My voltage drops a good bit around upper 5800 rpms, I notice it the most in 3rd at the end of a run. Is there something that cuts the alternator off at full throttle or do I just need to look at swapping Alternators? Maybe something that cuts it off in the HP tables I'm overlooking???
The alternator pulley has really good belt wrap, so I don't believe it's slipping...
I also notice my A/F normally leans up a half point at the same time, so I'm thinking it's related. I just installed a fuel pressure sensor to see if the fuel pressure drops also.
