This is for my '48 GMC that had already been converted before I got it and is also using negative ground. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Feb 2013 Posts: 250 'Bolter | | 'Bolter Joined: Feb 2013 Posts: 250 | Thank you Tim! Just what I needed. | | | | | Joined: Feb 2013 Posts: 250 'Bolter | | 'Bolter Joined: Feb 2013 Posts: 250 | ....Tim, just what I needed but electrically challenged as I am I need a little more information. The diagram you provided shows one direct connection from the Positive + battery post to the starter and another direct connection to the ammeter. Does the second connection have to be run separately or can it run from the starter to the ammeter? Thanks in advance!

12v negative ground.
You can run a big "+ power lead" cable to the starter post, and the heavy wire from starter post to the ammeter.
Some people have taken the guts out of the voltage regulator, and then run the heavy-wire from the starter to a post on the voltage regulator box, and the heavy-wire from the voltage regulator box to the ammeter. That is the "neat-looking solution", using original wires..
Before I read that idea, I use a bolt/nut connection near the old voltage regulator and carefully/thoroughly wrapped it with electrical tape.

It's funny but the previous owner went to a lot of effort to modernize the electrical system while I'm trying to do just the opposite. | | | | | Joined: Mar 2010 Posts: 10,275 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,275 | I use the gutted voltage regulator trick as well. Nice tip I learned in here a while back. Maybe from Tim.
