The boat is an 86 268 with a 5.7 omc. After I changed the alternator the other day I was testing charging voltage. The battery was steady at 15.5 volts. The alternator is a 3 wire type. I checked the voltage at the sense wire and it was 14.5 volts, so the internal voltage regulator was doing what it was suposed to do. I started checking voltage through the circut and by the time the wire goes up to the key and comes back to the alternator I am loosing one volt. In searching on the internet and speaking with several people I figured out that running the sense wire to the bat wire on the alternator would give the alternator a better Idea of the state of charge of the battery it was servicing. Which it did. As soon as I made the change the voltage at the battery and alternator was at 14.5, this solves any over charging problem. The voltage up at the switch was 13.5 so I am still loosing one volt through wiring, ignition switch, connectors, etc. So my question is, is this a big deal:huh:. I'm ok with it. But I'm not a boat electrician, just some guy with a meter. Do any of you guys out there have any thoughts on this?
Any input would be apreciated. Thanks in advance
