How do I find a short circuit on my motorcycle?
put the ground probe (negative black probe usually) on the disconnected battery wire. check for continuity between all the fuses on both sides. If the continuity(good connection) is good, wiggle some wiring while you test. then if you see a flux on the meter or a high ohms or infinity, you have found the short.
How do you select a circuit breaker for a motor?
You must size the conductors at 125% of the motor FLC [430.22(A)]. You must size the overloads no more than 115% to 125% of the motor nameplate current rating, depending on the conditions [430.32(A)(1)]. You must size the short-circuit ground-fault protection device from 150% to 300% of the motor FLC [Table 430.52].
Will a motorcycle start with a bad Rectifier?
The rectifier is part of the charging system. If you put a freshly charged battery in your motorcycle, and you have a bad rectifier, it won’t stop your motorcycle from starting, but your battery wouldn’t stay charged.
Why do motorcycle batteries die so fast?
All too often, motorcycle batteries die young, murdered by neglect. Dehydration, improper charging, and a slow discharge during storage all shorten a battery’s life. To prevent these draws from killing your battery, you could disconnect the battery, but even if there is no load on them, batteries self-discharge.
What is the average lifespan of a motorcycle battery?
Battery manufacturers agree that on average, a motorcycle battery should last 48 months, yet most of us are lucky to get half of that, and in most cases the battery’s premature death can be chalked up to a lack of maintenance.
Can a completely dead motorcycle battery be recharged?
If you do have a dead battery, you can recharge it with a battery charger (this is preferred), or by jumpstarting your bike with another bike or a car. Once you get the bike running, make sure to ride it for a good while in order to get it fully charged again.
Can a motorcycle battery just die?
The average motorcycle battery will die after 2 – 4 months without running. 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.
How can I tell if my motorcycle battery is bad?
Signs of a bad battery include broken terminals, a crack or bulge in the plastic casing, as well as any leaking fluid or discoloration. Sometimes, battery terminals can become corroded.
How do I check for a battery drain on my motorcycle?
The way to check is to remove the negative battery cable and place your volt-ohm meter in the current (amps) mode. With the key off, place the meters leads between the negative cable and the battery’s negative terminal. The current draw should be zero, but a small drain on the order of a few milliamps is acceptable.
How often should a motorcycle battery be replaced?
According to Motor Gear Expert, a sealed Absorbed Glass Mat (AGM) battery usually lasts from about three to five years. A conventional acid-filled battery has a lifetime of two to five years. If you suspect it’s time to replace your motorcycle battery, the following are tips on how to do it right.
How much does it cost to replace a motorcycle battery?
Depending on power, size, and quality, prices for a replacement motorcycle battery range from $10 to $400. A dealership, parts store, or service center can charge $10 to $100 to install the motorcycle battery. However, many retailers may install the battery free of charge if you buy the battery from them.
How many volts should my motorcycle battery have?
A healthy 12 volt motorcycle battery should maintain a range from 9.5 – 10.5 volts under the load, for a good 30 seconds straight. If the battery begins to hold and then steadily declines, there is a problem.
What is a good voltage for a motorcycle battery?
A fully charged battery should read approximately 12.6VDC. If it reads at or below 12VDC, recharge the battery. Allow battery to rest and test again. A battery that has been fully charged, rested, and tests between 12 and 12.6VDC might start the motorcycle, but it’s not holding a full charge.
How many volts should a motorcycle stator put out?
Tests on the alternator/stator coil with the engine on: Put your multimeter in AC mode. You now can test the voltage between the terminals of the stator coil at 3,000 rpm. Depending on your motorcycle, you should get a reading of anywhere between 20 and 50 volts.
What should a 12-volt battery read when fully charged?
about 12.6 to 12.8 volts
At what voltage is a 12-volt battery considered dead?
Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means it’s about 50% charged.
How long should a 12-volt battery hold its charge?
Most car batteries which are in good condition will last at least two weeks without needing you to start the car and drive to recharge it, according to the AA. But if you don’t intend to drive your car for some time for whatever reason, you should still start it up once a week to recharge the 12V battery.
