Chart B shows the more stable voltage and current reading on a regulated rectifier. voltage supplied from either the flywheel and the stator or the alternator. How Many Batteries Should I Have On My Boat? with the engine running at approximately 1200-1500 RPM. And depending on what brand and model of engine you are working with. Ok guys I bought a rectifier at Radioshack for $2.00 instead of buying the exact replacement for $60.00. Your outboard stator is the "powerhouse" of your outboards ignition system. That is unless there is an issue with the stator or alternator. Either way, running your outboard without the voltage regulator at high RPMs can cause the stator to fry, leading you to more trouble down the road. Today, he spends his time freelance writing and consulting. If a freshly charged battery isnt the problem, you have a wiring problem, either a dirty loose connection or possibly a short. On newer voltage regulators, there is also a rectifier, which can convert the AC current from the power generated to DC output. Bad voltage regulator symptoms outboard Bad voltage regulator symptoms outboard Most Mercury Outboard Stators perform two important functions 1. So, now that we know some of the differences and similarities in different year/model stators let me list many of the common symptoms of a stator that has gone bad or is going bad: Hard starting: Hard starting when cold or won’t start when cold.
