motorcycle battery not charging while running

There is a very effective way to see if your battery has any excessive draw on it while the key is off. Car repair, Car Service. This site is owned and operated by Cannon Entities LLC. Typically a standard circuit wire has at least .01 Ω of resistance. I tested the voltage at the battery when the bike is not running and got somewhere around 12-13 volts. One of the most aggravating things a motorcycle can do to us riders is leave us stranded because the battery won’t work. • Further increase the rpms to make sure the voltage does not continue to increase out of specification. The car or truck, if it is not running, is only going to send 12V. Rchab Member. A typical motorcycle battery should last up to 48 months, or 4 years. This battery is getting weak. Checked ac output from stator. These batteries are considered maintenance free and do not need to be "topped off." I wound up push starting the bike and i got it running. A visual indicator lights. Remove the battery. A Short in the electrical system. Let me explain…. Battery charging problems sometimes arise. Your battery may even be holding a charge, but it's the cold cranking amps that may determine if your battery needs replacement. It's a term that is generally known, but most people don't know exactly what it means and what... My name is Kyle Cannon and I love everything about motorcycles. A good way to tell if this is happening is to check the battery cables for excessive heat. How to charge a battery. Keep in mind that this process is happening faster then you can see. Battery takes a charge from battery charger and holds the charge. Unless you have additional electrical ad-ons, that’s basically all the battery does. It's just a little smaller and doesn't have to produce the same electrical load as a car battery. Knowing how to take care of and properly charge your motorcycle battery helps ensure your battery enjoys a long life. No need to go running to a dealership to spend money. There are a few symptoms you can look for to know if you’re truly dealing with the issue of the battery draining while you ride your motorcycle. A short in the electrical system can definitely drain your battery in a … A dead motorcycle battery is a drag, but it won’t ruin your day. Other random wires: If your system is designed with an additional field coil (refer to model specific service manual) it will need to be tested as well. Note the reading. Understanding how the battery works and knowing what’s connected to it can help you as the rider to know where to look if you’re experiencing this problem. If the voltage shown on the multimeter is less than 11 volts, your battery should be charged (13 to 13.6 volts is ideal). Too much charge can cause overheating, meltdowns, explosions, and fires. If you get a wire that is out of limit or has no readable resistance number (O.L). There are several reasons why a motorcycle battery drains while riding including a bad battery terminal connection, corroded battery terminals, a bad stator, a bad rectifier/regulator, too many electrical add-ons, too old of a battery, and if you have a newer motorcycle, an automatic shut-off will happen if the battery cable vibrates loose. But it’s not uncommon for them to quit before that. Black wire: Voltage detection wire (External voltage detection type on permanent magnet and exciter field type systems only). Let’s get to work! First, check all the connections to the battery and make sure everything is snug. Video-Is your Harley-Davidson or other brand motorcycle seem to be cranking over slowly when starting? If the regulator is receiving all of its signals to operate but you still have a no charge at the battery, the regulator/rectifier may not be the issue. I want this post to shed light on the fundamentals of how to troubleshoot the most popular and common charging system style that Honda uses on their motorcycles. At idle, your bike will not produce enough voltage to recharge a battery, so even running the bike for a long time will not charge it reliably. Motorcycle battery was not charging while riding, bike died out? This needs to be 12.5volts or above for accurate testing results Bike Battery Charging Problems - Troubleshooting & Fixing This procedure can help you find out why your bike battery does not charge correctly, and help you to fix that. 4. *Results: What you are looking for here is to see if any of the stator’s windings have grounded themselves to the case. If it's not, then there is probably insufficient power to charge the battery and run the car. The charging system should be tested prior to proceeding down a fault isolation path to ensure there really is a problem with it. Motorcycle battery charging questions..... Do I have to charge a motorcycle battery? So if he were to just sit at a light at idle technically until his battery was low it could die and not start. The stator needs to  be replaced. Battery – Stores regulated DC current. Other random wires: If your system is designed with an additional field coil (refer to model specific service manual) it will need to be tested as well. • Now rev the motorcycle’s rpms up to around 3,000rpms and hold. In order to test all of them, you need a small multimeter, you can get on for ten bucks. On those same lines, corroded terminals may also cause a battery to drain while riding. Ac volts goes from about 8-9 volts at low idle to 40- 50 volts at 2000- 3000 rpm. To accomplish this switch, the rectifier is made up of diodes. • Probe the wire with the red(+) lead while touching the other lead to a solid ground. You may get 0.2volts (+ or -) during any one of these checks and that is OK! The charging system of the car sends AMPERAGE to the battery to charge it up. When a motorcycle has a bad terminal connection, that means the battery cable either has a poor connection or isn’t connected at all. Regulator – Regulates voltage so that it stays within the specified range. 2. If the battery voltage increased to at least 14.2 Volts but not over 14.8 Volts, the charging circuit is working properly. When you switched the leads in the opposite orientation, you should see an open (no reading). Electrical & Ignition. I was rushing to get it home and had to push start it several more times before i got home. Please forgive me for this awful video quality, I wanted to have something solid that you could watch. Battery not charging while running. If your battery is charging perfectly but your motorcycle still seems to keep killing the battery. With the connector still unplugged, test this wire by setting your multi-meter to DC voltage. Your motorcycle’s charging system check is complete! This could be one of several things. • Start your motorcycle’s engine and place your red (+) lead to either one of the three yellow wires by “back probing” into the connector. Do this with all three of the yellow wires. These readings should be closely in range of each other. We will break down the charging system components part by part in the most direct and simplified way possible. In which case the stator has begun to break down or is bad. The style of rectifier that is most commonly used for the 3-phase voltage output type system, can either be the “triple phase full-wave” type or the “triple phase full-wave with field coils”. With the battery located, you have two choices: i) attach the charger with the battery in the bike, or ii) remove the battery and charge it elsewhere. • Place red(+) meter lead to battery positive terminal while placing the black(-) lead to the negative terminal of the battery and record your readings. Either way, testing is pretty much the same. Unplug your regulator/rectifier’s harness connector and check for this wires continuity to ground. ↑ Most common stator and flywheel combination ↑. Step 10: You're All Done! Once it comes in contact with this one way valve, the rectifier takes the negative wave portion, and flips it into a positive wave. if not, your charging system has an issue Since the rectifier is made up of multiple “one way valves”, we need ensure that they are doing their individual jobs for the AC to DC switch. The first and most obvious symptom is your motorcycle losing power and acting more sluggish as time goes on. Home Posts filed under Search results for Motorcycle If the voltage starts O.K. A battery draining while riding could also be simply due to a bad battery. While both are typically 12 volt batteries, a motorcycle battery has less Amperage and requires less amp charge rate. What... Can You Ride A Motorcycle With A Blown Head Gasket? Now switch your meter leads and retest.
