I've installed a new battery, 63 amp. alt., and a new regulator... One mistake I think I made was to mount the regulator directly to the radiator support.. I've recently been made aware of the need for the isolator mounts... I've since added these, but to no avail. Did I blow the regulator and/or the alt.? I'm getting 11.8 volts average at post of the alt., and 11.6 at the battery... The voltage increases to approx. 12.2 with fast idle, but the battery still slowly dies... All the chargiing wiring has been replaced with new. What did I miss or screw up?
Many thanks, Pete in NE PA

Run a straight 12 volt wire from the battery positive terminal to the "F" terminal on the alternator with the engine running. (Disconnect the 2-wire plug first) If the alternator is OK, it will go into full output. There is an aftermarket electronic regulator assembly that plugs into the back of the alternator and eliminates the regulator. I used to use that one when converting farm tractors to alternator charging from DC generators. Another alternative is to install a later-model internally-regulated alternator. Most of them can be used by simply installing a jumper from the battery terminal to one of the regulator terminals. The other terminal can be used for a "no charge" light if desired, but it's not really necessary.
