    Sunbeam Electric Bedspread stopped heating. Anyone know what the element resistance should be?

    Utter rubbish....you can get within the ball park which is what you are trying to do. eg...220v/2200R=0.1A = 22watts per element.(seems about right) Or if 120v supply....(op does not really say....just that they applied 120v) 120/2200R = 54mA per element or 6.5 watts per element Should be a...

    APEX JR. subwoofer amp blowing fuses, bad caps found

    It's glue. Chances are the semi's will need to be removed to test successfully also. You will need to read the marking to determine just what type of component it is and find the specs on Google search. What does the bridge test..???

    Sunbeam Electric Bedspread stopped heating. Anyone know what the element resistance should be?

    ohms law should give an indication.........then relate to the wattage. #2 sums it up though.

    APEX JR. subwoofer amp blowing fuses, bad caps found

    Black stuff is glue. Cannot see any "aluminium bare spots"........... :confused: With power off and disconnected, best discharge the caps with a suitable resistor, then remove and test caps with a cap tester/esr meter. Running the unit without these caps in place could well do more damage than...

    What's 'fast enough'?

    These so-called fantastic speeds are normally applicable only in captial cities or in very new development areas. As noted, downloading a movie in 3 seconds as one polly quoted a couple of years ago with reference to the NBN. I roughed it out to 3 days here and we are not what you would call a...

    DC boost convertor

    Aside from that, could present problems being "constant" as the panel output changes to lower than anticipated. Best add a battery to the output first.

    Voltage calculations in Fixed Format

    Don't know about all your equations but a quick work out in my head shows if 5v on the Vout, Vin would be 67.5v.

    Help Identifying this electronic component ?

    As noted, more likely to be in the wider shot. I'd tend to go for the marking just to the right side of your photo.

    why are theese cables connected to my ebike battery

    Likely individual cell connections to monitor charge balance. Unlikely you can "fix" anything as these would be required and the battery would be sealed.

    Is this the sign that my Inverter Battery needs replacement?

    These two statements contradict each other. If you suspect the battery, take it to a repairer and get it tested.

    Reversing AC motor

    Looks like sprayed ...doesn't get into the slots...better to use insulating varnish and heat the whole lot before and after....no idea what you mean about "rewired the stator too"....that IS the stator.

    Reversing AC motor

    Looks good....now did you revarnish the windings or just make the outside look pretty...?? 1948 motor, windings would be pretty flaky on the insulation side.
