billy sugger Posted July 16, 2022 Share Posted July 16, 2022 Below is a pic of my Cbf600sa8 wiring diagram. I am looking to fit an on/off switch in the dipped beam circuit to disable the light being on from the moment the key is turned to start the bike, (it momentarily goes off as the starter button is pressed. My commute to work is only 3.9miles and I believe the light being on is detrimental to charging the battery. I have a voltage indicator fitted, and this is showing a reading of 11.6 volt. The bike starts first time and runs fine, but I think the trip is too short to replace what's used and I don't want to bugger up the battery as its less than six months old. So to all you electrical wizards out there, where should I break into the wiring? Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted July 16, 2022 Share Posted July 16, 2022 If you open the headlight housing and put a switch in line with the live cable that would do the trick. But to be honest it won't really make much difference. I'd rather keep the headlight for safety and if necessary install a charger lead to trickle charge the battery each night. 1 Quote Link to comment Share on other sites More sharing options...
Gerontious Posted July 16, 2022 Share Posted July 16, 2022 I realise we’re all different, but personally, I just wouldn’t use a mid size bike for such a short commute. Sub 4 miles just isn’t far enough for the engine to warm up properly. And that would be a greater concern to me than the battery. But regardless of that I feel you have created a problem that doesn’t really exis, the drain from a dip beam is negligible and not worth worrying about.

onesea Posted July 16, 2022 Share Posted July 16, 2022 I feel your pain my commute to work is 1.5miles, it eats car batteries if I use the car particularly in the winter. My solution on the bike is to charge the battery at work every couple of weeks. Although I have a bike alarm that further drains the battery. I don’t think it’s the headlight that drains the battery, they’re just not getting enough run time to get a decent charge back in the battery. Particularly after the amp-age used to start the engine. It is the downside of such a short commute, it’s hard on motor vehicles. I know I am in theoretical walking/ cycling distance. However I don’t fancy my chances at all hours on unlit roads (that are a bit of a rat run) with no pavements. Quote Link to comment Share on other sites More sharing options...
Stu Posted July 16, 2022 Share Posted July 16, 2022 What about fitting an LED bulb instead? You can get some really good ones that don't scatter the light LED will obviously be less of a drain on the battery Quote Link to comment Share on other sites More sharing options...
billy sugger Posted July 16, 2022 Author Share Posted July 16, 2022 When I had the rear tyre blow out on the way home from Narborough it was on an unlit country road at night so the engine was left running whilst waiting for recovery. Only the headlight was on yet it drained the battery on tickover. The recovery guy turned off the ignition, not sure why, then realised he needed the engine running but it would not start due to a flat battery. My headlight is a HID unit, so probably consumes a lot of juice. I already have a smart battery maintainer wired to the battery so it's just a case of plug it in and forget it. @Gerontious the 600 was never meant to be my commuter bike, but the 500 engine bust a conrod and I'm in the middle of repairing it Quote Link to comment Share on other sites More sharing options...

Some of the cheaper ones have the led in the wrong place so the beam of light is altered I fitted some to the FJR and they was brilliant Quote Link to comment Share on other sites More sharing options...

On the face of it it actually looked really bright when setting it up against my garage wall, but in reality, (to me anyway), on the dark roads home I could see even less of the tarmac than under halogen so I ditched it and went for HID. it probably didn't help having separate lenses for high and dipped beam, so the reflector shape could have been wrong, but the HID unit is designed for my light set-up so that's what I use now, and I have to admit it's brilliant at night Quote Link to comment Share on other sites More sharing options...

Tiggie Posted July 18, 2022 Share Posted July 18, 2022 I get the theory behind it happening but haven't had an issue myself for years over different cars when bump starting. Worth bearing in mind though My car is a Toyota Aygo and ridiculously easy to bump. Barely need to get moving and it'll fire right up when you let clutch out slowly in 2nd.

husoi Posted July 19, 2022 Share Posted July 19, 2022 Keep in mind that it is mandatory for motorbikes to have the dipped headlights on at all times while ridding. I would advise a trickle charger at home over night instead. 1 Quote Link to comment Share on other sites More sharing options...

Ian Frog Posted July 19, 2022 Share Posted July 19, 2022 I thought it was like Saab`s and Volvo`s someone started doing it and common sense meant other manufacturers followed. Does this mean my old GS750 shouldn`t have been granted it last few MOT`s as I rode it to the test centre without the lights on and the tester had to turn them on ?

Tiggie Posted July 19, 2022 Share Posted July 19, 2022 It became mandatory after a certain year. Can't be arsed googling when, it's too hot My 2001 Suzuki didn't have them Quote Link to comment Share on other sites More sharing options...
Ian Frog Posted July 19, 2022 Share Posted July 19, 2022 Wow I must have slept through that one lol. Must pay more attention. My 2004 ZRX is the earliest thing I remember where the light on/off switch was missing. Cheers Ian 1 Quote Link to comment Share on other sites More sharing options...

oldgrump Posted July 19, 2022 Share Posted July 19, 2022 My VFR800's have light switches, 98/2000 plates, only bike I have is the 2004 SV1000, that came with lights permanently on!! But my mate who brought the Sv from new put a switch in to turn it off, because he was worried battery would go flat! on start up. I never use the switch on SV, but sometimes on the VFR's I turn the lights off. Quote Link to comment Share on other sites More sharing options...
husoi Posted July 20, 2022 Share Posted July 20, 2022 1st January 2016 The introduction of AOH (always on headlights) which applies to all new motorcycles imported into the UK from 1st January 2016 is a source of concern to MAG. MAG is concerned that this has been pushed through by EU bureaucrats with no evidence to prove that it will deliver enough benefit to justify the measure.

I think a bigger threat to most motorcyclists now is the number of cars with daylight running lights. Meaning there lights can hide cyclists and motorcycles. The battle to the brightest lights is not necessarily a good thing. 1 Quote Link to comment Share on other sites More sharing options...
