Test the Battery
HARLEY DAVIDSON ELECTRICAL PROBLEMS

How to Test the Battery & Voltage Regulator on a Harley Davidson

Some Harley owners like to fix their own bikes, thereby saving both money and riding time. A Harley Davidson can experience electrical problems at any time, but there can be a wait for a service appointment at some repair shops. The most common cause of electrical problems on a Harley Davidson is the battery or the voltage regulator. Troubleshooting can be performed in any garage, and it saves on expensive service bills.

1 Check the voltage of the battery while it is disconnected from the bike using the multimeter. The volts should be no less than 12 volts.
2 Connect the battery to the bike. Reconnect the multimeter to the battery.
3 Turn the ignition to the "on" position. Do not turn the engine over. The volts will drop slightly, but not below 10 volts.
4 Turn the ignition and start the bike. The volts should not drop below 9.6 volts when the starter engages.
5 Turn the throttle to rev the engine. As the engine is revved, the volts should go up to 13 or 14 volts.

Test the Regulator

6 Identify the wires. The battery charge lead runs form the voltage regulator to the positive side of the battery. The AC output lead wire leads from the voltage regulator to the stator.
7 Check the ground wire first to ensure that it is properly attached and in good condition. The ground wire leads from the regulator and is bolted to the frame.
8 Secure or replace as necessary.
Test the Diode Function of the Voltage Regulator

9 Change the setting on the multimeter to Diode. If any of the following tests fail, the voltage regulator needs to be repaired or replaced.
10 Clamp the multimeter positive lead on the AC output wire and the negative lead on the battery charge wire. The multimeter should read .5 volts.
11 Reverse the leads by clamping the negative lead on the AC output and the positive lead on the battery charge wire. The meter should read infinite.
12 Place the positive lead on the ground wire or on the regulator and the negative lead on the AC output. The meter should read .5 volts.
13 Reverse the leads as in the step before and test again. The meter should now read infinite. Reverse the leads as in the step before and test again. The meter should now read infinite.

TIPS & WARNINGS
Any battery or voltage regulator test should be done on a fully charged, fully functional battery.

Instructions     How to Check

The voltage regulator in your motorcycle has the duty of preventing your battery from being overcharged, as well as ensuring that the proper voltage is being supplied to your bike's other systems. A weak or dead battery is often the first clue that your voltage regulator is faulty, preventing the battery from being recharged while the motor is running. Luckily, testing the voltage regulator is a fairly simple task.

Set your multimeter to 20 volts DC (Direct Current) and connect the positive (+) and negative (-) leads to the corresponding battery terminals. Your battery should be charged, giving you a reading at or just above 12 volts

Start your motorcycle and rev the motor to 5000rpm, maintaining the engine speed during the testing.
Using the multimeter, test the battery terminals again. A constant reading of 13.5 to 14.5 volts should be present. This is the proper voltage that will allow the battery to recharge properly.

INSTRUCTIONS

The first thing you will need to do is identify the different leads on your regulator and orient your circuit breadboard.

1       Hold the 7805 voltage regulator so that the printing is facing you. The lead on your left is the input lead. The middle lead is the ground. The lead on your right is your output.

Now, take your breadboard and lay it flat on your work surface so the length of the board runs from left to right and the shiny side is face down. The board is separated into three main areas. What we will call the bottom of the board is a series of holes that form a narrow rectangle and run from the left to the right. A similar series of holes runs across the top of the board. Both of these are referred to as "terminal strips." In the center there is a series of holes, also in a rectangular layout, but this layout is much wider then the ones on the bottom or top of your circuit board.



Place the breadboard on your work surface so the length of the board goes from left to right. Connect the ground wire of the transformer you want to use for the voltage regulator to one the long outer strip of the breadboard nearest you. Consider this the bottom of the breadboard.

2
Take the 7805 voltage regulator and plug the output lead of the 7805 into the strip of holes at the top of the breadboard. The remaining leads, the ground and input should plug into the center area of the board.

3  Connect the ground from the bottom terminal strip to the ground (middle lead) of the 7805 with a jumper wire.

4 Connect the positive wire from the transformer to the input of the 7805. Remember, the input of your 7805 is the lead on the left if you are holding the 7805 with the printing facing towards you. Even if you use a different size or style of voltage regulator, the standard of manufacturing is that the printing is always on the same side to make identification of the leads possible.

5 Now take your capacitor. Capacitors have both a positive and negative terminal, only one of them will be marked. A negative terminal will be marked with a (-) and a positive terminal will have a (+). Identify the positive terminal of the capacitor and connect it with the input lead of the 7805.

6 Connect the output of the 7805 to the long outer terminal strip at the top of the breadboard.

7 Connect the second capacitor between the output and ground leads of the 7805. The negative lead of the capacitor should go with the ground of the 7805 and the positive with input lead of the 7805.

Tips & Warnings  
Use a multimeter with a thin electrical wire attached to the lead to test the breadboard to make sure the holes you are plugging your leads into are connected on the reverse side of the board. The resistance measured will be zero if they are connected

Do not introduce more than 30 volts to this form of voltage regulator or you will burn out the components.



Editorial from a forum Virago XV400



This is a editorial I read on a Forum, very interesting reading about the Virago xv 400 

 

The VX400 was made for the Japanese domestic market. Exactly the same bike as the VX535 except for the displacement. VX535 was the export model to the US and Europe.
There are also two models of the VX400. One with the fake tank, and the other with a real tank connected to the tank under the seat, the more desirable model. Easier to fill up with the real tank model. No need to open the seat, etc. The fake tank model is better for customizing, since you can install dials and gauges on the fake tank.
The VX400 is very popular here in the Philippines, as with the Honda Steed 400.
I have restored and customized seven VX400 in the last three years.
A very simple bike to work on. Very mechanic friendly (as compared the the Honda 400 Steed). The VX400 came out in the late 80's and until Yamaha stop making them in the late 90's not much has changed on the bike. Minor cosmetic changes from year to year. Lots of spare parts available in the surplus market.
One of the few bikes I know where you can overhaul the carburetor without taking it off the bike. You can reject a VX400 in 10 minutes, while it would take two hours on a Steed and a couple of bruised knuckles. If you enjoy working on your own bike, this is the bike for you. Very low-tech. No radiator, not oil cool. Screw type valve adjustment, no shims needed.
Also the drive shaft with proper maintenance will last the life of the bike. The downside is that you are limited to the size of you rear tire you can put on when you customize without modification of the swing arm.
