battery recharging
battery recharging
With a meter attached to the battery, when I increase the revs the voltage reading drops... is this right?? Also every other bike I've owned the headlight brightens when the bike is revved, this one stays the same brightness. Confused. P's I have replaced the reg rec to a Honda finned one.
Re: battery recharging
What meter readings are you getting ? Need to know the range. Check connections to the battery and starter solenoid.

Agree. This sounds like a dodgy connection somewhere. Headlight is a give away.Check connections to the battery and starter solenoid.

Give us a reading at the battery after the bike has been stood over night before starting. Another reading with the engine running and lights off, and another with the engine running with the lights on.
Also if your old un-finned rectifier failed, your battery and alternator could have suffered damage,

Re: battery recharging
Left bike overnight..v batt =13.0..engine running lights off..v batt =14.50...engine running lights on v batt =14.1.
Re: battery recharging
Those figure don't seem that far off to me, although I thought the voltage reading would have dropped a bit more when you turned the lights on with the engine running.Rlong wrote:Left bike overnight..v batt =13.0..engine running lights off..v batt =14.50...engine running lights on v batt =14.1.
How's the bike performing now including starting etc
Anyone else care to comment on those voltage readings

Re: battery recharging
A little low with the lights on as if something is drawing power. Otherwise those readings are not too bad for a non MOSFET. Have you got an alarm on the bike by any chance?
As I previously suggested check your connections particularly the R.R earth and the positive feed from the battery to the starter relay on the side of the subframe. Give them a good clean up and apply a bit of petroleum jelly to the connections. The ignition switch is another area for currant draw so it may be worth taking the front fairing off and checking your connector blocks up front. Give them a clean up too. Then check you voltages again. Do your voltages rise at all when you give the bike a rev?
Otherwise the battery may just be getting a bit old and tired. This time of year will take it's toll on batteries and the charging system.

Re: battery recharging
I have replaced the battery about a month ago. Think I will take your advise and look behind the front fairing as I have already checked the starter solenoid and reg rec earth, both are good. Many thanks for all the advise and suggestions.
