Re: new battery & alt. = 11.40 volts?
Make sure the VR chassis has very little resistance to the alt case, less than 1 ohm. I believe the VR chassis is bolted directly to the radiator support, no wellnuts as with earlier years and no ground strap on one mounting bolt.
Next, VR F wire should go to the right terminal on the rear alt connector, blue wire?
VR #2, orange wire turns to white wire on left terminal of alt rear connector, confirm.
VR #3, is a red wire connected to, eventually, to horn relay buss bar with other red wires, one from battery junction block.
VR #4, is pink wire from firewall connector and other side of firewall is brown wire to inst cluster.
On alt connector, blue wire is field voltage, no field, no alt worky.
Should also have battery voltage on white wire to turn off GEN light with alt running.
Once wiring is checked out and alt is outputing, you will have to readjust VR to lower voltage. At VR temp of 130°F, battery charge voltage should read about/around 13.8 volts, no accessories on, just ignition at 2500 rpm, usually after running 15-20 minutes to heat up battery from the charge process.
All the above only applies to an OE 10DN alternator system, externally reg'd alt. You can swap out the VR with a Duralast/Wells reg'r, P/N VR715, plug & play, and let the charge system do its thing.
Externally charge the new battery.
