Bike turns over on first try but not second.... - Page 2

Take off the seat.
Take off the right side panel.
The battery post will be on this side.
Put + to + and - to - from an automobile.
+ positive =hot.
- neg= ground.
Do not start the automobile.
Try to start the GZ and report back.

PS download the pdf manual and read it and look at the pictures a few times...good reference.

I have the manual I know how to connect them like that I thought there was some other way haha.
I charged my battery to 100% drove around 14-15 miles turned it off and checked the battery and it was at 12%

JWR · 03-13-2011, 10:03 PM

You did not answer the question of how LONG DID YOU CHARGE THE BATTERY.
1 hour 2 hours ????

Have you ever tried to boost it off???

Kayrub · 03-13-2011, 10:08 PM

Here's whole story of today. I started off with the gel battery charged at 100% it had been on the charger for a good hour. I left my acid batter on the charge while I went out to ride, It was on the charger for around 2-3 hours. I went riding for about 20-30 minutes and parked at gamestop hung out for a bit with my friends for about 1-2hrs I went to start it and it wouldn't crank over. So in order to get home I push started it and while driving down the road about 3-4 miles my bike died, tried to push start wouldn't work lights were dim. Brought the fully charged acid battery put it on started right up, rode home about 13-15 miles turned it off immediately and put it on our battery reader and it read 12%

Acid batteries has a series of actions you must follow.

One of those steps is a 6-8 hour charge.

HAVE you ever tried to boost the bike when it will not start????????????????????????????????????????????? ???

Your battery is dead. Plain and simple. What measured 100%?, reading off the charger? More importantly, what was the voltage?, not the "charge" reading.
Can you please tell me what you charged it with? You need to have it on a 2 amp charger for 6-8 hours to fully charge it.

You have to charge the battery, then let it sit for at least a half hour to dissipate the "surface charge", then measure the voltage. It should be 12.8 fully charged. The reading of "100%" off the charger means very little. But if it said 12 % later, that battery cannot hold a charge, it is shot, dead, like I said. Charge it again. to 100% if you want, don"t touch it, measure it again 6 hrs. later and see what it says.
That's exactly what happens to a new AGM battery not fully charged before you first use it.

Also if you measure the resting battery voltage as a baseline and then get the bike started, then rev it up to 3000 rpm or more, the voltage at the battery should read 13.5-14V and that tells you the charging system is OK.

BTW, make sure all your battery connections and your bike ground are clean and tight.

Don't keep replacing parts until you reason out what is wrong, you are facing a bottomless pit and going nowhere. Please answer all my questions and those of others if you really want some help to figure this out.
I'm sure your battery is the problem. It probably was never fully charged in the first place.

I replaced the starter because a mechanic had told my father that's what the problem seemed like since we had replaced the battery, then we thought maybe for some reason we had fouled the spark plug and just put a new one in for good measure, It's a 2000 gz250 has around 1300 miles on it. It has been sitting in my Uncle's garage since oct-nov I believe.

Kayrub · 03-13-2011, 10:20 PM

A batter tender it read 100% charge and it did have a 12.8 reading on the voltage.
I've never jumped it from a car before.

Kay,

The most important thing mentioned above is: you can't charge a battery in one hour. The batteries charge best at the lower amp setting (on the charger) and typically should be charged overnight (12 hours at least.)

It's theoretically possible that your problem is something other than a dead battery, but, until you've eliminated that (which, based on what you've told us, you haven't) it's the most likely cause.

Also, many, many people have posted on here with trouble starting and, if it is not a choke/carb problem it is almost always the battery. Weak as the charging system is, it appears to be pretty reliable.

mrlmd1 · 03-13-2011, 10:30 PM

The mechanic replaced your starter? Did he test yours first to see if the original one would work connected directly to a good battery? Sounds to me like you should change your mechanic, not your starter, or spark plug. Spark plugs have nothing to do with the starter engaging or turning over, but a clean new plug never hurts (unless it's not gapped properly).

You never answered me - you are not leaving your rear parking lights on when you walk away from the bike, are you?

As a totally different problem, having NOTHING to do with the one you are presenting here, it would be a good idea to put some Seafoam or Berryman's B12 Chemtool in the gas tank, 1 oz/gal of fuel, to clean up the carb from fuel sitting in it for the past 5-6 months.
