Location: Eau Claire, WI | Just a thought on the alternator/loop chargers.
I've been told that the newer computer controlled direct inject motors, Optimax is the one I was told about, are dependant on recieving the proper amount of volts to operate properly. I was told by a Merc. technician that they need at least 13.2 or 13.4 can't remember which, or they can start to run rough, improperly, etc. Which based on the way I saw a guys 225 behave when his starting battery went bad and he was down to 12 volts or less, I suspect this information to be correct.
That being said, I'm wondering if a stock alternator has enough output to charge partially drained trolling batteries and allow enough to get to the motor to operate properly? Maybe these systems compensate for that?
Typically on your volt meter you should read 14.2 - 14.4 if your regulators and alternators are operationg properly. Take some of that away to keep more than the starting battery charged and then what?
I don't have the answers but these thoughts crossed my mind when reading this post.
Also, remember that not all motors are running alternators, some are running stators under the flywheel, similar but not a true alternator. I understand the 4 strokes have pretty decent size alternators but most 2 strokes including the direct-inject units are running just enough to keep the motor running decent and to keep the starting battery reasonably charged.
Might be why some of the guys with lots of electronics (the new color units pull a lot more amperage) are using a separate battery just for those?
Just some things to consider and ask about before making a purchase. Sounds like a neat unit if they work as well as advertised. Suspect for the guys that run long distances or troll a lot they might be a neat thing to have. |
