How to test the charging system on a Harley Davidson?
Charging System Voltage Test Start motorcycle, measure DC Volts across the battery terminals (you should have a reading of approximately 13.2-15 DC Volts). 3. Check Connections/Wires Inspect the regulator/stator plug, and check the battery terminals for connection/corrosion.
What should I do if I get a reading on my stator?
Set your multimeter to Ohms. Put the negative lead on the engine’s ground and the positive lead on each wires of the stator’s connector one by one. You shouldn’t get a reading at all. If you get a reading, even very small, on any wire, the stator is defective and must be changed. Put your multimeter to AC Volts and start you vehicle.
Where is the stator cable on a grizzly?
Locate the regulator/rectifier under the right rear fender and disconnect the stator cable from it. The stator cable is the lower of the two cables, attached via the gray connector. Step 2. Set your multimeter to ohms, and connect its negative lead to a ground source such as an exposed bolt or the negative battery terminal.
What happens if the stator on a grizzly goes bad?
If the voltage checks out, the next step is to test the stator, which is the component that generates the electricity your YFM700 relies on. A faulty stator means no power for your ATV. Watch the video above and follow the guide below to test the stator for your Yamaha Grizzly.
What should the charging voltage be on a Harley stator?
You can use 13 as a good all around battery voltage. That is a good healthy battery staying charged just above 12 volts. Example only: Let’s say the stator is rated for 10 amps x 13-volt battery: 10 x 13=130 watt charging system. So you have a 130-watt charging system in this example.

Where does the Black Wire go on a stator?
The 3 yellow wires connect to the stator. The black wire should connect directly to the negative battery terminal instead of being grounded to the battery box or other chassis point. This helps cut resistance in the charging system. Newer replacement r/r units may have a 6th wire, called the “sense” wire.
What are the output wires on a stator?
Like The Stator Papers suggest, just consider all of the stator output wires as yellow in color. Below are the stator output wires in my hand. The stator outputs are labeled “A”, “B”, and “C”. I have also pointed out the wires leading to the regulator/rectifier unit. Stock r/r units have 5 wires. The 3 yellow wires connect to the stator.
How to check the AC output on a Harley Davidson?
AC Output Check: 1 Unplug the regulator plug from the stator. 2 Start motorcycle and change Voltmeter to AC volts. 3 Probe both stator wires with your meter leads. 4 The motorcycle should be putting out approximately 18-20 ACV per 1,000 rpm. (Reading will vary depending on system, check service manual specifications) 5 Generic Specs:
How can I tell if my motorcycle charging system is working?
So you have a 130-watt charging system in this example. Now, you can take the wattage of all those electrical accessories and see if you’re under or over your 130 watts and how much you have to play with. You can check your system by putting a volt meter on your battery. Or add a volt meter gauge to your motorcycle.
How to do an IB test on a Harley Davidson?
Stator IB test or Ground Check: 1 Switch your multi-meter to Ohm x 1 scale. 2 Probe each stator wire with your positive lead on multi-meter and the negative to ground. 3 There should be no continuity to ground on either wire. 4 If there is continuity to ground, your stator is shorted to ground.

Where can I test my Harley Davidson battery?
Most places like Auto Zone, Advance Auto, and Pep Boys will charge and test motorcycle batteries for free. Standing battery Voltage should be 12.5-13.2 DCV. 2. Charging System Voltage Test Start motorcycle, measure DC Volts across the battery terminals (you should have a reading of approximately 13.2-15 DC Volts).
How do you test a 12V motorcycle battery?
Let it sit for at least an hour after disconnecting it from a charger. Turn on your ignition so your headlights are on and other accessories for about two minutes and then turn the ignition off. This is to get rid of any surface charge. Place the voltmeter leads to the battery terminals. (positive to positive and negative to negative).
How big of a battery do I need to charge my bike?
This is why many 5000mAh+ batteries don’t charge particularly well from dynamo hubs. That said, if you’re cycling at speeds over 25km/h, or you use one of the powerful USB chargers, you can sometimes charge batteries up to 10000mAh – but I’d still recommend 2x 5000mAh batteries instead.
How to test the battery on a Harley Davidson?
Place your multi-meter positive lead on each AC output wire. Place your multi-meter negative lead on the battery Charge wire. The meter should read voltage typically around.5 volts. Next, switch your multi-meter leads putting the negative lead on the AC output wires and the positive lead on the Battery Charge Wire.

What should my motorcycle charger voltage reading be?
You’ll want to see a reading of 13.8 to 14.5 volts to know that your stator and regulator/rectifier are operating properly and charging your battery. If not, then you likely have a motorcycle charging system problem. Consider keeping your motorcycle battery on a simple inexpensive battery tender that just plugs into a wall outlet.
Is it better to test a charging system in a car?
An in-car test is actually better than taking parts off. I hope this helps people avoid wasting money on parts. Here’s how we can check a charging system with a few simple pieces of equipment. Basically, you just need a test light and small test meter. I have a full diagram of the 1989 Mustang here 1989 Ford Mustang Wiring Schematic

What should the charging voltage be on a car battery?
Charging voltages over 14.7 volts can prematurely dry the battery by boiling out electrolyte, and increase risk of a battery hydrogen gas explosion. In this case the battery charging voltage is 14.61 volts with the engine at high idle. 14.4 volts is the gassing threshold.
The battery terminal charging voltage must be less than 14.7 volts to prevent excessive gassing. Charging voltages over 14.7 volts can prematurely dry the battery by boiling out electrolyte, and increase risk of a battery hydrogen gas explosion.
Is the Samsung Galaxy S20 Ultra a fast charger?
The Samsung Galaxy S20 Ultra comes with a fast charger in the box, but how quick is that charger really considering that it has to recharge a gigantic, 5,000mAh battery? We have measured the Galaxy S20 Ultra charging speeds using the adapter in the box, and we came away impressed with the speed.
