    Odd Behavior of Circuit

    Why not visually inspect for the presence of a diode being connected across the bells electromagnetic coil proper. Without an oscilloscope to be able to observe that coils high voltage back EMF voltage spikes, for only a dollar, would be to go to an ACE . . ."type of " full Service hardware...

    Odd Behavior of Circuit

    The diode install polarity is being correct and an industry " common as dirt " cheeeeeeeeep priced diode that exceeds the needs by 900% is being a 1N4007. Not . . . . . INITIALLY . . . . . even knowing your power supply spec, that sounds adequate. I was wondering if voltage reading was at...

    Sir Richard9025 . . . . . Quick Explanative Interjection. . . . . . ( Referencing to your very last photo ) This should have all referencing needed, being all clustered together within a mini schematic . Will give you full details later tomorrow. in the interim, you see the BLUE RECTANGLE...

    Odd Behavior of Circuit

    Certainly sounds as if you're using a common 12 volt power supply for both of units and that with the heavier current consumption of that one bell, that it is pulling down the power supply voltage and upsetting your initial time relays time out constant. Check your power supply with the hefty...

    Sony stereo MHC-GX470 question

    The VALID part numbers are STK 403-130 and STK 404-130, while the other superfluous /irrelevant numbers are either being run numbers or code dates.

    Initially lift one lead of D303 out of circuit and see if the lamp activates on a STEREO station tune in. Looks like either of your AC180 or EFT373 should sub in as being a lamp driver function . . . if you properly . .and correctly . . identify their proper CBE lead assignments. Lastly, if...

    Need help reducing voltage

    If you are trying to . . . and expecting for a 3VDC being at the other lead of that dropping resistor, that is not going to happen until you connect on that 3 Volt at 3 amp load which would actually compute as needing the use of a 1.8 ohm @ 27 watt power resistor for that level of voltage...

    Can you make my 12v LED light up?

    If you can't find those "generic" parts being shown in post # 9 at your electronics supplier, they shouldn't even be calling themselves a supplier !
