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.
How many volts should my regulator put out?
The voltage output reading should be about 0.5 volts higher than your battery’s open circuit voltage. Most voltage regulators are calibrated to output between 13.5 and 15.5 charging volts on a fully charged battery at normal temperature with no accessories or lights on.
Can a voltage regulator short out?
Engine stalling, sputtering and intermittent acceleration will occur when the vehicle’s voltage regulator is unable to handle the power put out by the vehicle’s stock (and faster-moving) alternator. This causes the regulator to burn out quickly because it was overworked.
Will a motorcycle run with a bad voltage regulator?
There is a wide range of possible reasons your motorcycle’s regulator rectifier could fail. A faulty regulator rectifier could not only affect things like motorcycle values but will impact the bike’s performance on the road. One of the primary causes of failure is heat.
Can a stator put out too much voltage?
So first off it’s not possible for your stator to ‘ feed too much voltage ‘ to the regulator….. and your bike does not have a rotor that can be ‘checked’. The charging system on your bike consists of a stator ( which is a wire winding in segments ), a field coil and the rotor which spins between them.
What are the symptoms of a bad voltage regulator on a motorcycle?
Symptoms of a bad motorcycle charging system
- Motorcycle won’t start. This one’s the big, obvious one.
- Spluttering as you drive. When voltage is low, it’s hard to keep the motorcycle running.
- Lights light up and dim as you rev.
- Battery warning light comes on.
When to replace voltage regulator on motorcycle battery?
This is the proper voltage that will allow the battery to recharge properly. Replace the voltage regulator if the reading is higher or lower than the 13.5 to 14.5 volt range to prevent insufficient or excessive charging.
Where does the regulator go on a motorcycle?
In this system, both the ends of the winding go to the Rectifier section which converts AC to DC voltage and then the Regulator section regulates to 14.4V as discussed above. 4) 4-pin Regulator (B): This is the most common type found on motorcycles with single-phase winding.
What causes the regulator on a bike to fail?
Depending on where your bike’s regulator rectifier is located, the part can overheat. When it overheats, the component could fail fast. Other common causes for regulator rectifier failure involve the battery.
How does a bike regulator rectifier work?
Some bikes have single-phase designs because they cost less to manufacture, in which case there would be two wires rather than three. In any case, the regulator rectifier converts the AC power into DC power, then regulates the DC power to ensure that the power doesn’t go over around 14.5 volts.
