So I have 2 55w auto fog lights and have hooked 1 up so far. Helps out alot at night. My question is will this kill my batt completely/have any other consequences? Its wired thru a switch which is batt to switch, ground to switch with a power wire coming off the switch to the light and the ground from the light is on the negative batt terminal. I do not use it during the day, but would like to hook up the second for night riding... will this cause any ill effects?

you need to know the rated wattage output of the bike (should be in the service manual)
then the wattage of everything running (lights mostly.. everything else we can guess reasonably accurately, but if its in the manual post it)
then the wattage of the lights. and do the math to see how far over you are.
although i would use a meter and test that way.. at the very least, use a voltmeter and see what the power drops to...
ex:
say, if you have the bike running at cruising RPM and it makes 14.0v... and you turn the lights on and its still 14.0v, then you're perfectly ok.
if you have the bike running at cruising RPM and it makes 14.0v... and you turn the lights on and its makes 13.0 - 13.5v, then you're getting close to pushing it, and id check the stator output wires carefully. for awhile, especially their connections but you should be ok. the battery is still charging when you're moving.
if it drops to battery voltage (12.5ish) or lower... then its far too much.
thats just another way of doing it... probably the easiest.

Either get a new stator ( trail-tech or Baja designs ) or have baja designs rewind your stator.....i have a 07 510, had my stator rewound and did a hid conversion...100% better :thumbup:
