38, This is very similar to exercise I posted earlier this. High resistance electrical connections along with a loose ground. If you were checking voltages in some of the circuits you may had some crazy readings.
Now I would check that electric PTO current draw to be on the safe side as I have seen them partially shorted and still work. Matter of fact I had a JD737 with one that was drawing 16 amps which why the charge light was coming on at idle. The clutch shouldn't be drawing more 7 amps max with 3-5 amps being the norm.
Also I assume you do know the difference between CA and CCA ratings and hoping you meant CCA as if CA then it is defined too small in my opinion. I usually install no smaller than 230 CCA on most of smaller rider engines. The reserve time is going to be low on that 170 CA battery as it be dropping to about 130 CCA capacity if not lower and won't take long to have the voltage output drop too low.
Also a battery with high internal resistance with can check good voltage wise until loaded.
CA = Cranking Amps at 32F
CCA = Cranking Amps at 0F
