Charging

[Guest]

Hi guys I had problems with my bike not charging the battery properly. Cleaned all the earths etc and now have 13.5 on meter when testing it. Is this enough or should it be higher. Thanks

Sounds about right from what I saw. Have you gone through the stator papers though?

Its better than a continuous drain, but is that 13.5V measurement with the RPMs up or at idle? Need to give her some throttle to properly test the stator/reg-rect for proper charging voltage back at the battery. If only 13.5 when reved that might be too low?

Hi guys it was reading 13.5 with the revs high, not sure if they were as high as 5K though as I don't have a rev counter fitted to bike. Will go through stator paper test tommorow. Thanks again

if so then probably bad connections between the positive side of battery and the R/R.

If it went up to 14V and then started backing down at even higher RPM that is "fold back" associated with poor connections. Voltage at teh batter ydrops as youi try to push curretnt to it from a fixed voltage output at the R/R

Is the bike capable of being ridden? Get it up to 70 mph (110 kph) and notice the sound of the engine. THAT is 5,000 rpm.

Hi it stayed static at about 13.5V didn't drop down at all when throttle held steady.

fold back means
"drops with RPM"

NOT

"drops with time"

Next thing to try is to run a ground wire directly from the battery negative terminal to the R/R and retest
