Author Topic:   305 battery charging

I spent 3 days over New Years out on my 305. Given that I did not do much motoring once anchored my starboard (house) battery lost voltage. I tried to charge it up by running the generator with the battery charger on. For some reason I could not charge up the battery using the generator. I tried different combinations of the main battery isolater switches without luck. The only way that I was able to charge the battery up was by running the outboards. Am I doing something wrong?

There is a battery charge switch on the a.c. side of your electrical panel. If that switch is "on" and your main electrical switch for the generator is also "on" and your generator is running your two starboard house batteries are supposed to charge. There is a volt meter on the d.c. side of your panel that should read 12 volts plus if your batteries are being charged. The charge rate is fairly slow. Running the outboards charges the batteries faster. Your starboard battery switch needs to be on "2".
If things don't work as described, then your 305 needs fixing.

I ran the generator exactly as you said for 4-5hours without any charging of either of the engines. Looks like it needs to be looked at.
