62 Valiant 200 / 170 cuin /6 - Odd smell - then dead battery

Couple of questions.
1) what vehicle
2) What style voltage regulator (sort of square with a triangular plug with 2 wires?) or ( rectangular with a spade connector on one end, and a screw connection on the other end?)
3) What alternator ( does it have a large stud, and one spade terminal, or stud and two spade terminals on the back?)
4) How did you bypass the ammeter?
