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?

Re: Sanwa 460-ED Multitester
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.

what you need is either continuity, the symbol for that is a solid arrow, or you can check the resistance by using the ohm's setting. the only difference between the two is that, when using continuity setting if you are reading it, it will beep if in fact the device you are testing has continuity. with ohm's no beep, but with ohm's if you read ol. or ul. that means infinity, meaning no continuity. so whatever the specs are for the device in question that you are working on, numbers will come up. hope this helped
How does it work when cold? Like normal? Or are there problems or slippage then too. As the engine warms up, so does the transmission. As the temp. rises, so does resistance in things like shift solenoids, lock up solenoids, etc. This makes it harder for the computer to make the solenoids work so, this could be the problem. You should have some sort of trouble codes associated with that type of failure. If you have no codes, it may be mechanical. Possibly clutches worn out. I hope this helps you out. Good Luck!!!
Check for spark at the spark plugs. If you have spark, the the problem is fuel related. If your carbs have an electrical solinoid below the bowl, unplug the wire connection and THEN unscrew the solenoid. There maybe a fiber gasket, be careful not to tear it. Unscrew the solenoid and check to see if clean fuel comes out of the bowl. If no fuel comes out, you have to clean the carb bowl and the jet. If clean and FRESH gas does come out of the bowl, then the (fuel shut off) solenoid is stuck in the OFF position. (the alcohol in our gas causes these solenoids to rust and stick) Buy a new solenoid. NOW if you don't have spark, check the kill switches first, you may have 3 on a riding mower.You can temporaily bypass them if you don't have an ohm meter for testing.
it will have to be replaced. any repair could change resistance if checking ohms and change any readings it will take. look up ohms law online and it will explain the relationship between voltage,amperage, and ohms
there are several reasons why the tester doesn't react..try to check these:
1. Check the safety fuse inside it.
2..The test lead set (the red & black wire w/ pin )
might have cut inside it,particularly in the part of
ends,near the pins/plugs.
3. The bateries might be o voltage and need to be
replaced.,or if the batery is good,just clean the
contact or teminal of the bateries.( a common
multi tester have 3 bateries, composed of 2 size
"AA" & 1- 9volts size.) these bateries are all
assigned to the "continuity"section of the tester.
(these are: X1;X10;X100 ; X 1K & X10K. )
so,if the tester is not functioning only in that
section,the first thing you have to check are the
bateries.Now.if you replaced the bateries with
new one but it is atill not working,then we go
back to my tip number 1 above.,that is to check
the test lead.
3. if you already finish checking the above method
and it still not working,then there is a problem in
the resistors of the system.
But, is your tester is digital? if it has no power: just simply check the fuse & batery..But if it has a power but not working when you use to test,you jst check the test lead or the selector switch becos the contact inside might be loosen.
We use floor sanders ...or rent the units at Home depot ... Clarke floor maintainer, with appropriate discs ... 60 - 80 grit 17" disc... you may need more than 1 depending on size of job. They have finer grits available also ...30-35 bucks a day ... and they have 1/2 day rentals too.
