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.

Hi there,

Often, the RED & YELLOW wires are installed incorrectly.

RED............+12 Volt Ignition wire (supplies power only when key is ON)
YELLOW.....+12 Volt Battery wire (this is the wire which retains memory and should be connected to constant power)

If you have definitely installed correctly, then you may have an issue with your head unit.

I hooked up a JVC stero in my 1991 Nissan truck. Now the memory is wiped out for the radio + factory clock when I turn off the car. The radio will come back on, but no presets works.

Chances are that you do not have the constant 12 volt power of the vehicle connected to the memory wire of the stereo. The yellow memory wire of the stereo should be connected to the vehicles' battery. The red accessory wire of the stereo should connected to a switched 12 volt power source.

I have a 14 volt source but when I try the winch in either forward or reverse the voltage drops to 4 volts. The drum is not seized because you can pull the cable out easily by hand.

Not only do you need a 12 volt supply (13.8V) to operate this winch, but you also need a.) wire large enough to carry the electrical load, and b.) a power source that has the necessary current (amps) to turn the motor.

If you have wires that are too small, they will heat up and not be able to deliver the current (amps) required by the motor. If your power source is to small - it can not supply the current required. The result of either conditions is "voltage drop". This can be explained the same way your car needs a 12 volt car battery to start. If that car battery was dead, you couldn't connect eight "D" cell batteries (8 x 1.5volts = 12 volts) together and attach to the car's battery cables and expect it to start. This is because the amount of current available in the car battery is hundreds of time greater than eight "D" cell batteries - even though when the D cells are connected in series - both systems deliver 12 volts.

If neither of the above conditions is present, then there could be an electrical problem with the drive motor itself. This could be a shorted / melted winding or other electrical connection that is not right, even if the drum spins freely.

I can't seem to be able to switch Demo mode of and that, i think is the source of why everytime i turn off my car, all the the settings i've changed come back to what they were. That includes switching off...

Check your Wiring, as it sounds like your Constant +12 volt wire is connected to the Switched +12 volt wire. This would cause all settings to return to factory, just like when you lose power due to a bad battery or battery disconnect. Since you switched off Demo mode, and it comes back, this has to be a wiring problem, or a defective unit, but more than likely a wiring problem. On most pioneer units, the Yellow wire is the Constant 12 Volt (battery) and the Red wire is the Accessory 12 volt (switched).

The radio will not hold memory

If your radio will not hold memory then you are lacking a constant 12 volt power source. Check the yellow and red wires at the radio. The yellow wire should be connected to a constant 12 volt power source (battery) and the red wire should be connected to a switch 12 volt power source (accessory or ignition).

Pcv- rx860 desktop will not boot when power button is pressed, blue light blinking - could it be the power supply? tried re seating hard drive, memory and video cd

I also concur that the power supply is at fault.
Weak voltage power rail.

1) You can check the voltages of the power supply with a power supply tester, (One example:

2) You can also check the voltages with a multimeter.

There are three main voltages produced by a SMPS.
(Switched Mode Power Supply. However the 3.3 Volt power rail is being phased out)

A) Wires with Orange insulation are 3.3 Volts
B) Red insulation 5 Volts
C) Yellow insulation 12 Volts

D) Black insulation denotes a Ground wire. ANY Black wire is a Ground wire. Granted not a power wire, but needed to be stated here with the power wires.

All power cables unplugged inside the computer, power supply still attached to computer case. Power supply is turned on, and the voltages are checked.

Multimeter is set to DC, and the 0-50 Volt scale if applicable.
The Positive (Red) probe lead of the multimeter is connected to a power wire.
The Negative probe lead is connected to ANY Ground wire.

The Voltage power wire of most concern here is the 12 Volt wire.
11 to 13 Volts is okay. Less than 11 volts it's time for a new power supply.
