Ajacks81

Ok, sorry for taking so long. Ok well I'm an idiot. I didn't have the belt tight enough. But, when I tightened up the belt it caused the water pump bearings to go out. Well It's all replaced and works great if you like your volts up in the 15 range. Now I'm down to fixing the short in the rear harness and the temp sensor. I bought the VR from eBay from vintage imports. It is a NOS from 1980. The Alternator is from an early 280z if I'm not mistaken. Thanks guys for the input.

Ok I will see what I can do. Thanks guys

I just joined this forum with my 74 620, I was searching around and I have same issue. New Alt, Bat, VR and just rewired all to factory diagram. No charging above 12.2 at all. Upgraded the Alt to 60a Ext reg. alt. Solid state VR with no adjustment. Now I am puzzled. 12.2 w/o lights 11.8 w/lights 11.5 w/ everything on Rev up changes Disconnect battery and vehicle still operates Starts right up no problems, but its only a matter of time. Can we continue here or should I create new thread?

It has L20B, A87 head ported and polished and decked. Pathfinder Brake upgrade with a 81 zx brake master waiting to go in. Lowered a lot (I do not know how far as I bought it this way.) Upgraded to 60a Alternator, points are gone and well I think that's it. Here are some pix. This is my first forum ever, be patient if my photos do not show first go around as I am still learning.
