Thread: Dumb Wiring Question

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.

First of all not a dumb question, as many of us are dumbfounded by automotive electronics!
Secondly I would use the directions for the new guage, since if anything doesn't work, it will be covered by warrenty. I know only a little about car electronics, but unless it is a pain to wire the way it is stated, I'd just follow the directions. Hope this is helpfull until one of the pro's chimes in!
