| The gasoline PM has either a 180A((Lester 11792)) or an optional 220A Denso-type alternator((Lester 11793)); they are traditional "fixed voltage" and not of the modern "smart" variety. [[https://www.promasterforum.com/threads/alternator-amps.93526/post-737110|This VIN decoder]] will indicate which alternator a van was built with. In either case the six-groove pulley ratio is 2.84:1.((https://www.promasterforum.com/threads/alternator-specs-for-gas-pms.99215/post-794345)) Output when cold is ~14.3v; voltage may be regulated down to ~13.8v when hot. | The gasoline PM has either a 180A((Lester 11792)) or an optional 220A Denso-type alternator((Lester 11793)); they are traditional "fixed voltage" and not of the modern "smart" variety.
