Swat 500 charging. Weak start
 

Hi all new to this forum,,,
Got a cfmoto swat 500 2010
Not sure if this had been asked yet,
But I've had trouble with a drained battery
I did all the tests. And all seems good , but I find
The head lights take the voltage way down
Is this a common problem,
I'm getting 14.5 volts but with lights it go's Dow to low 12s
I'm going to order led's
But wondering if there's any other reason for this
Thanks
