I own a 73 datsun 620.......I'm fairly new to the Datsun game and this past week my Alternator gave out for the 2nd time in 3-4 months got a new one installed it and got the battery charged as well.... i turn the ignition and it tries to start but it doesn't seem like it's getting enough power? yesterday i felt the starter after trying to crank it a few times and it felt warm what can i do?
