Yes, a bad regulator will cause your motorcycle battery to be overcharged. This is a common failure because of the way motorcycle alternators work. Measure the battery voltage while the engine is running. … If this regulator fails, then all that extra power gets pushed into overcharging your battery.
What causes a voltage regulator to overcharge?
Improperly jump-starting the vehicle can send a surge through the battery that destroys one or more cells in the battery or shorts it out. This surge disrupts the wiring in the alternator, causing an overcharging condition.
Can a stator cause overcharging?
Anything over 30vac is good. Yes the wires get ver very hot and this unfortunately is normal. If the connector between the R/R and the stator is not making a good connection then the wires can actually get hot enough to burn. It’s impossible for a stator output more voltage then it was designed to do.
What are the symptoms of a bad voltage regulator on a motorcycle?
Bad Voltage Regulator Symptom #2: Your Lights Are Dim
After all, the voltage regulator is supposed to keep the power flowing to the lights, so it’s no surprise that those lights don’t work right anymore once this part goes bad. This issue can extend to your headlights, dashboard lights and even your sound system.
Can you overcharge motorcycle battery?
Overcharging a battery can lead to all sort of problems: The electrolyte may boil, the battery can overheat and buckle the plates and, in extreme cases, the battery may even blow up, especially if excess hydrogen gas is released and there’s a spark handy. … Yes, it’s a pain, but it’s better than cooking your battery.
Can a bad ground cause overcharging?
Ideally, the voltage drop across any connection should be zero or less than 0.1 volts. Poor ground connections are an often-overlooked cause of low charging output and alternator failure. … Voltage drops on the negative side can cause overcharging.
Why is my battery overcharging?
A car’s battery will overcharge if the voltage regulator isn’t working correctly. A voltage regulator is usually part of the alternator, and is used to keep a steady flow of voltage to the battery. … If it sends too much, the car battery will overcharge.
Can a bad rectifier kill a stator?
Can a bad stator kill the Regulator/Rectifier? —-Yes. That is “yes” from an absolute standpoint. Normally no and less likely with the “Y” wound stator used in the DRZ, but yes it is possible.
Can a bad stator cause backfire?
Simply so, can a bad stator cause backfire? The AC power windings have nothing to do with the ignition coils on a stator. Runs good at lower rpms but runs bad at higher rpms (High speed coil is going bad) Backfiring and just won’t run good. Sled slowly loses power during the course of the day.
Why does my rectifier keep burning out?
Other common causes for regulator rectifier failure involve the battery. … If the link is bad and the voltage is faulty, this can cause the regulator rectifier to run hotter than usual. Things like poor grounding, a loose or weak battery, and a worn battery connection can all lead to regulator rectifier failure.
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.
Can a bad regulator rectifier cause no spark?
Yes, a faulty rectifier can cause no-spark condition. … a failed regulator/rectifier will not cause loss of spark unless something is internally shorted in the stator which means it is defective and must be replaced.
How many volts should a motorcycle stator put out?
It should read anything above 12.0v but under 13.2v but ideally between 12.5 – 12.9 DC volts is required. Any less than this, you may start to encounter starting problems as the Battery will not have enough juice to turn the big twin motor over.
Can you leave a trickle charger on all the time?
A trickle charger is a car battery charger designed to be left on a car for a long period of time to re-charge the battery. It slowly adds the charge to the battery and does not allow for the normal depletion of charge that batteries commonly have. … Some trickle chargers can be left on a battery indefinitely.
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.
Can a trickle charger ruin a battery?
Leaving a battery connected to a trickle charger for too long can lead to overcharging, causing damage to the battery. … Although they can’t recharge a dead battery, they can be used frequently and left connected to a battery without any risk of overcharging.
