SuzukiSavage.com - Disable headlight while starting?

DaveLKN YaBB Newbies Offline Posts: 41 Lake Norman NC	Disable headlight while starting? 06/08/10 at 21:00:55 Anybody know of any mods that can be done to the Savage that will shut off the lights when the starter is engaged to improve starter performance? Sure would be a nice modification if it could be done easily. It would help prolong battery life as well. Ideas? Possibilities?

easy enough to do if u have a wiring diagram. Just connect power to lights through a normally closed relay. Then splice power from push Start to relay solenoid and there ya go. The power to lights will be cut while pushing start button. I dunno how much this will help starter performance or battery life, but that's how I'd do it. Also make sure not to cut power to any ignition components or bike won't start.

I just wondered if someone had done this already- I had searched high/low for something along these lines that could be done without whacking up the wiring harness. I don't know why I thought this would be a hot mod- I was working with a marginal battery this evening trying to decide if the 'new2me' Savage needs a new one, and noticed that it would probably have fired if not for having to juice all that illumination while spinning the starter and energizing the spark all at the same time. Oh well, if it ain't broke- I'll try and fix it.

Thanks Verslagen- I'll search along those lines.

Further, anybody??

As james may said above - a automotive relay with normally closed contacts will do the trick. I found one which I believe runs fog lights.

I just close my eyes & pretend its off. Somehow, thers this nagging feeling that its not true, but as long as I dont look & prove its on, then I can feel better. I know that sounds odd, but thats the very philosophy the dumb masses use to hide from the things happening in the world. Most still have no idea how bad the fed reserve is, or how nafta went thru 7 what its done. People stupid enough to have supported nafta when it was happening should never vote again.. seriously,

Reply #8 - 06/09/10 at 13:30:05 How about using the kickstand switch to operate a relay so if the stand is down the headlight won't come on, stand up closes relay & turns headlight on.

I think a fog light relay will use normally open contacts., closing when switch is on.

The simplest way is to tap the starter button to the starter relay.
This tap will activate a new relay to cut the ground of the headlight.

push the starter button the starter goes and the headlight is cut.

However, I still like the idea of having the headlight cut when the kickstand is down. To do this, I'll have to try out a couple ideas. Concerned that taking advantage of the sidestand switch may interfere with it original purpose.

Yeah, but when you turn high beam, it kills the fog lights. I think that's what it was for, not sure.

Reply #14 - 06/10/10 at 06:05:37 IIRC, kickstand down provides a ground. That should be an easy thing to tap off & use. Add a ground to a normally Hot relay & instant energize,, as long as its a normally close set of contacts, then theyll open. Well,, Im clearly wrong somewhere, cuz that just sounds WAY too easy.
