Volvo RWD 200 Forum

Replaced my big useless clock with a tach which works great. Hooked up a supposedly functional small clock (which came with the harness) exactly as I have read 800 times on this board that it should be hooked up. It doesn't work. I looked around hoping for something simple like "you need a new such and such", or "crimp the such and such to the such and such". COuldn't find such dumbed down instructions. Instead I read that 75% of pulled clocks don't really work. I also read something about how 12 volts should be going to the clock from the harness and whether or not the tach is failing to accomplish this. Uh....what? I'm a novice at this stuff...can someone explain how I can tell that without frying my dash? I also read perhaps it could be capacitors (what are they, how many are there, what do they do???) that need to be replaced. Then, just before my brain started to short circuit, I read something about pullout caps, microfarads, and decouplers in ECUS. Oh yea, and is it "grounded". I understand the concept of grounding, but how do I know if my clock is grounded. No idea whatsoever. I'm a ninny. I just want my clock to work. Can someone tell me what to do to accomplish the above things, whatever it may involve? I refuse to pay anyone to work on the dash of this car as I'm spending enough on other more serious work. I know I definitely need the bezel and the three rubber feet for the clock. Can anyone help me, in layperson's terms, fix my clock? I've also been trying to find a picture of a back of a properly wired clock to see if perhaps there's a little piece broken off where the green wire attaches. It looks like it should be a double prong. Ughhh. :(
