Default Overcharged battery

I overcharged my batt and when i went to start her i blew the main.
I do not want to keep going through 30's so i am wondering what i can do about this.
I cannot afford a new battery.

how did you overcharge it?

If it did get overcharged, about the only thing I can think of that would be damaged would be a cell or two. Im not sure if the cells can break and then become shorted internally, but thats a posibility.

It kind of sounds like you have another issue though. If your key is on, and everything is ok, and only goes bad once you try to start it. It may be a bad connection on your relay or starter itself. If you are shorting out in either of those areas, it will blow the main fuse. Try bump starting it and see if it will run. If it does, your issue is with the starter or relay. or even the starter switch.

The reason i had the battery out in the first place was because it went low trying to start it flooded. Backfires and all. I get too anxious sometimes. I have been meanin to get some sea foam through it.
So, i pulled the tank off and took a look at my air filter and pulled that off and did a surface inspection and a minor clean up of the carbs. There was some sort of foam chunk seated over the jets on one of the middle carbs. Even when i have flooded it before i was able to start it again soon enough but this time i just kept getting backfires.
I learned alot form a thread posted by a young lady who was having the same issue but i did not read it until after this all happened to my own bike.

I was too anxious and i put the charger on quick charge 40 and i turned my back for about 2 mins. and come walking up to a smoking batt and the internal breaker on the charger even went. So i was all "god i'm a dumbass" and figured that i shot my only bike battery. But i went to see if it still held and i threw it into the bike and turned the key and everything was kosher lights good i left it like that for a sec to see if anything would happen and it seemed alright. Since i had the tank off, my petcock was still on shut and i failed to recognize that until afterwords. I turned it over once, twice thrice and it blew.

The main is my first guess i haven't gone to check it yet but i did check the other fuses. It did turn over a couple times before it blew if that is of any consequence.

I was thinking that if the 12v was overcharged and it was putting out too many volts that logically the main electric protector on the bike would pop first thing.

I have had tons of electric issues with my f3. I feel like i just want to tear it all apart and put in a completely new system.

EDIT: now that i think about it before when i had bought some aftermarket blinks for the front
the lights got so hot that they melted the covers. Thats when i put in leds. After the leds were in though everything seemed fine. Idled for days without any apparent malfunction.
My components seem to be getting too much power. I have no idea why. I dont have a license
plate light hooked up and there are about three orphan connections in the back harness. Could that be why?

I would have to say your battery is toast, especially since the charger sensed a short and shut off. Take it out of the bike and have it load tested. Autozone will usually do this for free.

A battery has cells in it, within those cells are plates that are positive and negative. What can happen if the battery is overheated is those plates can melt or exploded. the plates are staggered positve and negative, so if one fails, its highly likely that you will have a negative and a posivite plate touch eachother and short out that cell. When you went to start the bike, it more than likley started on the remaining cells, but with the load on the battery, the shorted out cell took out the other cells and shorted out the entire battery.

If you need a replacement battery, I've had good luck with EBC batteries you see listed on ebay. They are half the cost of a Yusua and are decent. If you go with an off brand battery, just make sure to read the specs to make sure it meets or exceeds your specifications for your bike. The EBC batteries have the same specs and the Yusua for capacity, charging current, and cold cranking amps. Some batteries will not meet the same specs and should be avoided.

I pulled the air cleaner off and exposed the carbs. With the battery the way it is the bike actually turns over. (i will replace it as soon as i can) I am in hopes of finding an alternate problem because I am sure that it is not just the battery.

With all of the parts off (tank air filter/box/carb cover) with some fuel showing in the fuel filter I turned the bike over trying to flood it. I pushed back the sliders the butterfly valves are under to see them and they were still dry. Should i look towards my fuel relay for a problem?
It should have flooded and shown some fuel in the carbs shouldnt it?.

So it cranks over but just wont fire?

Im a little confused as to where you are in the process. I thought the problem was it wouldnt turn over and you didnt have any power at all?

what happens if you spray some starting fluid into the carbs? does it fire?

as far as your fuel delivery problem. that bike doesnt even need a fuel pump to run. It acts as booster on that bike as the lowest part of the gas tank is lower than the carbs, so the pump (which is only like 1.5 psi), only helps the gas get into the carbs. Once its in the carbs, the vaccum of the engine is what pulls the fuel from the carbs. Its basically a gravity fed system. If you hold the fuel filter and line up above the carbs, the fuel should fill the carbs up.

If you want to create as much gas as possilbe going into the cylinders, apply full throttle and crank it over. the added vaccum for the engine should pull gas from te carbs in a bigger more noticable way.

Yep, it turns over but doesnt fire. Got lights and gauges an everything.
The initial problem was that i had no power but that ended up being the positive on the batt was not making total contact. After checking a bunch of my wires with a light tester
i jiggled the positive and everything lit up.
I checked and cleaned my plugs and made sure the coils are fitted.
I also tried the throttle fully open method but it did not fire then either.
After the trial and errors of trying one thing then turning it over trying another then turning it over my batt is toast (again)

I am going to buy a new battery soon here then i will see what happens because the battery is still not holding full charge. I will go EBC ebay.

I will get some starting fluid and see what happens.
