Signs Of A Bad Voltage Regulator Motorcycle
Olivia Luz
A damaged or failed voltage regulator can rapidly diminish the alternator s ability to cycle power from the battery.
A good way to tell if this is happening is to check the battery cables for excessive heat. Generally readings above 17 volts mean the regulator rectifier is not converting excess power. The charging system of the motorcycle should bring the voltage of the battery up to about 14 2 to 14 8 volts. This may cause the vehicle to experience dimming or pulsating external systems such as headlights and dashboard elements.
You ll note signs right away like poor starts fluctuating meter readings and dimmed headlights. Dimming or pulsing lights. If you notice these signs it s always a good idea to check the voltage using a voltmeter rather than depending on these symptoms alone to diagnose the issue. Anything over that and the system is overcharging.
One of the first symptoms you discover when your harley voltage is going bad is that your bike s gauges show dim or flickering signs. The voltage regulator is responsible for supplying power to the gauges and once it has a fault the gauges start to shine dimly and the indicators flicker at intervals. This can cause the battery to overheat or even explode. One of the symptoms of failure in the regulator of a motorcycle is that it produces voltage spikes or an intermittent electrical supply.

Should the regulator rectifier fail to control voltage the result will be battery overcharge. And is no good if the stator shows good and you have a new or fully charged battery start the bike and check standing voltage at idle it should be in the upper 12 s to mid 13 s now turn the brights on and slowly raise the r s till you hit about 4500 5000 and you.
