarn. Check out http://www.autobarn.net/hellah3.html for some replacement bulbs. Or do some research at: http://catalog.com/susq/hella/bulb_help.htm Whatever you find out Matt, please post it here. A lot of people talk about the Hella install, but hardly ever mention bulb replacement. Paul | ||

Any ideas on how to disassemble/ assemble the Hella 4000s to check? Any links with info | ||

check your ground for that individual lamp. it's one of the most usual culprits. | ||

I would agree with Paul and Jack that it sounds like a grounding issue or a bulb burned out. Try swapping the good light bulb to the matching other light and see if it will then work. That will save you some money on bulbs if that is not the culprit. Also, you mentioned pulling fuses. Were these in the LR Fuse panel or in a Hella harness? If they were in the LR fuse panel, then I would suggest checking to see if your lights are wired using the stock wiring. Not a good thing for the number of lights your running. I only ask this because you said you didn't install and were not familiar with the wiring. Further, you can open your lights, take a test light to the wiring in the light, and check the ground that way. If you test light works with a secure ground on the test light, then more than likely it's the ground, but I think if it were me I would start with moving the bulb from the good light to the other to rule out the bulbs. | ||

The sega continues. I hooked up a volt meter and there is no current going to either of the lights that are out. Like I said in my first post, nothing happens (light 1 stays on and the other 2 stay off) when I pull the #15 fuse on the right hand Hella relay (relay closet to the engine). This leads me to think it is a relay problem??? Yes, NO??? How would I check for a bad relay? Why are there 2 relays? I do not think it is a ground problem because the lights are grounded through the mounting bracket on the brushguard. That is all tight. | ||

Where are your relays located? Is there evidence of environmental damage; water, mud, salt, heat? Are you sure your fuses are not burned out or cracked? Are the Fuse contacts clean? If you are 100% sure your fuses are good, then.....You are on track by checking voltage output from the relay to your light. Now you must check the voltage input into your relay from your switch in the cockpit. This will determine if your switch is good or not. If the switch is good, and you are getting voltage to your relay; but no voltage comes out of the relay, then that is your problem. Susquehannah, Autobarn, and EE all sell the Hella relay. Good Luck, Paul | ||

Paul....from what you are saying, it's the relay. I know the switch is good because the 3rd light works fine. I changed the fuses. Why do I have two relays? One has a #25 fuse and the other has a #15. I think the bad one is the #15 relay. | ||

You have a relay for the set of two lights, and probably a relay for the single light. I would suggest checking the grounding. Take a test probe and tap the hot voltage at your lights output and then test using a ground screw under the hood. The ground may be my initial thought, but based on what you wrote I'm thinking that either the fuses could be blown and just not visible, or the relays are truely bad, but that would only make sense if it's the pair thats out. |
