Resistor and Capacitor ID

RLM431
RLM431 10 months ago

Hello

New to the site. I’m no engineer and not an avid electronics enthusiast but I tinker with things. I can research and typically find an answer but I’m having a little difficulty with 2 capacitors and 1 resistor. They’re from an old marine tachometer I’m trying to bring back to life. I’m looking for some help identifying them and suitable replacements. I have attached a couple of pictures.

Any help is very much appreciated.

    For Picture 1, you'd be better off searching for a schematic for that tach.  It's fried beyond recognition for me.

    Kmikemoo, I’m trying to reply on my phone so not sure how to tag you but, thank you! Yeah, that resistor is toasted, I can identify the last 3 bands but not the first. I’ve been scouring the www for a schematic but nothing comes up for the darn thing. If I had found oIt’s a 70’s omc accessories 2 wire tach, just signal input and ground. It was made by gale products and model # is 121614. If I do find one it will be a lot easier.

     anniel747 I vaguely remember some odd notation in older service manuals, but on the vintage radio equipment and OLD Basler voltage regulators that I've worked on, they're all rated in microfarads - MFD.  It's probably because there wasn't an ASCII symbol for mu, µ, back then.
