Do you need a rectifier on a motorcycle?
Having a functioning rectifier regulator is one of the key elements to maintaining a healthy and reliable motorcycle. The rectifier regulator converts AC power to DC allowing the alternator to charge the battery, and controls the amount of power delivered to the battery.
Can you run a motorcycle without a stator?
NCDave said: only for as long as the battery has power to supply. The stator creates voltage that passes through the rectifier. The rectifier provides power for firing the plugs and also re-charges the battery.
What happens if rectifier is not working?
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.
Does a rectifier need to be grounded?
Re: rectifier grounding
The stock rectifier doesn’t need a case ground. But, some rectifiers need a frame connection to aid the heat sink function.
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.
How many volts should a motorcycle stator put out?
For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18×2). At 3000 RPM it should be 54 VAC (18 X 3).
Can a bad regulator rectifier cause no spark?
A bad regulator/ rectifier will result in a dead battery, and once the battery is competely dead you will not get a spark.
What will make a stator go bad?
There are a few things that may cause a stator to fail. Too heavy of a load when operating accessories (winch,heated grips,headlights, etc). If working several of these items at one time (plowing/pulling/possibly stuck at night) you would overload the system. This could cause either the stator or rectifier to fry.
How do I test my alternator rectifier?
Test a rectifier bridge or a diode trio with an ohmmeter. A diode should allow voltage to pass in only one direction. To test a forward-biased diode, place the positive probe onto the diode and the negative to ground. The meter should read continuity.
Can I use any regulator rectifier?
Yes you can fit pretty much any reg/rec from a modern motorbike with a few exceptions. Honda ones would be easiest because they use the same wire colours (although in a different connector block) so if you connect red to red, green to green and yellow to yellow, you’ll be right.
