Sorry guy, sincerely did not mean to be offensive; just thought that the $$ for a VR would be better spent on a voltmeter that you could use for this and down the road. Hope you get it fixed. You probably really don't need to rewire the car, just look into the Mad Electrical site for the discussion and fairly easy upgrades.

I looked at he Crutchfield article; the chassis and block grounds are good; as Redfish says, the battery to starter and starter relay are pretty heavy anyway. But the real regulationn issues in your case lie between the large starter relay connection and on in through the firewall connectors, the ignition switch wiring, and back out to the VR, alternator, and ignition system, as well as from the main alternaotr output back into the firewall connections, the ammeter, and back to the main system.
To tackle the voltage issues, consider this:
1) Examine the bulkhead connections and wires for corrosion and melting in the connector bodies.
2) Do the same at the ignition switch and connections.
3) Clean all of the bulkhead connections and treat with dielectric grease; that will likely do a lot for you.
4) Then read up above on the ammeter bypass
5) Route the alternator output direct to the starter relay's big lug.
This gets to most of the main problem areas except the ignition switch itself and a few other lower probability areas..
