Just tested my VAC with my Dad's Fluke 73. Was reading about .006v to .010v AC with about 14.24v DC at idle so seem to be good shape there.

Not yet, maybe I can do it tomorrow. Really curious to see what it's at.

Well I unscrwed the 140A alt fuse, and it made no difference so I don't think this is my problem.

Hey guys, new here. I have a built 47RE by Source Auto in Clackamas, OR. I don't have a 4th gear lock/unlock problem, but a surging problem right when it goes into lockup. Did it with old transmission and new built one. It really started happening when I put in DAP 150hp injectors. Basically it will lock up way too early sometimes with OD off into 3rd gear and buck. It does it everytime, and even in 4th. Just wanted to make sure my alt was good. So I guess my question is, where do you measure the VAC, at the alternator or batteries? I just have some cheapy Innova DMM. It has the same symbol that Moparman showed in his video, but has 2 options...200 or 500. I tried measuring at batteries and alternator and even with engine off I get 25.6 VAC. Even when I unplugged the wiring harness at alternator it's the same. Doing something wrong, or do I need to borrow someones Fluke? - - - Updated - - - Think it might be my meter (Innova 3310). I just tested my laptop charger that's supposed to be 19.5v, showed 42v. Just for fun tried AAA 1.5v battery, showed 1.32V DC and almost 2.8v AC?
