Still cannot figure out why I don't have low beams.

[scubachris]

So I have been hunting this problem down for a while.

Background...one day I was driving and my lights stopped working. I still had high beams. I thought it was the steering column selector since I just added the H4 headlight setup. Changed out the column selector no dice. So I start to trace power. I am getting power in but not out on low beams. Hi beams are fine. Figure it is the relay so I go to Napa and buy two. The relays aren't the same but low and behold I have dim lights. The problem was brights also came on. So I order the original Flosser relays and still no dims? How is that possible? Is it the harness itself? Where am I going wrong?

Also, If enough of us pre-ordered, do you think painless would make a Fiat wiring harness?

Thanks

If you are sure you have relays in your headlight circuit they are something that was added by a previous owner. Some of the relay modifications were/are sold by the Fiat vendors and some are fabricated by the cars owners or mechanics. So unless you have some sort of a diagram for the relays it is hard to know exactly what you should look for. A common way to install the relays is to unplug the driver side headlight bucket connector located near the drivers side ground spider located under the hood on the fender well. The cars side of the connectors is used to operate the relays. I would look there for 2 wires one is gray/black and the other is green/black. They are the wires from the lo and hi beam fuses in the fuse panel. I would check for voltage on those wires. If you dont have voltage on the wires there check the fuses in positions 3,4,5,6, they are the headlight fuses. The power for the headlights comes from the ignition switch to the headlight switch then to the hi/lo beam switch in the steering column. From the hi/lo beam switch they go to the fuses. @ of the fuses are for hi beam and 2 of them are for lo beam.
Are your headlight relays mounted under the hood or are then under the dash?

Thanks for the reply. I added Autoricambi's head light upgrade. So I have a power wire coming out of the alt, goes to the relay/harness, from there goes to the lights. It completely bypasses the ignition and fuse box. Also has a ground wire.

I am not familiar with their kit. Somehow your Lo beam relay has to be told to energize and power the lo beams. There are 2 connectors coming out of the steering column. The connector with 8 cavities has a gray wire with a red trace on it. This wire is the lo beam wire out of the steering column. Can you fine that connector and measure the voltage on that wire in the lo beam position of your Hi/Lo switch? In a stock configuration that wire powers fuses 5 & 6 which are the lo beam fuses. The lo beam wires out of the fuses are gray with a black trace for the drivers side headlight and solid gray for the passenger side headlight. Some of the headlight relay kits use these wires after the fuses to control the relays. If your relays are mounted in the engine compartment this could be the case. Just in case check fuse 5 it is the one most often used to control the lo beam relay.
