Voltage Drop?

Voltage Drop?
hi all. i have a 2001 trailblazer 250. The problem is the headlight seems to be killing the battery. It's really dim, but when i rev up the motor it gets bright. I got a new battery and watched voltage being pulled from it at idle. When I revved the motor, voltage shot up to 12-13 volts. When the headlight is switched off, my voltages are better but not great. these readings are being taken from the battery terminals at idle. I'm feeling my way around this thing so I don't know what's what. I am open to suggestions Oh yeah, where is this water drain plug I've been reading about. thanks!!

Thanks for the info!! However I am still drawing a blank because with a new tested battery, headlight "on" My 01 has 6-7 volts at idle. Revved up, 12.
When the headlight is "off" the volts are like 8-9 maybe 10volts at idle. After a day of riding, the "new" battery will not fire the starter and measured voltages at that time are in the single digits

I'd say it's a voltage regulator problem or the stator is taking a crap. The bike should at least maintain 12 volts at idle regardless what year it is. Otherwise what would be the point of a 12 volt charging system? (Never heard older smaller polaris's ATV's do not charge at idle. That is the way they are.) (Say what??? and smoking what???)

yeah, shoulda been much more descriptive, but that is good to know then too.....I am new to atv's and dont have a clue about them.....but I am pretty mechanically inclined.....

like mentioned, i would check the connection of the recifier first to see if it is not corroded or even plugged in, broken wires or something as it is not charging. imo, your battery would not have no isues w/ the bike running w/ the light on at idle for extended periods of time. you should be easily seeing at idle 12.8 volts of charge into the battery and w/ the light on. your bike IS NOT CHARGING either due to what has been mentioned. you will kill the your new battery in time if you keep driving it this way. imo
