well welcome back to Steve Robb reviews today we'll go to a little bit of testing and I'd like
to show you a product that I've had for a long time and this is it right here now this comes
in the kit and this is actually the intermittent short indicator tester right here but we're not
going to concern yourself with that today if you like in the future I can show you how that
works but today I'm just going to explain to you an easy way of looking at current on your
vehicle when you're doing some testing and it will show the direction of flow of current on
your vehicle and sometimes it's nice to know especially using the short circuit detector as
well in series is which direction your short is in but for today we're just going to show you how
you can tell whether your circuit is live or if your circuit is not even operating and a lot of
people don't have like an amp clamp they don't want to pierce wires and see if there's a live
circuit or not this is a very easy thing to to use I'll show you right here on the bench very
easy test let's take a look at it well there we go right there there's a unit right here
and this is a very simple device I believe the kit with everything together I bought a couple
years ago maybe 10 years ago was like 25 bucks and really all it is is just a glorified magnet
but it's got a needle on there and it'll show you the direction of current flow so what we're going
to do here is I just have an 1157 bulb here and of course we've got the positive cable and we've
got the negative cable so all I'm going to do is just place it over top and you will see how this
thing works terrific and then I'll take you out to my truck and I'll show you a perfect example
a real a real good idea that may be practical in the future for all of you so I got a power
supply here I'll just turn the power supply and the that's pretty bright a so I'm just going to
put that over top of here so it's not too bright and what we're going to do now is I just want you
to watch that needle can you see the needle move see how that's moving in that direction this way
and that's from negative to positive and I come over to this side and you could see it's moving
in the other direction now it's not moving a lot maybe you can't see a lot on film but it is moving
and it is moving in direction so as you can see over here further away from the load it's more
amplified and most of the time you are away from the load so let's go out in the in the driveway I
got my Silverado there and I'm going to show you a real simple test that may help you out too before
this burns the glove apart okay so we're out in front of the Silverado here I'm going to do a
basic down-and-dirty test whether the headlights are going on or whether the marker lights are
going on now this is just a basic test that's just showing that this little tester can tell
whether there's current flow going now obviously you go look at the headlight and see that it's
on or it's off but a lot of times you're going to run into a situation where take for instance it's
going off and on sometimes and you want to know which direction of flow it is or sometimes you
have not such an obvious load that is actually going on but it's not being activated somehow
this will actually show if you have current flow and that's all this doing is showing if you have
current flow or not so let's take a look okay so what we're looking at right there is I put the
device right on top of the positive cable doesn't really matter if you pick the positive cable or
the negative cable but I just picked the positive cable for now just for demonstration purposes and
all I'm gonna do is reach inside here and just turn the marker lights on now did you see that
move a little bit there I'll turn them off I'll do it again okay now I'm gonna turn the headlights on
you see that move turn it off turn it on turn it off now I'll turn the headlights on there you go
okay so what was the purpose of all this well the only purpose of this was don't get that to
stop wiggling there is this little device which is more or less just really a magnet will show
the direction of current when you're using it with the little circuit breaker that comes with the kit
or just using it on its own like this just to see whether you have current flow or not and a lot of
times that's not so easy for a lot of people they don't feel comfortable you know with having all
the amp clamps and digital meters and everything else this is just a simple test you know I'm not
trying to diagnose anything out here I'm just showing you how this actually works and I think
it's a great addition to the toolbox I don't know if you can buy this separately or whether
you have to buy it as a kit but I think it's a terrific item you know it's just quick and it's
easy and it verifies whether you have actually something being activated on or not if there's
current flow and I think that's just a you know a basic part of Ohm's law and you know what it's
it's not rocket science I'm not trying to teach anybody anything I'm just showing this product
and what it can do so thanks for driving me here today and I hope you like this a little bit of a
demonstration on this kit and I think it's a good review of showing stuff like this that maybe a
lot of people might be interested in so thanks for joining me here today you haven't seen this
channel before well you're welcome to subscribe these guys take care come back again now Cheers
