I have a 1971 240z with a 350 in it. The car runs perfect and I love it, the car pulls faster than batman out of his cave
. Except Iv been having some weird issues with my charging system.Im running the Delco 3 wire alternator the 63amp. And here is how I have it hooked up.
Of course the bat wire goes straight to the battery terminal post, the red wire on the plug labeled F#2(Field), and it goes into my post on the starter, I know I could just run a jumper wire from the Bat post to that terminal.
The white wire is connected to the post labeled R(#1), and I have it connected with a 3amp diode to a 12v source that doesn't go on until my ignition key is turned on, and the diode is there so I don't get feedback and I can turn my car off with the key again hehe.
The problem I have is or Im not even sure that its a problem. Is it seems to me as if the alternator switches on randomly when ever it wants, It definitly turns on when the car goes on, but sometimes when I do night driving my lights dim, and it does seem as if Im running off the battery. At first I thought my connector was loose, so I made sure thats nice and snug. Now on the other hand It might just be me not knowing and lacking knowledge on how a GM alternator is suppose to work, since I own 3 Datsun all with KA's and L series engines hehe.
I did have the alternator tested yesterday and it checked out fine. I also have the AMP Meter completely by passed, since I know thats a culprit of all problems since their only 35 amps hehe.
