Resistance is measured in Ohms with an ohmeter.
because it is broken
Bypass it to determine if that is the problem or test with an ohmeter if you have specs.
Resistance & can be measured with ohmeter.
Resistance & can be measured with ohmeter.
By the National Electrical Code a red wire connects the switch to the load. The only way to be sure is to use a volt meter: one lead to the red wire and the other to ground-the ground wire or metallic junction box; then operate the switch to see volts/no volts. The other wire should be neutral. Check this with an ohmeter to ground. There should be continuity at all times. The hot lead from the switch has to go to the center contact in the bulb holder, and the neutral to the bulb threads otherwise one can get shocked when changing the bulb; again use the ohmeter, but only on unpowered circuits. A volt/ohmeter can be bought for about $10 at a hardware or big box H-W store.
Using an Ohmeter open either end and follow above advice
Take the wire off the injector and use a volt ohmeter to test it. Hook the red or + lead to the wire and ground the -ngeative wire. Have someone turn it over with the starter. If they are getting power the volt ohmeter will register it in pulses.
1.Use of ohmeter. Connect the ohmeter terminals to the the ends of the unkown resistance and take the reading. Adjust the range to give a good accuracy. 2. Use of colour codes. This applies if the unknown resistance is of a resistor with visible colour codes on it.
You use an ohmeter. It sends current through the wire to determine value.
The voltmeter function if the circuit is energized or the ohmeter function if looking for short or open circuits
Just connect a resistor and a small battery in series with the galvanometer,change the markings on the meter's scale, and you have an ohmmeter.
