				voltage regulator how do you know
			 
			
			Hi All, 
		
	
		
	
			
				How do you know what alternator you have so that you can buy the right voltage regulator. I have a 72 T 2.4. I think I have a 55 amp alternator which should make it a motorola, I think. I need to purchase a voltage regulator. The one I have is a black plastic covered version. I think I need to buy a bosch regulatory but need feed back to know. Any thoughts to make sure I purchase the right one.

 You need the Bosch (mechanical) regulator to match the OEM alternator. This sits on the left side panel in the engine compartment.

					I probably will need a rebuild of the alternator as well so I thought of replacing both alterntor and regulatory at the same time. I wanted to keep this combination. I've read on Pelican that it is better to stay with separate regulatory/alternator combination rather than going to the more modern self contained regulatory in alternator combination.
