Hey. I got honda cbr 600, and once i had problems witch charging. I changed stator and rectifier, was good. Now something broke down again. On my stator, between these three yellow leads are 0,01om. Is it good? Maby that's problem with rectifier?

Just what I needed. My battery on my Harley isn`t charging and this step by step method is so much better than the books. Good one!

really great video thanks :) I am new at learning to fix my scooter and I am really enjoying this. My scooter is on it's second regulator in less than 8 months! It is not charging my battery. I tested it today as I run the scooter and used my multimeter on the battery and it did not move up in numbers at all. Sigh. I want to test the regulator now. So I guess I need to take the regulator of the bike or just disconnect it from the bike. Is this correct?
What setting on the meter to i put it?

I don't know without looking at it. If you don't know how to check a battery, than take the battery to your local Honda dealer and ask them to check it for you.

thank you ,, it helps , i have a 1 question i ride a honda xr 250 it has only five wires , 3 yellows and red and green wire. i have replaced a rectifier but still the battery dosent charge , but lights are working good horn is working good as well , do u think do have to change battery as well

We just finished ignition and charging systems. Learned alot. It really is a great school.

What a great video! You just taught the world how to test a rectifier.

Charging system problem. Dead Battery.

I think its becoming more common to see that feature on meters. Thanks for the comment.

**Always follow the instructions in your repair manual when doing repair or maintenance work on a motorcycle. Manuals can be found at the dealer and online.**
Motorcycle alternators produce alternating current (AC) and voltage, and this type of electrical signal can't be used to charge a battery. A rectifier is the part largely responsible for changing the AC signal to direct current, which can be used to charge the battery and run other components of the motorcycle. There are several different rectifier designs, but the rectifier circuit used on most modern motorcycles and automobiles is call a 3 phase bridge rectifier. The circuit is made up of 6 diodes and the diodes are responsible for flipping the negative portion of a AC signal to positive.
The diodes in the rectifier can be checked using a multimeter with a diode function. The meter I use in this video is a Cen-Tech, and can be purchased at Harbor Freight for under $10. When the positive lead of the multimeter is placed on the diode anode, and the negative lead is placed on the cathode, the meter should display the amount of voltage dropped across the diode in millivolts. When the negative lead is placed on the anode and the positive is placed on the cathode, than a 1 should be displaced on the meter, and it means the diode is open and won't allow current to flow. If you get the same response from the diode no matter how the leads are placed on the diode, than the diode is defective and a new regulator/rectifier needs to be purchased for the motorcycle. We are not looking for a specific voltage drop value when the positive meter lead is on the anode and the negative lead is on the cathode, we are only concerned that there is a voltage drop.
