    Can I get this scale to work again?

    Usual failure points are aroud the ribbon cable and connection between the LCD itself and the circuit board. Remove the display and show us how the LCD glass is attached to the PCB - quite often it is via the use of 'zebra connectors' that suffer corrosion and/or simple dirt/grease...

    electrostatic actuators

    I'm guessing the force this type of 'actuator' can assert is measured in micro- or milli- grams? In which case it's pretty much useless for doing anything practical.

    NEWBIE - Seeking a switch for 7 color LED outdoor spotlight

    You need to make a BINARY selection of RGB to get the full spectrum (8 colours) from the display. There aren't many such 'large' binary switching devices available (I can't find ANY in a quick search) as they are mainly 'screwdriver slot' versions that might struggle to handle the current you...

    So you basically want a light 'with an on-off switch' then?

    Replacement LCD needed

    Well, in this case, unless the OEM doesn't come up with the gods then you're 'stuffed' (polite technical response - the correct response is somewhat more rude!). Best chance would be to seek a second hand version on the auction sites. Versions I've seen on eBay are around $150.

    Replacement LCD needed

    What form does the display actually take? Is it dot-matrix? Segmented? or some other symbols we can't guess at? What is the actual machine it came from? What does/did it do? The above details are important as there are certain assumptions we can take from the information - if we had it......

    Project Retro fit

    Making the decision to either motorise the whole process or give access to a manual process has to be made first! What you want to do is perfectly achievable but needs your own decision-making process to be confirmed before we can take this further. The electronics to accept credit and enable...

    Injector driver

    That makes no sense to me - what are you trying to say? Check the 'somethere else' for a short then. I've gone as far as I can with this issue. You would be better off finding someone locally who is competent with dealing with engine wiring issues as we seem to be unable to 'meet minds' on...

    Injector driver

    I can't follow your description - all you need do is connect the injectors according to how they SHOULD be (as per the schematic and pins 16 and 17) along with a common ground. Cylinders 1,3 and 5 connect to pin 16 Cylinders 2,4 and 6 connect to pin 17 Each injector has two wires - one of...

    Injector driver

    According to your schematic, ODD numbered injectors should all connect to pin 16 and EVEN numbered to pin 17. Regardless of what your wiring currently is, just make sure that pins 16 and 17 connect to the right set of injectors. You should measure a short between injectors 1,3 and 5 (then...

    The common junction of V1 and V2 needs to be connected to 0V(ground) reference.

    Injector driver

    The shield ultimately connects to the vehicle ground so you should be able to measure a short from any point on the shield itself (and on pin 3 of the connector) to ground.

    Heater Repair

    The 'wire-ended' thingy is a thermal fuse. If it's blown (measure across it - if not showing a short circuit then it's blown) - there's little you can do. Replacement fuses are available but you'd have to rivet it in place to achieve the protection it's meant to offer. It would be...

    I don't think the sensor is polarity conscious - it can be connected either way around and should make no difference. The shield connections is, however, VERY important.

    Injector driver

    There is no 5V at pin 8 if the actual schematic (not that 'abbreviated') diagram shows. The abbreviated (wiring) schematic infers the internal arrangement after the signal conditioning circuit (R560 to R566 and the diodes D560 and D561). This conditioning circuit is 'classical' for rectifying...

    Injector driver

    Where? I must have missed that. The sensor you're talking about connects to pins 8 and 31 doesn't it? There's no indication of a 5V supply there. D561 would block any 5V from reaching the sensor anyway. 'Vehicle Speed Input' (just above) has a 5V source...... nothing to do with the cylinder...

    Injector driver

    The output from the sensor itself will be minuscule - most test meters wouldn't even register a signal at all and certainly a person unfamiliar with what they were expecting/looking at would have no idea if it was right or wrong. It could be shown, very positively, using an oscilloscope - not...
