NEVER put the red sealing cap back on the battery once you take it off. If you do, gases will become trapped and could explode.

How do I charge battery for suzuki s40

As on any vehicle, it's best but not absolutely necessary to remove the battery. If it has caps on the top (6ea), be sure they are all full to the marks on the case. Attach red-positive of the charger to the "+" on the battery, black-negative to the "-" (in a pinch to the frame or a bolt on the frame), your charger should show it's taking a charge. BE SAFE!!! Batteries emit combustible vapors while charging!!

I have a 1992 yamaha virago 1100 new battery will not keep charge once in motorcycle?

That happened to me last year on my virago 1100. Battery would fully charge, but not hold once in the bike. It was a brand new battery from GP Bikes. I took it back to the store and they checked the charge with their machine, which is better than mine. The battery was a lemon. They replaced it and the new one worked perfectly. But what a pain for a few weeks to figure out it was the battery and not the bike.

Motor run fine just died yesterday so I took seat off and the battery had blew off to caps were the acid is I replaced the battery rode it for about 15 miles then cut it off got a Gatorade and went to...

It's time to do a full check on your charging system; that's probably why it blew the caps off in the first place.
Odds are that new battery you put in is completely flat (lost charge).

I took out old battery on my 2004 honda vtx c,now i am having problem knowing witch side is positive and wich is negative on cables

Okay...the battery posts themselves should be identified with a + and -

As for the cables....often the positive cable is red, and has a rubber cap on the cable that covers the positve cable/battery post connection once bolted up. The negative cable does not have this cap. You should note that the positive cable runs from the battery to the main fuse of the bike, which usually is near the battery.

If feels like a pogo stick sometimes and also wants the front end to wash out too and on the front forks i have a oil leak

Your front fork seal are bad and need to be replaced.
When you loose fork oil, your loosing suspension dampening and only riding on the springs.(POGO)

Replace both front fork seals and dust caps, and put same amount of fork fluid in both forks.

I bought my seals and caps for $30 on ebay, and then took my forks off my bike and took them to a shop and they charged me $75 to do the job.

You can take them the whole bike and they will charge $100 - $150 including parts to do the job.

The power wire for the head light before the switch that moves it from high beam to low beam. It probably can be tapped in the head light bucket. You do not want to take power directly from the battery. You need to find a hot source after the voltage regulator or you will boil your capped battery dry or over charge your sealed battery.

How do you charge the battery?

Take your battery to your local auto parts dealer and they should charge for free..Though, assuming battery is low on acid, you will have to puchase battery acid and fill yourself prior to charge depending on whether you have a sealed battery or a refillable battery..The auto parts store should also let you know if its holding a charge..generally takes 24 hrs (trickle charge) depending on how they charge it. my car battery took 30 min. Refilled my hyosung battery with appropriate battery acid and turned out bad battery. I probably ruined by jumping it off while low on acid.

Battery charging

All lead-acid batteries contain highly corrosive sulfuric acid, generate explosive gases and have warning labels which should be observed closely. For best results, charge the battery as soon as you know it is discharged. To charge your battery, follow these steps and important safety tips: Before Charging: 1) Read the charger manufacturer's instructions. 2) Put on protective eyewear, rubber gloves, work clothes and remove all jewelry. 3) Place the battery in a well ventilated area. 4) Don't charge a frozen battery. Allow the battery to warm to about 60?F before charging. 5) If applicable, remove the vent caps and check the battery's water level and, if low, add distilled water to cover the tops of the plates. Do not overfill. 6) To determine if the battery needs to be charged, test it with a hydrometer to determine its specific gravity and/or with a voltmeter to determine its state of charge. 7) If applicable, reinstall vent caps before charging. 8) While the charger is unplugged, connect the leads to the proper battery terminals. Note: For side-post and studded batteries, we recommend that you use adapters to insure adequate contact. For additional information regarding adapters, contact Interstate Batteries. 9) Set the charger to the proper settings for your battery, e.g. 6 volts vs. 12 volts, low-maintenance vs. sealed, standard automotive vs. deep cycle. 10) Plug in and turn on the charger. 11) Don't wiggle the connections to check contact while the charger is turned on or plugged in. 12) Choose the lowest amperage setting initially. Once the charger is on and the battery is charging, you may want to choose a higher amp setting to reduce charge time. During Charging: 1) Keep the vent caps on. 2) Don't allow smoking, open flames or sparks near the battery. 3) Don't allow the battery to become hot to the touch. After Charging: 1) Immediately after the battery is fully charged, turn off and unplug the charger. Continuing to charge a fully charged battery will severely damage the internal plates and shorten battery life. 2) Disconnect the leads from the battery.
