Ok two weeks ago I replaced my port batteries and while hooking them up I dropped a long wrench and it fell between the positive and negative posts. And yes it was a scary event. The wrench contacted both posts and put out some major sparks and actually pitted the wrench where it got hot. So I continued to install the batteries and all appeared to be ok. I had no problem starting the port engine and when I went for a short cruise the batteries where charging close to 14 volts and then dropped down to about 13.5. So this past weekend , my next project was to put in a new smart charger. I turned off all power and all battery switches but made a stupid error and did not disconnect the battery posts. So when removing the old charger the # 3 bank positive hit the ground for just a second and sparked a little. I continued the install and started up the new charger ( pronautic 40 AMP) . It came right on and ran the self test and everything was great. Should correct charging and no faults. Took the boat out and all was good but the port engine / battery charged looked a little high , 14amp the whole time I ran it. I then went below and checked the volts on the panel meter ( fist time I ever used it) and the port side shows under 12 volts and stb. is 14. This is how it reads regardless of charging by shore power or alt. So my question is this - did I destroy the battery two weeks ago or did I damage the isolator diodes or something else. I am going back up this weekend to check the battery and the charger with my volt meter. Also as info I found no breaker tripped in the bilge, battery switch panel, under the helm or main panel in cabin. I could not locate any other breakers but there probably are more.
Also one last note. The new charger will go thru the standard charging sequence and then go to the standby - ready mode as if all is good fully charged which it may be - wont know until I get the volt meter and battery tester on it.
