Bike just loses all electrical power - WHILE driving!

[bigbody300]

hey guys

well i took my bike to the shop (suzuki) a few weeks ago cause it died on me at the light...wouldnt even turn over after it died...then i charged the battery (its a new battery BTW) and its all ok, dealer told me charging system is fine....they thought loose battery connection was the prob.

well it died again on me!

charged it again starts now - POWER STATS:

battery (bike off) = 12.5 volts
bike on 2000 RPM = 13.9 volts
revving bike to 4000-5000 = 14.7 volts

SO WHAT IS THE DEAL!!!!

If its not a charging problem and you have replaced the battery-

this may be one of the Sh**tiest problems you can have..

It most likely that you have a short somewhere. Was it wet/raining when this happened? could be moisture related, something not sealed or closed up properly.
did you do any electical mods? check those first.

if not...
You need to take a voltmeter and test the bike in sections up and down.

b4 you do that- double check the connections on the fuse box.. occasionally it can be due to a loose fuse.

good luck

Do you ride in heavy traffic or stop and go?

I have a problem with past couple bikes that if it sits in stop and go for 30+ mins the bike will not start if I shut it down shortly after. Bikes don't charge when there sitting in traffic and will slowly drain the battery.

This is amplified if you have a power drain. Did you add higher wattage bulbs, new accessory, bike alarm, etc...?

The reg/rec will fail when warm/hot but work fine when cold. Let the bike warm up then try testing.

just because it's a new battery don't mean it's good. check to see if the battery will hold a charge on its own out of the bike.

do you still have the orginal regulator rectifier?

they'r known to burn plugs, the stator and rectifier.

but the charging stats seem fine....who tested it? and where are the specs from? Across the battery terminals?

Does it do it when its hot/cold? please describe the symptoms? When did it die? does it do this often?

btw a new battery doesn't mean it works well, has a load test been performed on it?

hi guys..its has happened 3 times now - randomly...

the only consistent thing is it happened when i stopped and then it shut off when i stopped or about to take off - this is also after the bike has been running for at least 30 min. of riding..

I should try testing voltage after a ride (as stated above)..now it starts no prob cause the battery is charged up..

i will also check the fuse box - which i assume is in the battery area ( i seen a fuse relay there) this is a 2001 GSXR 600

As for weather - it has not been rode in the rain...so no.

The relay with the 30A fuse is the main fuse....I think its on the left side of the tail...with the starter selenoid there too. I don't think the fuses have anything to do with it, cuz it will lose all power, and work fine when the bikes been on a tender.

The fuse block is located I think towards the left side of the front, beside the fork on the ram air duct..I think.

Its not a charging system issue if its comming up with those numbers...again those voltage numbers are from across the battery terminals?

You mean...you were riding for 30mins+ then come to a stop light, go to take off and it just dies?

Does it turn over? or there is nothing? no lights, no gauges, no dash lights nothing? or does it try to turn over but it doesn't have enough power?

WHen it dies out of the blue, and i look at the guages there are lights, VERY DIM, and will not crank..just click sound..

sounds like a battery problem
