Yanmar Alarm Panel Problems

[Trumpeter5]

Hello All.
I have recently purchased A Hans Christian 33T with a Yanmar 3QM30FG 30 HP. I have not had the boat in the water long and am still working out the bugs. I was cruising last night low RPM and my belt broke. I maneuvered the boat into a safe direction for maybe 3 minutes and shut her down. I found a new belt and fitted it on. When I started the engine back, all three alarms went off ( Water - Oil - Charge) I shut down and checked the strainer which was half full of muck and cleaned it out. Checked oil and it is fine. Engine was too hot to check water. Ran her for another minute or two to see if alarms would silence but would not. I have good flow out of exhaust. I let engine cool over night and checked cooling water. It was low so I topped it off. I still get all three alarms. Engine seems to run fine. Anyone know what could be wrong or what I need to do?? I'm lost!!! Thanks!!!

Are the 3 alarms the: overheating, oil pressure and alternator?? You can get seawater cooling flow and still be low on freshwater coolant. Perhaps a sensing unit wire came loose during the belt change?? Just some thoughts.

Sorry, I missed your pointing out that it was Oil, Water and Charge. Sound like theres a wire loose somewhere.

THe cooling water was a little low so I topped it off. I"m in the process of checking for loose wires. Possibly a loose ground? Thanks! Still working on it.
