Help please - we have a 416 with a 4154 Perkins Engine and a Balmar 75amp alternator.
Question - is it normal for alternators to only produce 2/3rds their rated output?
What type/model of Delco alternator should I get for a spare? I need at least 90amps true (I am aware of the belt problems). Would a Delco large frame fit? (I am ok with disabling internal regulator)
Can't afford Balmar prices.
