Aux Light Wiring Question

[Brian McVickers]

Hi,
Ok, Help me find what I must be missing!

I have mounted two aux lights.
I also have mounted a relay.
From the relay there are three sets of wires:
- Two wires running to the battery +/-
- Two wires running to the lights where the like wires from each light join together with the +/- from the relay.
- Three wires going to a switch. Blue, Red and Black. The switch is on/off toggle with a red indicator light.

With everything connected I toggle the on/off switch - the red indicator light illuminates and the relay makes a click noise but the aux lights don't illuminate.

I tried bypassing the relay and took the +/- wires from the aux lights directly to the battery. The aux lights work.

Then, with the relay back in the system I tried changing the order of the Red, Blue and Black wires connected to the on/off switch. The aux lights never illuminated regardless of the combinations I tried and eventually one of the combinations caused the 30amp fuse, which is inline going to the battery, to blow.

So, what am I missing?
Could the relay or on/off switch be bad?

Thanks

Brian

Usually the relay only switches the positive leg. (scratch head smiley)

Should one of the wires from the lights be grounded, or ran back to the neg side of the battery, and the two wires from the relay be the switched positive 12vdc??

Thanks,
Well, the relay is part of a wiring loom that is already put together.
- one set black and red already with loop connectors on the end for the battery.
- one set Blue, Black, Red already with spade connectors on the end for the on/off switch.
- one set Red, Black, both bare ended to, I assume, connect to the corresponding wires from each light.

I could try to run the + from each light to the Red from the relay and the - from each light to the neg terminal on the battery for ground?
