Understanding The Charging System
I just installed my TPE stator and a mosfet regulator. With the bike idle and the battery is fully charged I see 14.- volts. Rev it and it increases a little bit. Well I went for a quick ride and on the way I noticed the bike stopped charging. Stopped at a shop to check and see what was going on. Voltmeter at the shop said the battery was around 13v and didn't increase much, never broke 14 volts. Played with the bullet connections from the stator and on the way home it seemed to charge again. It looks like one of the legs was loose or got disconnected. With two of the legs still connected why didn't it charge?
Can someone also explain if the bike should be charging no matter what rpm range? I have heard that the bike doesn't charge much at idle. But on that ride my meter, got the one that is just an led light, went from green to amber a lot. Didn't seem to stay green for that long before going amber. Sometimes I would see it flash red but I think that is when the connection got loose.
The warning indications are as follows:
Green, light charging fine, The window is about 13.2 to 14.8 volts.
Green and red alternating is over voltage (over 15 volts, not good)
Amber, (bike running) hook up a voltmeter on your bike and see what's happening with it running.
Red or red flashing means your bike is probably not running and you have your lights on, or if your bike is running there is trouble in paradise and you need to take action not to get stranded.
