Check battery contacts and make sure that batteries are in correct position - other than that you will have to return unit for service

Remove battery from FLHR 2009

Hi Anonymous, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12 volts or better after charging.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to:
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor. Good luck

Get your battery charged up to full charge and put it back in the bike but leave the negative battery cable loose. You'll need a digital volt ohm meter that will measure at least ten amps of current. Pull all the fuses out of the bike and leave the switch OFF. Set the meter's function selector switch to AMPS. Plug the meter leads into the meter with the red wire in the AMPS hole and the black lead into the COMMON hole. Connect one lead to each clip where a fuse goes in. This wires the meter in series with the circuit, replacing the fuse. Hold the negative battery cable onto the negative battery post. The meter will tell you how much current is flowing through the circuit. If the reading is a negative number, reverse the meter leads where you have them connected to the fuse holder. This will tell you which circuit has the current draw in it. From there, you'll have to refer to a wiring diagram to determine exactly what is on that circuit. The reason you leave the negative cable loose is if you short something, you can disconnect the battery quickly if you have to.

Good Luck

Remove the covers inspect all connections need to test ( remove red and black leads ) the battery with a multi meter to see if you have 6.1v if not replace the battery. If battery is good then check the alternator, unplug the unit and also leave battery unplug .
Locate and remove the black wire from the B+ terminal on the alternator ( larger nut then the others across from the brown lead) . Remove brown lead from the field terminal on the alternator. Place a short with alligator clips on the B+ and field terminals of the alternator.
Step on the machine for approximately 10 to 15 seconds, if the full resistance , if not then replace alternator. if alternator is good then check the load resistor with a multi meter resistance needs to read 2.5 ohms if not replace resistor.

1985 dodge powerwagon, lights went dim driving home now wont start, just replaced battery 6 months ago. starter clicked at first then nothing.

The alternator may not be charging the battery. Jump start it, and use a volt meter at the battery, red lead to positive and black to neg. The meter should read between 13 and almost 15 volts, any lower than 13 volts, the alternator is no good. (this is done with vehicle running).

Is the fan belt tight? If so using an amp. meter, start engine & check by putting leads on neg. & pos. of battery. Reading should be higher than 13.2 if lower replace alternator. Good luck!

Fluke 8060AA digital multimeter

The fuse has nothing to do with the display.

The contacts of the LCD are probably oxidized because of its age. With the unit out of its care, carefully remove the LCD from its retaining mount. Use rubbing alcohol and a clean q-tip to clean the contacts of the LCD and the small "rubber-like" strips that contact both sides of the LCD. Also, remove the strips and clean the other side and the contact on the main circuit board. Then reassemble.

*Note, if you live in a cold climate, freezing of the LCD could also cause this problem. In that case you must purchase a replacement LCD from Fluke.
