I'd appreciate advice on whether the following assortment of problems is likely due to one common cause, or whether they are simply a number of unrelated non-working devices. I have a '72 tii, and the following do not work (and have not worked since I bought the car a few months ago): the horn, the cigarette lighter, the tachometer, the dashboard light, and the interior light. The headlights, emergency flashers, speedometer, turn signals, etc., all do work. I should also note that the temperature gauge fluctuates, and seems to indicate a higher temperature (incorrectly, I believe), when the motor is running at higher rpm's. Any insights (including guesses) as to what my problem or assortment of problems is/are would be most welcome. Thanks.
