Frequent question: How do you check a motorcycle wire with a multimeter?

How do I test a motorcycle wire with a multimeter?

To test it, connect one meter lead to the red wire and the other to either the green or yellow wire, depending on which switch position you want to check. Below is a switch connection diagram for this switch that I’ve drawn for reference. So that’s it. You should be able to test most of the switches on your bike.

How do you check motorcycle wires?

First measure the resistance between the primary wire that comes from the CDI box and the ground or ground wire. The resistance should measure around . 5 to 1.5 Ohms. If that checks out, you can then measure the resistance between the secondary wire (plug wire), w hich should measure in the thousands.

How do you find a short in a wire on a motorcycle?

put the ground probe (negative black probe usually) on the disconnected battery wire. check for continuity between all the fuses on both sides. If the continuity(good connection) is good, wiggle some wiring while you test. then if you see a flux on the meter or a high ohms or infinity, you have found the short.

What’s the best multimeter for motorcycle?

Any 3-1/2 digit DMM (Digital Multi Meter) will do the job. Fluke is well respected for durability so if you find one you can afford you won’t go wrong. One feature that I always find handy is continuity beep; that is, on the resistance (Ohms) setting you can make the meter beep when it reads essentially zero Ohms.

The output from the stator on most modern bikes is three phase (hence the 3 wires) alternating current at a peak voltage well over the 12-14V DC voltage that your electrical system requres.

What is a dead short on a motorcycle?

A ‘dead short’ as pertains to your motorcycle with the stock harness and correct fusing can not cause any damage to the wiring harness, as the appropriate fuse will blow before the wiring can heat-up and melt it’s insulation……… with one exception,;the rectifier is connected directly to the battery and ‘could’ …
