I’ve never heard of any vehicle with lights that are fed regulated 12V! Normally[1] there’s a regulator to make sure the battery doesn’t charge to more than 14.4V, and the rest of the bike is fed from the battery, with most things ignition switched. Exceptions would be hazards, immobiliser etc. There may well be regulators for electronic bits’n’bobs (probably internally to each one), but not for any of the high current devices like lights, horn, heated grips etc.
[1] On some older bikes the battery itself was the regulator, as the magneto pick-off couldn’t overcharge it if it tried. However disconnect the battery and the lights would blow…
No the Oxford grips are nothing like the manufacturers grips, the ones I sell a whole heap load of on Ebay on the other hand are very much the same type.
I brought a pair from Hein Gericke, and fitted to my CBR600 but all it get is the blue light flashing when i switch them on. According to the manual that mean there is not enough voltage.
Has anybody had this problem, or know what this might be.
I have them wired straight to my battery at the moment, but will fit a relay when they are working.
My battery is under 1 year old so I know there is noe problems with that.
Is that with the bike running? If they won’t work at 12V, but will at 13.6V, then they should work while the battery is being charged, yet prevent drain when it isn’t. A bit like using that relay you were thinking of.
Most Honda’s don’t charge unless the bike is running at greater than 2500 revs, so just having it started on tickover won’t be enough get the revs up and then try it.
As for “relying” on the cut off to prevent battery drain, sorry I would’t personally, Oxford make reasonable products but the opportunity for something to go wrong is still there and I would always use a relay or switched source
All Sorted now, they work fine with the Lights on, but need at least 2000revs to get them going. If they drop below this or you switch off the engine they go off after about 15-20 secs.
Thank god I’m not the only one with this humour, I was getting lonely
