Can rectifier failure on one engine effect both batteries? 1996 efi 250's and batteries aren't charging. From everything I've searched it appears to be rectifier on port engine. The tach is very jumpy and at times the voltmeter pegs to zero leading me to think its the rectifier. If it is, could it be draining both batteries? I ask because the port battery definitely drained too low to even turn over the motor. The starboard drained low also although not as low. My thought tells me since I was running both batteries (one for each motor each with Perko switch) on all that maybe the port was draining while the starboard wa working double time? Going to try and test this afternoon. Thoughts?
