Not only do the PMGR starters work hard and long...they require less amperage from the battery to do it.

The bigger, "High Torque" direct-drive starters would pull 190--200 amps, as much as 225 on certain Big Block engines (Olds 455, for example.) These are "stock" engines, not high-compression monsters.

The PMGR starters pull about 150 amps, more-or-less.

The higher RPM of the electric motor makes for more back-EMF, and there's no electric current going through field coils, because the "field" is now a permanent magnet not an electromagnet. Both factors reduce amperage draw.

My original mini-starter lasted for a long time. 280K miles maybe? I kept it, but still haven't gotten it to the rebuild shop. The solenoid is what really caused my starting issues, I think..... when I took that apart the contacts were all but gone.

I replaced my OE direct-drive starter with a Denso 281-8002 gear-reduction style starter earlier this year and am very satisfied. It's spec'd by Denso for "industrial" use, which I assume is for Kohler, Generac, and Cat natural gas versions of the SBC. The Denso unit is, surprisingly, made in the US. The same can't be said of the new production ACDelco or Remy units. I wanted a quality, non-reman starter that wasn't Chinesium. Down sides are the price point ( you get what you pay for here) and the lack of a heat shield. I used a DEI starter blanket and have had zero problems with heat soak. The mounting pad thickness is identical the DD starter, so no bolts were necessary.

That said, please do all pertinent troubleshooting before condemning the starter.
