This usually results in a sudden shut-off from the motorcycle. While you are ridding your motorcycle, the charging system provides electrical power to run electrical components and accessories. It's just a little smaller and doesn't have to produce the same electrical load as a car battery. Red or red/white wire: Battery voltage (may have two wires). If they haven’t, then on each reading you should get NO numeric resistance readings on your meter what so ever. Be in the know on whether you actually need a new motorcycle battery or not. Your charging system is putting out the necessary voltage to the battery during a running condition (past idle). Most of the electrical components will operate satisfactorily with a voltage between 12 and 15.8 volts DC. A dead motorcycle battery is a drag, but it won’t ruin your day. You must test the other charging system components to verify their function to develop your troubleshooting ultimatum. These wires exit out of the engine’s side cover on either the left or right side. Testing The Charging System. But because your car battery is more powerful that your motorcycle battery, it's important to be careful when charging latter with the former. You also have the option of getting a jump start either from another motorcycle or from a car. While the engine is running, connect the voltmeter as before. Take a look at the expiration date of your battery; if it’s close, it may be time to get a new one. Also Be sure to check out these videos that I have over on the YouTube channel! A Short in the electrical system. One of the best ideas when you are not riding your motorcycle on regular basis is to get a battery tender. Unless you have additional electrical ad-ons, that’s basically all the battery does. Jump-Starting the Battery Get jumper cables. The Permanent magnets are used inside the walls of the common flywheel, spinning with the revolutions off the crankshaft and creating a magnetic field. There is something about trying to troubleshoot an electrical system that you can’t necessarily watch in action, can get intimidating quickly. So if he were to just sit at a light at idle technically until his battery was low it could die and not start. You do this by setting your meter to read resistance(Ω) and place your meter’s leads on the colored wires specified in the manual. To accomplish this switch, the rectifier is made up of diodes. Checked for shorts or opens … With the connector still unplugged, test this wire by setting your multi-meter to DC voltage. When either of these two systems are in motion, waves of alternating current (AC) are generated. Battery takes a charge from battery charger and holds the charge. The stator needs to be replaced. Blog about Car and Automotive. a good new battery properly maintained will last at least a few years. This outcome needs to be the same on every diode you test. Or you may find it's not the battery at all and a charging system problem instead. This NEEDS to be correctly charged and tested before you start and troubleshooting. 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. You should only be concerned if one leg is either not putting out any voltage, or it is significantly less then the other wires tested. Most car drivers tend to always carry a pair of jumper … Joined: Oct 29, 2020 Location: Lincoln, Nebraska Local Time: 3:13 AM. Newer batteries can last longer with an average of 3 – 5 months until dying whereas older batteries will not last as long giving it an average of 1 – 3 months until the battery dies while the motorcycle is sitting. 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. This doesn’t necessarily mean it’s the actual battery, so be sure to go through the check list discussed earlier to see what the real culprit is. While riding the bike the battery will not charge and if I ride for about 40 miles the battery will be completely discharged. However, it’s important to note that normal riding may not be enough to fully charge the battery … Either it's not charging or the battery isn't receiving the charge . Found my battery not charging. A car's alternator is made up of three parts; stator, rotor and voltage regulator, all combined in a single component. First, you need a battery that is fresh and holds a charge. Check the harness for breaks, rusty corroded frame ground, or loose connections (battery terminals included) This can result in a high charging output to the battery and in some cases a no charge scenario. It’s a pain to pull a battery out of a bike. When the regulator/rectifier isn’t doing it’s job, that could mean it’s not converting the power into voltage the motorcycle can store which leads to the battery not really getting any power at all. You can attempt to start the motorcycle without starting the car since the battery is powerful enough to emit enough voltage to the motorcycle. Here’s how to diagnose, jump-start, and charge your motorcycle battery so you can get on your way. If you get a resistance reading through both ways on the diode. 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. This assumes that your bike has a permanent magnet 3 phase generator, a standard thyristor shunt type regulator rectifier (RR unit), and a 12Volt battery. Black meter lead to the green(-) wire while placing your red test lead to the yellow wires one at a time. Battery – Stores regulated DC current. If you own a motorcycle, chances are that you will eventually encounter a time when it will not start. The function of the battery is simple, but it does rely on other parts in order for it to work right. If the voltage shown on the multimeter is less than 11 volts, your battery should be charged (13 to 13.6 volts is ideal). Once the motorcycle is on, the stator takes over and is what helps the bike run while also recharging the voltage the battery had to use to get the motorcycle started. The “Resources” link explains how to jump start a motorcycle with a dead battery. All I remember was the car was running when it happened. Other features to look for. Record your readings. The car had the later 70 and up electronic ignition … Such add-ons may includ LED lights, phone chargers, etc. Now, if the car is running, that is a different issue. ↑ Most common stator and flywheel combination ↑. Lastly, you can attempt to do a push start your motorcycle since you may not have the battery power to get it started. This model of the 12-Volt motorcycle battery charger offers multiple benefits for a motorcycle owner. Battery charging problems sometimes arise. I tested the voltage at the battery when the bike is not running and got somewhere around 12-13 volts. Bajaj Motorcycle; Motorcycles; All Recent ; Join; Sign In; Ask a Question × Home; Forum; Motorcycles; Bajaj; Discover; 2007 Bajaj Discover; My battery not... Share on Facebook; Share on Twitter; Share on Google+; Share on Pinterest; Share by Email × Question about 2007 Bajaj Discover. Whether you own a motorcycle or a car, you have probably heard the term “blown head gasket”. Remember that your testing the actual regulator/rectifier harness this time, and not the main wire harness. Since these are taking up so much juice from the battery, the battery will drain during a ride and may not be able to start the motorcycle during the next start-up attempt. A low or failing battery can cause crazy readings during your testing. Activating the motorcycle but not fully starting it places strain on the battery. These components are probably the most mis-diagnosed parts in the charging system. As time goes one, batteries have become more efficient in the way they power a motorcycle, but that doesn’t mean they’re flawless. Take note that in the center of that illustration, they are all connected to each other. Do not use a regular charge rate as you would for an automobile battery. This changes the AC wave to a direct (more controlled) voltage signal. With the bike running at operating temperature. 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”. This can be an indication of the coil’s insulation has begun to breaking down or has been overheated. The reading should range between 13.5 volts and 14.5 volts. *Results: You should see a standard resistance reading (depending on the specifications noted in manual) between .001 Ω up to .9 Ω. You’ll also notice any lights become more dim in this scenario. When charging a motorcycle or other small battery, the battery charger should not exceed 3 amps. Ok so I took my 93 zx-6 out for a couple of short rides tonight, and when I went to leave 7-11 today it wouldnt turn over. (The bike does not need to be running to do this test). 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. Checked ac output from stator. There are six diodes total. they will honor their warranty, then we can start with a fresh battery to do testing. Car Recovery, Car Modify, Car Insurance. Thought stator was bad. It may drain the battery on the motorcycle. I cannot remember how but recently I blew the fuse on my multimeter. *Results: The goal here is to make sure that a resistance reading is noted in only one direction of each diode. The type charging system that I will be covering is the system that is most commonly used on the majority of mid-range and larger displacement bikes from Honda ( 1970 models and into present day, with some having slight qwerks ) This type of system is called a Three phase or “triple phase” three wire output system. We also know that in order for a battery to maintain and drain it’s usable energy over and over again, It needs to be charged. Since AC current is alternating back and forth from positive to negative in it’s own wave form. It’s never a good sign when your motorcycle is struggling to stay running while you’re out for a ride. If you want a fast charge with high current, then its best to remove the battery first. Removing the battery is a tricky operation. • With the stator harness connector still unplugged and your multi-meter still in the resistance (Ω) setting, place your red (+) lead to each of the yellow wires while grounding the black (-) lead to a solid ground. When a motorcycle has a bad terminal connection, that means the battery cable either has a poor connection or isn’t connected at all. What you do depends on whether you have power where the bike is parked, and how kaput the battery is – if it’s stone dead, Optimate recommend removing the battery while its desulphation process takes place. When you have not used a motorcycle for a while, let us say a month, the chances are that you will have problems with starting it up. 4. Regulator/Rectifiers.
