Question about Measuring Tools & Sensors
Hi I am trying to test the resistance on my vct solenoid, and needed a ohm tester. I have a Sanwa 460-ED but have no clue how to use it, no instructions. I am trying to find out what exactly it tests, and if it is a dohm or what it is. Can i use it to test the resistance? and if so how do i do that?
I am not familiar with that particular meter but.... to measure resistance you will need an ohms scale.
the leads should be plugged in to the + and - holes. Normally the red lead always goes in the + lead.
If there is a switch to change scales, do the following. Touch the ends of the test lead together, (after you have connected the leads to the meter. Rotate the switch thru all of its positions. if you see the
meter swing over towards zero, that is the ohms scale position. There should be a knob to zero the meter when the leads are touching.
Come back with any questions and I'll respond Loringh

Use a continuity tester or multitester to test for continuity. Set the multitester to the ohms setting X1. Touch one probe to each terminal. A reading of infinity indicates a bad solenoid that must be replaced. Different brands and models will have various measurements, but the valve should show some resistance if it is functioning properly. Test the second one in the same way as the first.
If the solenoid is working properly, but water leaks through the valve even when the washer is off, then the valve itself is the problem. Debris may be preventing the valve from closing. If the valve cannot be cleaned, it will have to be replaced. The valve can also fail mechanically. So even if it passes the electrical test, it may still require replacement. If you have ruled out all other possibilities, go ahead and replace the valve.

With the probes still in place, turn the relay over. You should hear the click of the magnetic switch engaging. The multitester should now display an ohm reading of infinity (or the tester should not light up).
Turn the relay upside down again, place the probe on the "S" terminal and place it on the side terminal labeled "L".
The multitester should now display a reading of zero ohms (continuity). Turn the relay over and the reading should change to infinity.
With the relay upside down place one probe on the "L" terminal and the other probe on terminal labeled "M".
The multitester should display a reading of zero ohms. Turn the relay over and the reading will stay the same, zero ohms.
If the compressor relay does not pass all of these tests, it should be replaced
