Mechman sent me a smaller pulley to get the RPM out of it at idle. But it also started giving me problems right before I traded the truck in.

[quote name='A_Contraptions']do remember, overdrive = smaller diameter pulley. under drive = bigger[/QUOTE]

Sorry, overdrive on both alts and am also looking for an overdrive crank pulley

[quote name='undone1']In reference to alt..yes....to the crank..no...[/QUOTE]

Yeah, correct. I made a mistake in the OP

[quote name='A_Contraptions']just making sure. I wouldn't change the crank myself. the alt company is supposed to use your engines stock crank diameter as a general reference to the pulley for the alt. atleast a lot do to avoid over spin and destroying bearings.[/QUOTE]

Alt was originally made for my car, which idled at 1500. It doesn't have enough output at 500 rpm for what I'm looking for. I don't know if I'll have to send it in and get something replaced or what.
@mylows10; was going to contact Mike and see what the issue is
