Not sure what you mean, power from relay? Make sure when you test for power you test to ground as well as the neutral wire. In some cases power is detected on the neutral from a back feed.

I need a wiring diagram for a 2000 Toyota Echo A/C compressor clutch.

relays work y having two circuits
one circuit comes from the triggering device, switch , climate control module ,thermostat which supplies 12 volts to a internal coil then out to ground
When that is achieved the coil closes a set of points
The second circuit is the high current circuit which allows the heavy current draw to pass through the points on to what ever it powers ( AC clutch in this case
If the points are not closing , then either the coil is faulty or the ground wire is not completing the circuit

Need a/c wiring schematic for 2007 peterbilt 386

First is there power at the CONNECTOR to the clutch? unplug it and run the vehicle, with a Volt meter, ground the black lead, and check the pins on the connector for voltage with the AC controls set to ON. if there is 12-14 volts on one pin re check with the control set to off. if the voltage goes away at the connector, it is a switched POWER system, and everything is fine with the controls and you found the correct power lead. NEXT set the meter to OHMS and test the connector again with one lead grounded and (DO NOT TOUCH THE POWER PIN or pins, which is why you check for power first) and look for the one that grounds the circuit. then to identify function, connect a 12 volt light between the +12 pin and the ground pin. the light should illuminate with your AC controls. this sounds like you misread your AC relay, and this will identify that error 100%, OR you have corroded connections on the pins directly, pulling the connector off the clutch will make this painfully obvious. any good electrical connector cleaner will work along with a tooth brush to clean this

Dodge 1500 1995 pickup 7.5 volts to fuel pumpwill not start applied 12 volts pump runs book sayes pcm de-energize booth relayes and will not send proper voltage to fuel pump

There is a red and white wire feeding the fuel pump relay from a 30 amp fuse. Both the shutdown relay and the fuel pump relay are grounded by the PCM, so if the fuel pump relay is grounded it should be "on" and providing a direct link from the pump to that fuse.
You should have battery voltage on that 30 amp wire before the relay and then on the dark green and black wire going to the pump.
If you don't have battery voltage coming from the 30 amp fuse, the problem could be before the fuse.
That 30 amp fuse is hot all the time, so it is powered by a fuseable link coming off the battery.

Ac problem

Static pressure(Non operating) usually is around 70 lbs and should be even on both sides. Sounds like the systen is too low for the computer to allow operation. I suspect a small leak somewhere. Adding as little as 1/2 lb should allow operation and leak testing.

Xantrex power inverter 1750

The 14 AWG Positive wire should be connected to one side of a 30 A relay (typical fog lamp relay available at most automotive stores). The relay's other 30 A contact should be connected to the battery positive post via a 10 AWG (up to 6 ft/2 m)
