The working volume of which was 494 cm3, and the power was only 6. As the resistance from the sending unit varies along with the coolant temperature, the current at points L1 and L2 will also vary. They can be updated easily to 280 watts. If you want a sketch with the wires in actual color, etc. Clicking on them at every visit helps support this website! Many airheads have a master grounding area, located on the left side of the frame, under the fuel tank, and on many it is at that coil.

There is a complete illustrated article on this very worthwhile and permanent fix for the relay on my website at. Crankshaft sensor: Crankshaft sensor peak voltage: 3. Some alternator repair shops may stock similar diodes. I am doing this because so many seem to have uninformed questions about the starting systems. If you have a bad regulator, you can limp home at much lower than normal rpm to avoid overcharging the battery , with the mentioned jumper in place. Similar items from such as Ted Porter's Beemershop are recommended.
If the lights all come on when the starter is operated. Many an Airhead has voltage drops that are excessive. I use a sharp Xacto knife on a very flat angle, scraping carefully to avoid removing copper material. However, if the place the meter is connected-to is in an area with irregular voltage drops, such as from poor connections, it is not the meter that has failed. Just to be fair, some of the complexity may come from Euro safety requirements.

If the fan does not rotate, inspect: leads and connectors, main fuse, fan fuse, and fan motor. Another possible cause is a bad small diode in the diode board.
Lots of Parts Books, Service, and Owners Manuals for older Hondas. Here it is, in much much more depth, and a bit later a graphical explanation: Ground one side of one heated grip. You can measure the battery terminal voltage, under load, such as the headlight or during starting, that will give you some idea. First, you can check the dash voltmeter's actual calibration. The 1974-5 neutral switches have a shorter stem. Rear Right Turn Signal Light 11.
Front Left Turn Signal Litght 4. If the lamp then lights up, the rotor is bad open. This will fix the problem of a snail spring that is bottoming-out in the slot on the side of the plastic brush holder. They are rated at or above 50 volts, and rated at 30 amperes at 100° C.
