My water temp and charging alarms are going off after running an hour or so with a Yanmar 20qm20h engine sea water cooling. I know the alt is charging and the engine is circulating water and it doesn't feel real hot comeing from exaust, nor does the block feel to hot. I did an ohm read on the water temp sensor and with engine off will read ground on wire running to sensor termanal.
I'm lost at what I should be looking for. Any help and suggestions will be appreciated.
