Replaced battery now there is no power to the bike

Amperage is what turns your starter, not voltage. U may have 12 volt indication but the battery may not really have a charge sufficient to start bike. Have battery checked at auto zone, etc - they have the gear with which to it and give you proper guidance on matter.

charging system needs to be checked. runs good till the battery looses power then the bike starts loosing spark and or fuel injection starts to fail

Yes, yes, and no, and I don't know. You could have blown a fuse, but it seems it would be showing other symptoms if you did. THe age of the battery is a good indication of condition, over one year old, suspect, over 2 years old, definitely could be in need of replacement. Check the water in the battery and fill it to the level with bottled water, or rain water, no minerals, then get one of those floaty ball testers and check the electrolyte fluid weight, One dead cell, the battery is shot. Could have been not enough time to charge it back it up. A battery charger needs to run all night. So, check it out, hope this helps.

Most likely it is your battery. If it started when you jump started it then the battery was too weak, and it won't hold a charge, so when you park it overnigt it is not strong enough to start the bike. You may have loose or corroded cables and that can lead to a weak battery because it wasn't getting charged like it should. Unfortunatly when bike batteries get that weak they usually need replaced. Unlike a car battery they can't take the punishment of improper charging.

how old is your battery? if it is 2 to 3 years old it may need to be
replaced . charge it up and see if it keeps charge, crank your bike
run it for a short time 4 or 5 min. shut it , and try to start it. if it
drags when cranking go buy new battery.

It takes time to charge the battery. Maybe you have an old battery, replace it.

Did you get your problem fixed. I have a similar one - new battery - started fine several times and now won't start without hooking the battery to either a jump or putting on a charger. If you can help - I am w8bnl at yahoo dot com. Tom - thanks

Yes the brakes will work if the bike does so you can take a breath of relief because there is no brake booster it is just hydraulic pressure from the hand and foot switch. What i think may be happening with this bike is a faulty regulator rectifier. This will cause the battery to die with the key off AND it will also cause the battery not to charge correctly when the bike is running. It may hold a charge but will not charge further. What this unit will do is keep the voltage consistent from the alternator charge.

hi no way all the guy wants is money any good guy has the right test gear and would test all the charging /starter compnants before replacing the whole caboose buy youself a small cheap volt meter £5/£8 check the battery voltage start motor needle should go up to around 14 put lights on needle should not drop if this is ok then rr and stator is ok stop motor leave lights on if voltage drops rapidly battery is us hope this helps merlinv12

came out of the coffee shop went to start the bike and the battery didn't have enough power to turn over the motor....I pushed started it but it didn't want to stay running once I put it in gear. Last night charged the battery and today put it in the bike and it started right up....rode it for about 45 minutes waited for about half an hour before starting it up again and it started , no problem. I am thinking that maybe it is the voltage regulator or maybe the alternator....can anyone help me out with this? ,If you have a multimeter, you need to test the electrical output of the charging system. (Check the voltage of the battery when the bike is revving at about 2000 rpm) If you don't have a multimeter, the best thing to do probably is to take the bike to an Autozone or similar car place where they will test the battery and charging system for free,,,
