storm charge rate

Post by solorider »

my storm decided to nreak down a couple of days ago,it cut out (i work colleuge was riding it and probably stalled it),i had the bike jump started and rode home with no problems,did a charge rate check and getting 14.5 volts at idle,volts drop slightly as you rev the engine (not what i would expect,i parked the bike up and did a new check,13v at battery,try and start bike and you get 7v drop (6volts) and bike wont crank.i have charged the battery for 24 hours and bike starts first time no problem,i realise the battery does need changing so do anyone use either a cheap battery or go for the more expensive option? also do my charge rates seem allright? i would expect a slightly lower figure at idle and going up as you rev the engine,the charge rate with the headlights goes doen slightly t0 14.2 volts at idle and 13.9 volts while revving (80/100 watt bulb)

Voltages sound ok to me, much the same as every bike I have ever owned in fact.

Put your meter to the AC volts range and see what you get then, any significant ac volts say over about 1v will destroy the battery in qucik time.

If the volts were around 30v odd then yes the regulator has gone and if ac is present then the rectifier part has gone, expect some ac volts reading though as no rectifier will get rid totally of ripple.

The most likely cause of the flat battery is the high wattage headlight bulb especially is you ride with it on all the time.

If you have one of the original unfinned r/r's though I would remove it clean the frame and mounting bolts up and put a small smear of silver laden cpu heat transfer paste on before bolting it up again minimum as they do get damn hot.

I have done this and have also put some pc ram heatsinks on it so we will see how it goes. Not too sure how this will work as the potting is lower than surrounding case which means only a very small area for the 'sinks to stick to, may have to remount them somewhere else or just put some more on.

This is an old problem; going all the way back to the Crimean war, where the charge of the Light Brigade was 7/6d per hour.

This equates to almost £3.00 in today's money, plus Gordon's taxes, so just over £27000539577251214644658820644.97

Hope this helps :D
It's not falling off, it's an upgrade opportunity.
