Question about kawasaki VN 800 Vulcan Classic Motorcycles

1 Answer

I installed a shark audio amplifier on my bike. battery died.I tried a small trickle charger to recharge batt but somehow killed the charger.I disconnected shark amplifier and led lights, then bought a new battery.New battery ran low and had to push start the bike to get home.I used an external charger to recharge battery. bike starts fine but noticed that voltmeter across battery terminals did not increase voltage on start up. checked fuses I could find (30 amp under right cover and several 10 amp fuses under left cover. I don't have schematics yet. Any ideas?

It sounds like your charging system is out. use your volt meter check the battery charge before you start the bike, it should read about 12 volt, start your bike now, check you meter you should be running about 13.5 volts. rev your bike watch your meter it should spike around 14.5 if your meter jumps up over 15 your reg/rec is not working right, if it drops when you rev the bike you stator is not working. Its always best to replace them as a pair as they work as a pair and bad old part can kill a nice new pricey part if you follow what im saying. the stator is the coil winding that makes a/c power after its made it goes to regulator/ rectifier it's job is take that a/c power and make it d/c (you can only make a/c power and store d/c power) it also regulates the volts around 13.5. see what you got and let me know
hope this helps

How could I hookup my led light bar to my Baja 125 dirt runner? There is no battery. It's a kickstart. I need alight on it asap.


Buy one with a battery or buy a battery and mount with switch on bike somehow. Small 12 volt rechargeable gel-cells are available at Home Depot for $30. You would have to recharge it from time to time.

I'm pretty sure your bike has a magneto ignition system and does not need 12 volt DC power to operate it.

It has either a generator or alternator style system. So ya your killing the battery and need to stop that till you fix the generator charging system. Check the fuses and wires for any breaks. May need a new stator or charging controller if the fuses are not the problem. May be even a bad ground wire.

How to recharge my dead batt.


depends on how long they been in that state, more than a few months might have ruined them. the best way is to remove them from chair, charge on a trickle for a few hours each, you have two 12 volt batteries, reinstall them and try your factory charger if no results call a repair center

sounds like the battery doesn't have enough power.
Battery may be bad, or your charging system is bad.
If the bike was sitting for a while not being ridden (longer than 3 weeks) then the battery is probably dead.
go to a local powersports shop and ask them about a "trickle charger" this is what you plug the bike into when you park the bike for a long time like the winter. You can dfind a cheap charger for about $20. It has to be a trickle charger not a regular battery charger otherwise it could overcharge and the battery could explode or even catch fire. This will keep your battery from dieing everytime you park the bike for an extended period of time.

How to start motorcycle? It's been sitting idle for the winter, and I believe the battery is dead, can I hook it up to a charger? And where is it located on the bike?


Battery location depends on the bike but usually they are under the seat area.

They battery can be charged, but select a decent charger for bike batteries. If the battery is dry (out of water/acid) the battery will most likely be NS. You can pry off the plates on the battery and top up with distilled water and try charging but I would just get a new one and charger at the same time. You can get trickle chargers, that you leave connected to the batt when not riding the bike and it flicks on then off to keep the battery topped up. I had my car on one for a year and it was fine.

Kiil my battery


with the lights on for well over a week. (in my locked garage incase your wondering why I still have a bike) Needless to say the battery is dead. It's been on a trickle charger since Sunday afternoon (now Tuesday afternoon) and it still indicates charging. We did try it in the bike anyways and no go. Do you think I killed it? The dealership told me it might take a good 2-3 days to charge it back up if I didn't kill it. The battery is 3 months old.... should I just go out a buy a new battery at this point? Ahhh....lessons learned the hard way. Slap a trickle charger with a float on it and see what happens. No way to find out how bad it is until you try to fix it. And draining then charging a battery is one of the worst things you can do to it. Personally, I couldn't stand not riding for 3 days, so I'd buy a new battery anyways. But that's just me.,,,
