Clean up all that magneto !! check coils, plug wires condensers points etc...
dowload this book still good enough...
chat GPT says it is a voltage regulator not just a rectifier.
static battery voltage should rise when the engine runs. if not bad regulaor or lack of AC from stator... check ALL connections !!
see parts list... expensive little thing... not OEM but amazon has cheaper stuff to do the...
3 phase rectifier need 3 yellows carrying each stator AC power at 120 degree phase difference..... each positive phase routed out to the battery for charging.
you could try a 3 phase rectifier from amazon as a test (dirt cheap and higher capacity handling fwiw...) it won'T regulate but...

if heat does not work try freezing... a keyboard dust spray can.....can cool things down fast A can from a dollar store will shoot pure spray held upside down and should help... spray the bolt only then heat up the FW fast to create a shock....try puller while heating...
that should be #2 possible open/shorted injector or ignition coil
you need EV diagnostic to get the code to be specific or... start testing ohms values on inj and coil primaries.... & compare to specs. see manual
if all good electrically ohms wise..........inj. could be...
being an ETEC look at the side LEDS on the EMM (CPU) when you run the engine. report findings top to bottom leds at
KEY ON....
Running.....
motor may be entering SAFE mode with max rpms around1800 due to a sensor fault code!!
to service ETEC you should get EV diagnostics to look...
oil recirculation to prevent puddling is even built in modern ETEC engines and a concept going way back on oldies. You likely have more than one such "small hose" on your 200hp as shown on an 200hp ETEC ..
On small engine push and pull from crankcase pressure-vacum pulse migrate the oil to the...
download you service manual from this list... pretty sure it covers testing the display if not well the file will be usefull for other things. the display is pretty much still used on medern etec evinrude engines. if the suggested manual does not cover testing the dispaly by grounding...
