Each terminal has a specified power source it uses. if you have one from another terminal it may not work for this one. the power sources should not be swapped out. if you have a specific terminal i can determine the power supply it requires.

Haier LE50H3280 will not power on


If all power supply voltages are within specs, then it just might be an issue with your main board,.

If PS board has a relay make sure that it is also working.

How to wire cardone 40-3025 wiper motor to 12 V power supply


The ground terminal should be easy to find. Connect your VOM or continuity tester to each terminal on the motor one at a time and touch the metal housing of the motor with the other. when you get a complete circuit you found the ground or negative terminal. Connect the 12V negative from your power supply to this terminal. Bare the other wire from your power supply and momentarily touch to each of the reaming terminals in turn. When the motor turns thats the correct one.

Can't supply a diagram but I can tell you that 15A fuse 27 in the central junction box (CJB) applies power via a LT BLU/PNK wire to terminal 2 (the coil) of the indicator flasher relay in auxiliary relay box 1. 20A fuse 18 in the CJB applies power via a LTGRN/RED wire to the brake pedal position switch and terminal 3 (the relay arm). Terminal 5 of the relay connects the relay coil to ground (BLK wire). Terminal 1 of the relay supplies power via the LT BLU wire to the turn signals when the relay is closed. Terminal 4 supplies power via the WHT/RED wire to the hazard light circuit when the relay is open.

T101r just installed by licensed electrician. On off switch does not operate. Power is continuously supplied to timer. On Off pins do not operate. I must control power from gfi attached to house or breaker...


I have this timer. The clock should run continuously in order to keep time.
The ON/OFF switch should turn the load (lights, pump, etc.) on and off.
If it doesn't, either the device is defective or it is incorrectly wired.
The wiring should be:
The 120 volt supply white wire connects to the A terminal.
The 120 volt supply black wire connects to the LINE terminal.
The load white connects to the A terminal.
The load black connects to the LOAD terminal.
The clock wires area already connected to the A and LINE terminals.
Let me know what you find.

How do I wire my GE 15306 timer to 1 110 volt line so it will work?


The Black hot wire from your house supply goes on the terminal below the L and 1.

The White neutral wire from your house supply goes to the terminal below the X.

Connect a White neutral wire from the terminal below the X to your neutral on your load.

Connect a Black wire from terminal #2 to the Black on your load.

This wires up both your timer clock and will turn on your device, too.

No power to my pioneer gm5300t


arcanum,

good day bro, from your Pioneer amp supply line do you also see a terminal marked as " System controller" ? did you also supply 12V DC to this terminal?

the standard power configuration for Pioneer Car amps would be:

12V Dc (+) supply / ( - ) supply ground / System Controller ( supplied by +12V DC)

12V ( + ) supply and The ( - ) supply ground is for stand by power, once you connect the supply through this terminal you will now have the stand by power but will not power on the unit even the LED power indicator.

System controller terminal, this should be supplied by ( + ) 12V line to power up the amp. this serves as the ON/OFF switch for the amp.

cheers,
mark

SA HE200 ~ Overload at power up


First of, be sure volume is turned all the way down before or as you are powering it it.
Second if that does not work disconnect all speaker, and input/outputs.  Power the device on and see if it says overload.
If it does skip the rest of these steps, your capacitors are bad or the power supply is no longer functioning correctly.
If it doesnt, start with testing each speaker at power up.  Match the speaker to the output it goes on, power the device see if it says it. 
If it does on any speaker test it is a speaker issue or a terminal issue.  To test for terminal or speaker issue plug a different/ known to work speaker in that same terminal, if it doesnt say overload it is a speaker issue, if it does say overload it is a terminal issue.
Once you have made sure all speakers and terminals work correctly start plugging input and outputs in and test individually.

I'm not sure that there is a car charger available for the GPS 310. There is no external port where you could plug it in, the only thing you can do for power is take extra AA batteries with you.
