To work it, all you do is to clip the gator to any metal suface on the car and start poking around on the electrical system. A light will come on when you touch a closed circut.

Hope this helps.

Need to know where the positive wires that connect to the battery of a '95 Toyota previa connect.


The black wire will be connected to the body or engine of the van and the red or positive wire is connected to your starter motor.
You can also use a 12 volt battery light to check the negative or positive wires.
You take the 12 volt battery light and place the negative black wire clip to an earth on the vehicle, then when you touch the tip of the 12 volt battery light onto a positive wire the light will light up.
Then you will know which wires are negative or positive sometimes the key has to be on for some wires to work.

I recently bought a 1993 Chevrolet K1500. It had the factory radio in dash, but the cassette player and under dash amplifier were gone. I bought both of these from salvage. In doing so, I noticed a...

Hello! The ALDL or On Board Diagnostic I (OBDI) connector is located under the dash on a 1993...And is different then the 94 you looked at...See diagram below...Is there a wire on "A" and "B"? "A" is a White/Black wire that changes to Black/White at the ALDL connector on pin "A"...and should read to ground..."B" is data and is Orange...These are the two wires that are shorted with a paper clip to get the trouble light to "blink" out a trouble code...I DO NOT see a connection between the fault that you have and the ALDL connector, Although the connector may be missing a wire (easily checked)...LETS SOLVE!!!

The problem appears to be be a lack of a connection to the Yellow ignition wire which could appear White...It's the ACC ignition power to the radio...Just because the lights are on doesn't mean the radio itself has power from the ignition...Also The Orange ignition wire (hot at all times) maintains memory to the radio...The White? wire out out the back of the radio appears to be the ignition wire...If there is already a Yellow wire connected to the radio plug that has 12 volts on it when the key is turned to ACC let me know...

Bottom line...Are there wires in both slots of the under dash ALDL connector??? And is there a splice into the Yellow ignition wire...SEND A COMMENT .saailer


I’m happy to help further over the phone at

The positive and negative clips got cut off my charger and i dont know which wire goes to which clip

Use a multimeter to determine polarity. If there is no "-" sign to the left of the reading, the red lead of the multimeter is connected to the positive wire and the black lead to the negative wire. If there is a minus next to the reading, the red lead is connected to the negative wire.

New blower motor and new resistor. Blower motor still not working. What do I check next?

switch. Use a 12 volt test light at the resistor connector. Take connector off resistor, check the brown/orange stripe wire for 12 volts--is it hot? if yes, connect your test light clip to that terminal and probe the other terminals. Orange/black wire terminal should light up with setting on high. Black wire terminal should light on any setting, etc.

If brown wire with orange stripe is not hot, check fuse 9.
If fuse 9 is OK, problem may be in the mode selector switch.
See diagram and let me know if you have any questions.

How do I check for 120 VAC at the drain pump? I know where the drain pump is, Im just not sure how to check for 120VAC

First you need a voltmeter

Set that to AC volts in the 200v range

Clip the black or blue lead to the earth post (thats the one with all of the green wires clamped on it)

Put the red or brown wire from the meter onto the brown or red wire of the pump (For safety you need to use an alligator clip or spring clip tipped probe to make the connection)

Switch the machine on to the pump cycle and you should read 120v .

Unless you have an electrical background I would not recommed that you work inside a machine which is live.

Installing acoustic research ar94 speakers

Appart from the wire clips what type of connectors are there? are they RCA like on a TV?
If you are driving these speakers with an external amplifier then the red and black cable clips are your safest bet.
these connections are designed to carry an amplified signal. Unlike the RCA connections which are normally Line level.

Wiring a P4M80-M4 mother board

You can download the manual for the motherboard here, just click on the "manual" link:

This will list the front panel connections, which are 2 pins. Each of the jumpers, what you are calling clips, will connect two of the pins. Most cases have the jumpers labeled, i.e. power, reset, etc. But if they are not, it is usually: red/white = HDD led; green/white = power led; red/black = speaker; black/green = power switch; and black/white = reset. But your case may use a different wiring spec, but should list somewhere which wire is for which function.
