battery is not charging...

Hi everyone, my bike is not charging when I turn my lights on (previous owner
install a switch to turn lights on/off). I change my battery for a new one, put a new R/R and change its position, new stator replacement and the bike seems to work well, but when I turn the lights on, it drains the battery.
I don't now what else to do..... need some advise.
regards,

Try bypassing the on/off switch and see if that doesnt help.

Garage
sounds like a bad Reserve Lighting unit, or a bad ground in the light circuit...

Hmm.. I would expect smoke coming from somewhere if there is such a high fault load that it drains the battery even with a healthy charging system. What are your charging voltages when the headlight is off and on?

With lights off

12.5V up to 14V

With lights on

12.4 and starts dropping....

Batt. Chrg.

It sounds like you have connected the headlight out of the system; and when you turn the head light on; it does not load the electrical system and permit the voltage regulator to allow current to flow to the system.

It continues to shunt the alternator output to ground.

He did not mention added lights, just a switch, but that could explain it.

How do you make such a connection 'out of the system'?

What if you take the headlight bulb and a couple of wires and connect the bulb directly across the battery? This should show if the headlight is too much for the charging system or if there is some 'hidden' load behind your headlight switch.
