Just installed the Hi/Lo set of Stebel Magnums on the Eldorado. On ignition on they are almost dead but come on when the engine is running. There is a relay which has come in the box. From the posts above I gather it is not needed as the circuit is fused for 15 amps. In this case do I need to put install the relay? What else does this circuit serve so that I know when to put in a relay to avoid an overload.
There seems to be a significant voltage drop that using the relay will help with (2014 Calif 1400 Custom). I installed my Stebels originally without the relay, and they worked great. I DID notice using them at night with everything lit, the lights will dim. A few months later, I was splicing in a USB socket, and decided to go ahead and add the relay that came in the horn kit since I had everything all apart anyway. Made a noticeable difference in the horn volume. Where they were just LOUD before, they make ears within 10 feet bleed now. And lights no longer change brightness at all. A good thing...
