    Tricking Solar inverter

    A grid connected system is exactly what it says. There is NO inbetween where you can start fiddling with the system willy nilly. Reasons why NO running of the inverter on a grid when the grid is down has already been covered above. If you want a system completely isolated from the grid, you...

    Old module does not work

    Obviously not everything as it is still faulty. Given you have one component, either a left or right side ( not certain as now you are talking doors) it should not be too difficult to trace back the fault given there would be 2 identical power section circuits, one of which works. Control...

    help ID IC used for dusk/dawn controller

    Manufacturers would buy these items for 10 a penny (or more or less). Pic chip has many added advantages so no, not an overkill.

    Help me fix my Santa

    A small cheap tactile switch would suit. Available at any electronics shop or online 10 for $1.00 so to speak...cheap as. Any momentry contact switch would do........

    Old module does not work

    Well, that's all about as clear as mud...... o_O As I said earlier, the tab is connected to the track purely as a heatsink, there is no other connection to the track. Possible the device which has been subjected to the extreme heat due to the lack of physical connection to the track, is...

    Malfunctioning Popcorn Machine (burning resistor issue)

    Suggest you do a Google on how to test a zener diode with battery. The low reading on diode test on the meter, zener appears as though it is faulty. Capacitor will be mains rated, possibly X2, could have that voltage BUT not the way to test it. Lift one leg and test with a capacitor meter...

    Problem with finding power switch microcircuit

    Photo shows nothing in relation to your query.

    PWM hall effect throttle problem

    Another option is to use say, an ATtiny85 and map the new input to your required output level.

    Sharp RT-3388a solenoid/plunger not working

    As I said previously, don't go sticking ground shorts or any shorts unless you know what you are doing. It will likely cause more damage.

    Perhaps a link to what you saw and where......... ??? :rolleyes:

    Sharp RT-3388a solenoid/plunger not working

    Don't short base to collector.

    Malfunctioning Popcorn Machine (burning resistor issue)

    Red Blk Blk looks like 20R to me.....OR brown blk Blk..... 10R. Either way, it's a fusible resistor intended to protect the circuit. If it's burning there will be some kind of short or excess power draw. Looks like a fairly crude power supply, non-isolating.

    Heated jacket temperature regulator

    No, pwm simply means the power to the load is switched on and off at a high rate with a variable on off duty cycle. Nothing to do with any high initial draw or capacitors. The resultant power output if say 50% on and 50% off is 50% speed/ or light output or heat or whatever, BUT with power...

    Sharp RT-3388a solenoid/plunger not working

    ok....if you have a link to say a pdf file for the circuit diagram, that would be ok also.

    Mobility scooter

    Wow...expensive tinkering........ Upgrading the controller probably make no difference as you want more power. Perhaps larger motor and battery required as well. Start up that route and cheaper to buy the whole 425 model.

    Old module does not work

    W Well, it does connect to the tab of the transistor which is usually the collector of the transistor, same as the centre pin of the 3 pins, (depending on type model etc) ..............BUT that track is not connected to anything else aside from the transistor tab. So in this instance the track...

    Sharp RT-3388a solenoid/plunger not working

    You WILL need to post a higher resolution photo of your entire circuit. It is currently unreadable for detail. Kellys_eye was referring to grounding the "TOP END" of R821 or R823, which are two 10K base resistors on the transistor number Q803. Be careful grounding willy-nilly as you can damage...
