bike wont start sometimes....

so i just got a new battery no more than 2 months ago from the dealer and the other day i went out to my bike, disarmed the scorpio and went to start it but it just kept "click click click" and wouldnt turn over, the lights worked,alarm worked but wouldnt turn on....got my girlfriends dad to hook up his chevy van with cables and hooked up the bike and it started and ran fine, and sat in the garage and started fine the next few days.....

then again it happened tonight...same exact thing but i noticed ont he way home when i hit the brakes the lights dim a little, but if im stopped and hit the throttle the lights brighten showing the battery is ok....also when i turn on the blinker the rear ones work but if i hit the brake they go REALLY dim i mean dim to the point of people cant see them on behind me unless i have my hands off the brakes....

can anyone help me out with the starting thing and the lights???? could it be a bad stator or did they give me a "lemon" battery

start by checking your charging output, and measure resistance on your regulator/rectifier as well. sounds like a charging problem due to a defective R/R to me.

Before you do that, I'd check the connections. A loose wire can act like that...

first, get a volt meter.
attach meter to battery terminals. it should be either be around 12 volts or less.
start engine and check at idle. it should be somewhere over 12 volts.
rev engine past 3k. it should be somewhere over 13 volts. if there is no change or is overcharging (14v+) then your charging system needs to be tested further.

if all tests okay, the starter may need to be tested.

I would dis-agree with BM..

Battery should register 12.8volts at all times unless the bike is running.

Anybody could probably varify with a quick check...

I am with Gas on this one. But also check for loose connections and if everything looks good then look into the charging system. Even new batteries are chit sometimes.

yea i will probaby test it and see what the meter says and then if it is the battery just take it to the dealer and have them give me a new one since this one is less than 2 months old....also i noticed the first time it wouldnt start, i would crank it and nothin happened but then the alarm beeped twice, it did this a few times i dont know what that means
