Okay, "Micky Mouse" has been there.
First; Test generator, then install & wire it up normally, making sure the field wire is NOT grounded. Also, make sure the Arm/Fld wires arn't interchanged on Gen/Reg. The field wire is the smaller of the two. You could run a ground wire from the Gen. to the Reg. too.
Second; Remove the cover from the regulator & inspect. You may find the 'cut out' relay welded/ burned up. If so replace the Reg.
Third; Install a new regulator & polarize it acording to the instructions inside box/Motors Manual.
Forth; When starting make sure voltage is set 13.6-14.2. Coil will/should have 'ballest' resistor that drops to 6.8-7.2 when in run position (12V to start).
Dash guages may be toasted but easy to get/replace.
Good luck, JM......
