I'll try to keep this as short as possible...two weeks ago we went to the boat to spend the WE...on Saturday we were going to get a pump out and to fill up with fuel...the port engine started as usual...the fuel pump for the starboard engine primed as usual but the engine would not turn over....I only got a clicking noise...it had been several years since the batteries were changed so I assumed I needed new batteries...the engine started fine with the emergency start switch activated...we cruised to get the pump out and fuel without issue...I had to use the emergency start switch again at the marina after fueling up...
I replaced all of the batteries a week ago...one group 27 deep cell for the port engine, one group 27 deep cell for the generator, and two group 31 in series for the starboard engine and house bank...I was running short on time so I did not attempt to start the engines that day...
Today I went to the boat for some light maintenance stuff and attempted to start both engines and the genny....the genny started fine as well as the port engine...however I had the same clicking noise and no start from the starboard engine...I double checked the tightness of the battery connections and all terminals are clean...the starboard engine will start and run by using the emergency start switch...I thought maybe I have a bad ground for the 31's in series so I used a jumper cable connected to the neg post on the batteries and the ground stud on the port engine.....this did not help...
One thing I noticed that seemed odd is when I ran the bilge blowers while connected to shore power they ran fine....when I ran the blowers while on battery power they ran but at a reduced power and the green indicator light on the bilge blower switch was flashing...
Any and all input in finding the problem is appreciated...
