My "replacing the gauges project" turned into more than I thought it would. Once I got under the dash, too many years and two other owners required a lot more re-wiring to clean up some ugly stuff. The car originally had an ammeter and I will be using a voltmeter so the #10 wire from the alternator (GM single wire) comes into the cab.

The question is, does the wire from the alternator have to go directly to the starter solenoid/battery post first or can it pick up the circuit at the fuse panel? I have wired a couple of houses and even built a stereo amplifier and so to me a circuit is a circuit. Why would you have to go to the solenoid first or do you?. Line resistance? Etiquette?

Thanks for your comments, I have always learned a lot from you guys.
