I agree, but the resistor only has to reduce the amount that the clock needs, to operate, there will be no more current flowing than what the clock uses In a message dated 1/31/2009 12:17:28 P.M.

For example building the circuit to run the gauges needs a heat sink for the resistor going from12v to 5v and it runs Hot. The bottom line, resistance = heat. I would almost guess the extra heat generated dropping to1.5v would cause damage to the dash if the heat sink was mounted on it. With that big of drop you might look at mounting the heat sink to the fire wall or something not affected by heat under the dash. Just my II.

But I couldn't quite get him to give me a straight answer. So I looked around a little in some of my old stuff and found a slide type Ohm's Law calculator. It will give me the value of the resistor if I know the voltage (12) and how many milliamperes the clock will draw. So, would you then multiply the value it gives you for the resistor x's 8 as discussed in the previous post? I don't know. Probably just easier to grab a handful of resistors and a voltmeter and experiment a little. If you used a higher wattage resistor it might take care of the heat issue. A heat sink would probably make everything last longer. Paul L.
