    Wall Wart voltages.

    Yes, another idiotic inception.... I would rather be interested in some means by which I could drive a significant amount of devices using a single plug, but, nature does not draw in straight lines. So, when one is to replace a wall wart, and the box full of them does not contain the correct...

    Blind DVD Recorder or Special Remote?

    At the close of C-Band satellite TV signals, I was really deep into those universal remotes for dish... I had one that ran nearly every device in my toad pad. Anyway, there were codes for nearly all devices. So my home studio has grown as a recourse to losing TV, and I found a cheap Sony DVD...

    Beer fridge... Redux

    So, when everything works except the main system, and suggested fixes are to replace entire units or devices, first check the fuses. But, if the main system was tested and was working when other unimportant systems weren't working, maybe the device isn't working properly. I purchased a small...

    Hp power use

    Is a higher horse power motor more demanding for power, than a small horse power motor, or is the application important for a toss up ? Reason is I have a shallow well that had a 1/2 hp motor, but I put a 3/4hp in because I added four gardens that requires irrigation. The new pump is doing...

    Is a circuit necessary in this condition?

    I have an American DJ Topaz 250 disco light that uses a special 250W 24v projector bulb that burns out after a few hours of use readily. I think the burn out is because the bulb is getting hot, but that is the nature of high power projection bulbs. The case of the topaz is small, and the bulb...

    Simple power struggle...

    My furnace is on the fritz. Blower will not quit. I put one of those digital programmable thermostats on and it worked great for about 6 months. I found a fuse that was extremely corroded inside, replaced it and the breaker started blowing. Put in a new larger breaker, ( the furnace is rated...

    The 220v thermostat on my wall heater is obsolete, and I am having problems finding a replacement. I have maybe 5 of these heaters, and they all need the thermostat. Can you help me to diagnose and test these? I checked the resistance, tested the motor, the heating element still has...

    buggy board, bad tech and strange readout... heh heh

    I would be probably better off just buying a new PBA and put it in the fridge, but I feel so close to fixing it!!! Everything still looks good, in fact the readout seems to be running better than it did before except that the sensors are not proper, and read out -8 degrees while the Wi-Fi tells...

    Bonehead connected to the electronics forum

    Assuming your repair has 4 terminals for a two blade ac cable from 110v-120v wall plate.. ac1 ac2 ac3 and ac4. It has further two cable's with a switch in it. The slang being "always switch the line not the load" I have to think that the load is the terminal that has the switch in the cable...
