Review on 💡 Powermaster 48237 High-Amp Alternator: Optimize Your Power Output by Andrew Cramer

Installation documentation states that you must install additional grounding, but does not provide an easily accessible ground point or instructions. This is not usually a problem since you are simply grounding the generator chassis, but trying to use the bolts holding the block together as a ground will cause a problem. The screw heads are uniquely designed and cannot be removed unless unscrewed (and possibly removed). I also suspect that doing this will void your warranty since you're basically taking the device apart to make a ground connection. I ended up drilling a small hole in the backplate and attaching the ground wire to it with a screw. Performance is great, fit is perfect, just needs a good grounding point.
