Scotty - I assume my old alt is internally regulated, as I have never seen an external one. Is your new one set up for an external regulator
I will likely go with an external reg, as everything I have read says they are more efficient and better for the batteries.
no the internal vrs external is a hitachi thing, around 1980 hitachi moved over to internal mostly , but they still made some external. so if you want to go external that should be easy. a datsan ( nissan
) truck from 79 and 80 uses an external regulated hitachi alt ( 35 amp and it costs 60 bucks and bolts right in), just beware that the plug
looks the same but the pins are different. i am sure if you wanted you could find a 55 amp hitachi at you local car parts
place ( or have them order it ) and it should cost around 60 to 70 bucks that uses an external reg. you might have to replace it every 5 years due to corrosion
but at 60 bucks or so....
disclaimer putting a car alt on a boat that is not spark protected might be a problem but on a diesel
it should be okay. also all info i have is from internet
and auto parts store research
, honestly about 3 hours in auto stores.
note the reason for the 3 hours is i am cheap
and when i heard 60 bucks vrs 150 i had to explore the options
