Looking for a little help. I am converting from the gen to an early style 55 amp alt. I say early style since it still uses an external regulator. I am needing help with the wiring for this. Any suggestions???

Hi Dick, Unless you have to use that alternator I would recommend getting one that's internally regulated. Much easier to install too. All you need is a wiring kit from Crazy Lights on E-bay. I think I paid about 28 bucks for the conversion wiring kit. I got a chrome 105 amp alternator in e-bay new for 58 bucks. Well worth the conversion. Generators are unreliable. Jim

gen to alt conversion

I appreciate what you said Fiddlerpin. I am strongly considering the internally regulated alternator that you suggested. I have the other sitting on my bench and was hoping to save a few bucks. There is no doubt that the wiring would be easier with the internally regulated. Cheap is clouding my judgment.

Here is a link for a 10dn externally regulated diagram

You will have to duplicate the alternator to regulator wiring to match the diagram and the main difference is
On terminal #4 on the regulator connect the 20 gauge dark brown wire that was connected to the A terminal on the generator ( at least on a 57) that comes from the gen dash light. If it wont excite ( or you dont wish to use the gen dash light ) add a wire from a switched 12 v source with a 10 ohm 5-10 watt resistor ( can get at radio shack or at least used to ) inline with terminal number 4

Regards, Robert

Dick....I see nothing wrong with using a 3 wire alternator, if you've already got on....If you're anything like me, you've got an adbundance of them laying around the garage.
