Air Horns vs Electrical Power

I've replaced my alternator once and don't want to do it again. If I put air horns on the bike am I risking frying anything on the stock electrical system?

I put a Stebel Air Horn on mine and as long as you use the Relay that comes with it there is no difference in the power draw than the original horns. And the air horn will absolutely let someone know you are there. It was an easy install.

Adding a few accessories on our bikes is actualy better for the charging system then adding nothing. The excess power is being used instead of being bled off by the R/R, which adds more heat to the R/R and shortens it's life span.

Unlike an alternator a stator constantly produces electricity and what ever is not used is has to go somewhere.

Lance, this poses an interesting question for me. I've changed out my tail/brake light to LED to reduce the electrical load on my bike. Plan to do the same with the front running lights/blinkers. Am I actually causing my R/R more potential damage rather than helping my electrical system out?

Kinda. Most folks add LED's to save power so they can runs something else...like driving lights or heated gear. But I would not go as far to say that you are "causing your R/R more potential damage". If you have relocated your R/R you have already taken a step to eliminate "potential damage"...

Perhaps you should use that extra power for something cool eh?

I swapped out all my bulbs with LEDs too and tossed in an 80/100w headlight bulb. I still have the ole wet cell battery; haven't checked water levels in it since last fall (?) and my VM still shows anywhere from 13-14 in ridiing conditions. The only time I see it dip below 12.5 is at idle and when the cooling fan comes on. Once this battery goes tango uniform I'll toss in the AGM that I got last fall.

As KM said, If you have relocted your R/R it will incerase the life span. The less power the system needs the more the R/R has to bleed off to ground and the hotter it will get.

This has been an interesting thread. I thought I needed to go LED so more power would go to charging the battery. That's my concern. If I'm just damaging my R/R by reducing the load then what's the point? Might as well stick w/ conventional lighting.

Just FYI, you don't want to go more than a couple weeks especially in this time of year without checking your water level in the battery! If the battery fails, it can take the rest of your army with it sometimes. You especially need an AGM battery!

Good responses. I'll definitely add an air horn if it's helping my bike out.
