Bike problems - continued!

[matt-sherr]

So, following my older post i started to replace and test suspected parts of the bike that may be causing some problems. Following the advice off others and searching through forums i noticed that my old alternator wasn't putting out as many volts as perhaps it should so i decided to replace certain parts. I have replaced to date, the stator, the regulator rectifier and the battery and was hoping this solved the problem. I left the bike on a trickle charge over night hoping that this would be what the battery needs.

I returned to the bike this afternoon, came to switch my bike on and it did start, so i decided to test certain points with my multimeter.

Below are the values that my bike were giving out so i suspect the problem hasn't been solved, but any input from anyone will be appreciated.

Battery whilst idling - 12.47-12.49 volts (slowly increases)

battery whilst revving - 12.34 (and continues to drop when revving)

battery when bike switched off - sitting comfortably and stable for a good while at 12.58 volts.

My main concern is the fact the voltage drops as i rev the bike, which is what i suspected the problem was previously as my bike would work fine then when i tried to start it when leaving work later the same evening the battery would be dead. Any idea what could be draining my battery whilst revving (bearing in mind i have fitted a new stator and reg/ rec?)

Checked/replaced all fuses? Something is creating a draw on the battery, not speaking from a bike knowledge here, just an electrical knowledge.

Could be something as simple as a loose connection, go over everything carefully, check grounds, check all cabling, change all fuses. That'd be my first and entirely uninformed about bikes advice

Good luck.

Looks too low to me.......should be around 13.5v with the engine running. New Stator or 2nd hand? I'd be checking the condition of all connectors in the charging circuit......also the condition of the ground wire from the battery to the engine.....Make sure that the connection at both ends is clean.....

With the engine running the voltage should be over 13 volts.

so, after testing my new stator i bought and put in using my multimeter - based on several youtube videos i can confirm the stator is working as it should be so now i have the unfortunate issue of having to check every connector and earth point?

check what voltage is coming out of the reg/rec first

if you are getting somewhere around 13V+ then you have an issue with the wiring from there to the battery

If you are getting nothing then the reg/rec is gone
