I am breaking in the new motor and noticed a weird issue at higher rpm.
At about 6000rpm I get a harmonic vibration in the dash/car and all my trouble-dash lights come on and my voltage drops to 12.2-12.3v like I turned the key off.
I just installed a new Saturn alternator (96amp) with the new motor. It is wired to the stock wiring with the L wire hooked up to the stock harness and the S wire ran to the battery post, which is also where my fuel pump is wired to. The F wire is not hooked up.
I don't know if the vibration is another issue with the motor but if feels fine otherwise. Could it just be from the stiff poly mounts and no balance shafts?
I have attached a log of the issue, any ideas/suggestions are greatly appreciated.
Thanks!
Travis
