thats exactly what I was trying to describe. can the resistors in the kit be used to do that? hooked directly between hot and ground? not sure what the amp load would be like between the min and max? put some load on the circuit and monitor voltage? and not have something melt down?

Thanks!! chris

Resistors are designed by the resistance they are (60 ohm resistor, 120 ohm resistor) along with the watts they are designed to dissapate across the resistor (directly proportional to voltage supplied and the resistance of the resistor in question). To make it easier to understand, an engineer needs to know the system voltage and ohms of the resistor when choosing the proper resistor. I would assume these are 12v resistors designed for automotive use. If that is the case, you should be able to do exactly what youre thinking of.

This resistor would be the load on the circuit. Essentially using this resistor to allow current to flow without shorting it. The maximum and minimum amperage will depend on the system voltage and the max and min of the variable resistor. A 12v system with a resistor that varies from 1 to 10 ohms will provide an amperage of 12 across the circuit in it's lowest resistance position and an amperage of 1.2 across the circuit in it's highest resistance position.

Imagine a resistor as a lightbulb. You apply power and ground to opposite ends of a lightbulb and it uses the supplied electricity, across a resistor to generate light (and some heat). A resistor will do the same thing only it will turn all the used energy into heat rather than light.

Note that I do not have this kit and I'm purely speculating on how it's set up as I scrolled through the pictures and did not notice any variable resistors. Its also 11pm and I havent slept in over 24 hours.

I hope I answered your question sufficiently? Feel free to continue to ask if not.

can the adjustable resistor thing be used to put a load on a connection to see if it will carry a load? my understanding of resistors is fuzzy. I am picturing hooking up the resistor to a hot on a connector, ground it through the ground of the connector. and if I am think right should put a load on the circuit, and you can monitor voltage to see if the circuit can handle amps? kinda like the loadpro leads. is my thinking right?

thanks!! Chris

Those "adjustable resistor thing" aka potentiometer are not designed for the high currents you're talking about. Without going to look at my kit, I would bet those are 2 watt potentiometers, 5 watt at the most. 1 amp at 12 volts is already 12 watts.

To load circuits just use automotive bulbs. An 1157 bulb is about a half an amp on the dim filament and 2 amps on the bright one. For 5 amps, use a halogen headlight bulb.

Finally bit the bullet and bought one. Already paid for itself after one use. My boss fell in love with it, so I'll be putting in another order for the shop.:thumbup:

PM sent to ArchiesToolShop.

Thanks again for the great deal.

Has anyone had issues with continuity of the leads? I have one that is broke between the ends.

Here's me using the potentiometer to test a circuit. The vehicle is a X3 BMW with a diesel engine. The code is for boost pressure signal out of range. With the sensor disconnected, ignition on, probe the 3 wires. One will be 5 volts (red wire), a second will be ground (black) and the other one will be the signal wire (blue). Place the potentiometer to the middle of its travel.

Make sure you turn it off before connecting. I used some of the probes from the kit. With the key on, scan tool connected, I read the value of boost pressure. Adjust the potentiometer up and down until the reading on the scan tool changes. If you get a sensible reading (a value that is possilble) that pretty much verifies that the sensor is bad.

You are months too late, I spoke with Archie and as of July he was all sold out, I attempted to get an additional kit from him. Sorry. You might want to post in the wanted section someone on here may have extras that they bought and be willing to sale to you..

Nevermind, speaking without thinking.

Is he planning on getting more? I pm'd him a while back with no reply.

I PM'd him yesterday but haven't had a reply. So disappointed I missed out on this kit. I posted in the wanted section but if any of you have any extra or if you found you don't use it, I'll very happily pay to take it off your hands!

Used the kit today to test a brushed motor. Hooked the leads right to the motor, connected the leads to an alligator clip attachment. Plugged that right to the car battery and verified motor was fine. So much better than trying to hold 4 leads in contact at once.

Long long sold out.
You might put a wanted ad in the wanted area, some one might have an extra one to sell or have changed their mind and will sell you theirs. Rich

Aw man. I didn't even know this place existed when this deal was gone. Looks like an awesome set. Maybe some day they'll show up again. I'd get one for home and one for work!

this set is badass even at full retail price it would probably be worth it if you do enough electrical work outside a dealer.

This came in handy again today. Powering a small motor. What is this thing called?
I'd imagine there are tons of clones for sale online, but I can't seem to find anything.

The real question that must be answered... Will it work with the HF free multi-meter?



JK nice find! Thanks for the link.
The test leads are the weak link on the HF free multimeter. Mine have fallen apart. I found what look like nice silicone rubber replacements on eBay for around 2 bucks a pair with free shipping from the same place the meters came from. That is about all I can justify to fix free meter

Best to just pitch the HF leads so you never accidentally use them. I've bought a few cheap sets of leads off ebay with no issues, but I don't expect to jump start a car anytime soon with them.

This kit came in handy this week when I had to test a small motor. Love the leads.
What is out there now for someone who wants a test lead kit ?
