Recently had the entire ignition replaced including stator , trigger , key switch , power pack and stator adapter bar. Ran great all night. Coming back into port as soon as I slowed down the voltage dropped to about 8 volts. Before I slowed down it was normal , around 12 to 14. Now , going back before this, we were fishing at night , so I had the anchor light on for about three hours with the engine off. Took the boat back out two days later and all was fine,with normal voltages,no drops. Battery history: It is about three months old. First month I did a lot of cranking due to getting stuck out on the water { thus,why I have replaced the ignition system}.After that , the boat sat in the driveway for two months untouched. I put my vector battery charger on it for test and the charger gave me an "F03" fault code which means either an internal open cell OR the battery is in sulfated condition and needs to run on desulphate mode for 24 hrs. First , can a battery that is only three months old begin to accumulate sulfides after sitting for 60 days?. Second , if the battery was low , could this have been the cause of running normal voltage and having it drop to 8 upon slowing down? Again , I ran her the other day and all seemed fine.
