Alternator/regulator upgrade
Hi,
My '67 Dart is showing very little charge voltage, ~12.2V when off, ~12.2V when running and the ammeter sits 3/4 the way toward full charge on the right hand side (~30A ?).
The car starts ok, although it's only used in the daytime in good weather so not much electrical load. I'm wanting to sort this out as it's not ok to always have that high current showing; I'm not seeing the normal high charge after starting that gradually reduces as battery charges.
The car doen't have the voltage regulator on the bulkhead, it's been modded at some time. The alternator is a square back with I'm guessing an aftermarket voltage regulator attached to it, picture here.
The alternator has 2 field terminals, one red wire from the stud terminal to a field spade and one green wire that may come out of that chrome box. Aftermarket regulator?
I'm needing suggestions on what route to take please.
How would you deal with this set-up?
I haven't yet but I will check the voltage at the terminal with the green wire (field excitation?). I suppose that either the alt or reg could be bad.
Would you keep this set-up and replace whatever is needed with the same parts?
Is there a preferred make and model of aftermarket voltage regulator to attach to the alternator?
Reinstate the original regulator type?
To replace this 2 spade terminal alternator, I would buy a later 73-74 Dart item?
