Gravely 272 Z Kaw Watercooled Model 992074 Ser# 102 Started getting "Power Fault" error last summer occasionaly. If I went ahead an started eng, let it run a few minutes, then shutoff an restart it would go away. Also, Eye-Q would show charging voltage 8.4 at first, would slowly climb to 14.8. I might add I questioned dealer when I first bought it about the voltage being 14.8, he said that was normal, but that's what it showed from day one. Anyway, last week when I first started it for the yr it started doing it again, so I went an bought a new battery. Did same thing with new battery. Now for the weird part, I don't normally wash the engine, it stays pretty clean, but sense I had spilled some acid while replacing the battery I drove it out in the yard an gave it a good bath. Was letting it run at idle, voltage was showing 8.4, blades would not engage, got it wet enough that it died. When I restarted it everything went to working fine? Have tried unplugging all the connectors an cleaning them, nothing seems to have an effect. Any suggestions on where to start looking? Also, does that Eye-Q Comp have anything to do with voltage, or is it just a time tracker? Thanks.
