Btw if anyone wants to know. The Blue lead and Black lead on the variable resistor are the variable part. When the red and black are used it is a static 5k ohms.
I believe they have 2 different color LED's to indicate polarity. Try reversing the connection and see if the LED color changes.
I guess my question is, can the LED's be used on 12v without fear of blowing them out? In what part of diagnostics would they be used?

I tried mine across a battery. Didn't blow out, just changes colour as you reverse the polarity. You can use them just like any LED test light that will light to indicate a current without drawing the amps that a normal test light would.
One example of use would be if you disconnected a the lead from an injector and plugged in the LED . With the engine cranking or running,you should see the light flashing. It should also increase in frequency as you rev it up.

Can someone explain how to use the various parts in this kit?
1) Do these serve as the red and black test leads for your multimeter ?
Since they connect directly to various connectors and prongs, these replace alligator clips, right?
2) These are just test lead extension cords, right?
3) What is this for? It looks like a splitter.
Why would you want to split one of your test leads?
4) How does this one work? There is a test light on one end.
Where would you plug those 2 other ends? Into your multimeter?
Wait, that makes no sense.
5) There seems to be a rotating dial at one end.
Again, how would you use this?
Where do the other 3 prong plug into?
If you Google the Pots use potentiometer. I always explain them as a dimmer switch. I've used them to test gas gauge problems on older cars.
How would you use the POTS dimmer to test a fuel gauge?
The fuel gauge is measuring resistance, right?
The POT has 3 leads.
What would you connect the blue, black, and red to?
What connectors would the gas gauge have?
4) Ok, so for the test light, instead of the multimeter being in the circuit with the switch and showing voltage, you replace the multimeter with the test light. That way, when the circuit is closed, the light will go on. Right?
in for 1, been eyeing these on my local auction site for several months, they sell 2 or 3 every week but they go for around $45-60 + tax/fees, and gas to go pick it up. $65 delivered is a deal...

I used the kit for the first time to test an auto relay.
I liked how the leads connected to the relay prongs 85 & 86.
Am I using it correctly?
Is there a better way to connect the other end to a power source?
I'd think this kit would come with a male/male coupler?
I used the extension cords, even though I didn't need more length.
It also would been nice to have alligator clips to connect to the battery source.


I was wondering how long it would take for someone to resell this on craigslist for a crazy mark up.
$300 Wow!
