[700rpm]

Lubber, I'd suggest starting with the simple and cheap things first. Try a standard type of cutout. Then go from there. I bought a diode but decided the regular cutouts are fine, and have had no troubles in six years with that on my truck. If that doesn't solve it, then take the gen. to a shop and have 'em check it out. That will tell you if it's OK, and it won't cost you much.

If you're like me, we tend to panic and start throwing money at the problem. But I've found that often it's a pretty simple and minor problem, if I just settle down and think about it first. I just went through that drill with an uneven ride. I was sure it was a bent axle. After much anxiety about pulling the rear end and thinking big dollars, it turned out to be a bent wheel. Much easier and cheaper fix.
