Good to know. I did look into modifying the battery tray and fitting a heavier-cranking lead acid, but like everything else on the SF the battery compartment is a tight fit with zero scope for enlargement. Mine's had engine work done as well and runs higher compression than stock. I suspect that's why the sprag is goosed. As plug and play mosfet units are readily available and Skyrich make a drop-in replacement lithium battery it didn't seem worth trying to faff about. Might as welljust bite the bullet, and go lithium at the same time the sprag gets replaced.
