    Low voltage cut in/cut out

    You could make a comparator circuit fed with a Voltage divider input and a transistor to drive a relay for your fans but why not do it the simple way; Thermal switch to relay to drive fans? If you need to manage noise, why not consider suppression

    Faulty Receiver

    Perhaps its related to the circuitry that displays the on screen menus? Maybe you can fiddle with the font color and see if it changes on the screen. Try selecting opaque to see if it disappears. Btw; I love it when Judge Judy says: "Does it say stupid across my forehead?"

    Help repairing power lift

    Looks like they are only using the normally open portion of the switch in the circuit. In other words, any switch that will close the top two pins circled in yellow (last picture) should work provided it has an adequate current rating.

    Help repairing power lift

    Momentary Spdt like this one but I'm not certain of orientation of pins. Some have common pin on one side as opposed to the center.

    Help repairing power lift

    Only problem is figuring what wire goes where. If you have the broken part of the switch it might lend some clues. Or, if the black bases of the switches have numbers on them, that'd help too. Plan B is to guess at it. I'm guessing the common pin of the switch is the center pin. The two...

    Latching relay for actuator use?

    We haven't seen you circuit to know how to wire it. Choose your latching relay like you would any relay; Start by defining your load so you can determine the contact ratings. Then coil voltage you need and any current limitations you may have (from the circuit your hooking it up to) And...

    What Are These Parts Called- Where Can I Get Them?

    Maybe not. Fiber is not mandatory. If your field wiring terminates in the panel you could retrofit a Plc into it. Btw, They have remote I/O modules that only use one serial com cable. You also potentially have big money recycling the copper you have.

    What Are These Parts Called- Where Can I Get Them?

    Could be, but the fact that black wire is used tells us it's high voltage (usually not controls). Yes, they didn't properly label wires.

    What Are These Parts Called- Where Can I Get Them?

    They are old obsolete terminal strips. You could replace them with similar such as AllanBradley 1492ca47, or retrofit newer style 1492-w3 dinrail mount terminals. Besides the terminals you will need "end Barriers" (insulator) and "end anchors" that keep them from sliding. The relays are old...

    Newbie leds for blinker lights

    They don't like fast food. Lol The auto-canceling works by a plastic spring under the steering wheel that disengages the switch. They get brittle and break sometimes causing blinkers to not turn off when wheel returns to its center position. If this is the case you can probably find a...

    Relay & switch wiring

    Your load should only be 8.5amps. If you were really overloading the circuit you'd be blowing fuses. Perhaps there is something wrong with the type of switch or the install? Another work around could be to use low current leds instead of ge1157 lamps.

    Another idea is to use small vibration motors in your seat. You could put one on the left side and one on the right?

    Relay switch help

    Yes, maximum ratings of the relay contacts. The coil is 5v but the contacts can be from 0 to 220v. Think of it as a light switch.

    Relay switch help

    That's the contact ratings. A load of 12v is less than 220v so your fine provided you don't exceed 15 amps. No minimum.

    Help stereo Light indicator problem on a 1976 technic SA - 5360 stereo receiver:

    Also make sure you have an external antenna hooked up. Even a cheap dipole wire antenna will do. By the way, nice receiver. They sure made quality stuff back in the day.

    PLEASE HELP! Racing light bar

    Congrats on your recovery. One idea is to buy a electronic turn signal flasher and modify the resistor (provided it has discreet components) so it flashes quicker.

    What does your workshop / workbench look like?

    @(*steve*) So wouldn't you just be using your best scope 99% of the time while the others collect dust? I'm sure equipment can become like an old friend that you don't want to part with, but I expect most sell off their old stuff so they can get the latest and greatest their budget allows...
