S.L.O.W. problem

The system check is in the tach and the 4 lights come on briefly and the alarm beeps briefly when I start the motor so they appear to be working. However, none of the lights go on when the S.L.O.W. kicks in. I was wondering about the power pack. I hope that is not the problem as I replaced that at the end of last season for another issue I had.

I am not positive that it is the S.L.O.W. system because the manual describes the condition as "gradually" slowing to 2500 rpm. For me it is very reproducible but does not gradually slow but rather once I try to go over 2500 rpm, it won't let me. I also see a reference in my manual where it says "if the engine goes into SLOW without an operator warning signal, check the engine harness blocking diode" so I guess I will try that. If this is something cheap maybe I should just replace it??
