    Yes, the action is much better understood now that we saw the whole post.
    But as a matter of fact maybe that should be edited out now then, since it's circumventing the TOS

      The control portion of inverter boards is what I always have trouble with.

      I have replaced very few transformers or mosfets.

      I have never spent much time repairing the inverter board because I could always fine one cheap.

        Power Inverter Replacement Circuit Board Question?
        by jdbird613
        So my Ampeak 2000 watt power inverter will receive power from a 12 volt source, and also has a display screen that displays how many volts the inverter is currently using...However, the plug outputs are not producing any power outward...The display screen on the inverter also shows how many volts an item that is plugged in is currently using...Which stays at 0 and no items will power on...I opened the inverter casing and discovered there is some charring and burned areas on one end of the circuit board...What I am trying to figure out is if I can purchase/obtain a new board exactly like the board...

        Fixing the Charge Circuit of the Batteries of the DC Motor
        by Astonished
        Hi friends of electronics

        What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.

        The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.

        Please help me fix this circuit.

        Vizio E55-E1 bad backlights or bad inverter?
        by x_orange90_x
        I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

        I don't know how exactly to test the inverter itself. Is it...

        Short Circuit tester
        by Tarot Superstars
        Hello.
        I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
        The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.

        My multimeter isn't normally sensitive to very small resistance, but when I put a 1 mega ohm resistor...
