hella lights wont come on

[akfisher]

my d-90 came with hella auxiliary lights above the windshield that are wired to the high beams. they worked fine until last weekend when i noticed that they no longer come on with the high beams. there are 4 lights and none of them come on. high beams on headlights work fine. i checked the in line fuses and one was blown and i replaced it but still nothing. any ideas on trouble shooting? how do you check if a relay has failed? i didnt check the lamps themselves because i couldnt believe all 4 would go at once.

I would trace the wire and check connections. I would start with the wire that connects to the high beam switch wire and if it isn't that, start checking the rest of the connections and wiring for a short or broken wire.

If they are hooked into the headlights there has to be/should be a relay for them. Relays are just switches and they wear out. Find the relay, bet thats your problem.

My Hellas did the same thing..found out the wire got wrapped up in the stearing under hood and mangled the relay and wires beyond recon. Probaly not your case but relays do go bad and are an easy fix..any autoparts store has. Just make sure to mark what wires goto each post on your relay before disconnecting them less you want to trace all of them down. All post are marked.

found 2 bosch relays in engine compartment for hellas, appear to be wired to each headlight. is there some way to check the relays and see which one is bad before replacing both?

Just direct connect past the relay and you'll know if it lives. You can get cheap ones at auto parts store. But you might like to have a spare anyhow, they will die (even the Hellas). It could also be the ground wire.
