Can a regulator rectifier drain a battery?
In general, there are two primary ways that the regulator rectifier can fail. First, the diode can burnout and cause the battery to drain. around 13 volts, the bike will start to drain the battery. When this happens, it’s only a matter of time before the engine stops completely.
Why is my Harley draining battery?
There are several reasons why a motorcycle battery drains while riding including a bad battery terminal connection, corroded battery terminals, a bad stator, a bad rectifier/regulator, too many electrical add-ons, too old of a battery, and if you have a newer motorcycle, an automatic shut-off will happen if the battery …
How do I know if my Harley voltage regulator is bad?
Bad Harley Voltage Regulator Symptoms
- Power Failure. One of the simplest ways to notice a bad Harley voltage regulator is when the cluster cannot power.
- Gauge Flickering.
- Malfunction in engine light.
- Error reading the cluster.
- Brown headlights.
- Gas fusing out of battery.
- Faulty voltmeter reading-
Will a motorcycle run with a bad rectifier?
A rectifier converts alternating current (AC) to direct current (DC) to charge the battery. Since motorcycles require battery power to start them up, a bad rectifier will eventually result in the motorcycle not able to start.
Will a bad rectifier damage a stator?
If the rectifier/regulator failure results in too low resistance the stator probably will burn (too much current). If I disconnect the rectifier/regulator the voltage will go up, but how high? Is it possible that the voltage will go high enough to destroy the isolation?
Will a bad stator drain your battery?
Will a bad stator drain a battery? As far as the battery, yes a bad stator/regulator can destroy a new battery. If it’s run at a very low voltage without being recharged then it can be destroyed.
How many volts should a Harley start?
This is normal because the motorcycle draws current from the battery in order to start. Once the motorcycle is running, the voltage reading should be between 13.6 to 14.5 volts. The noticeable jump in the voltage is a result of the alternator (or generator) charging the battery.
How long do Harley voltage regulators last?
between 50,000 and 100,000 miles
How Long Do Harley Voltage Regulators Last? A Harley Voltage regulator is expected to last between 50,000 and 100,000 miles, providing the battery is well-maintained.
Can a motorcycle run without a regulator rectifier?
Can I ride my bike without a rectifier? – Quora. If you mean the rectifier diode bridge that is part of the battery charging system; Yes , the engine may start and run with sufficient reserve battery capacity (voltage and percentage of charge remaining).
