It really shouldn't matter. It's just an amprobe.
According to a video posted the other day these rvc are directional, one way will read negative amps and the other positive amps but that was a YouTube video so was just wondering if anyone could compare it to there's I just bought this 05 and no service records or anything so I am just going thru it

I sure doubt that, as it's no different than this....

But I suppose it's possible, as they have ones that will detect 3 phase rotation....

Here's the 06...

Thanks I just wanted to confirm, we just bought it today and while driving it back she noticed the volt meter moving around which is normal but just wanted to check that is on correctly

The airbox lid was loose because the screws were stripped so I cleaned the the intake box all out and the maf had bugs in it and cleaned the throttle body, installed the big case dr44 alternator off of my 2012 on it and put a thicker gauge charging wire, before it was going down to -2 amps now it only goes down to 4.8

Well buddies 408 totally ate the crank. The rods were also magnetized but the shop un-magnetized them and the new eagle crank is balanced and ready to install.

Still going to be awhile before either this 408 or my 370 will be done but I like checking in on them weekly. And I figured carnage pics are always cool.

This is multiple surfaces of the crank not just one. That's how the shop determined low oil pressure was the cause of the failure.

Ouch! Glad the block is alright. I have been looking for an RCSB to build because I don't want to mess with my Tahoe (need to keep one reliable vehicle), but now I am questioning whether I want to punish myself like you have! Haha.
