Evinrude 115 low voltage

[Ray Zor]

1994 115 will not put out more than 13V.<br />Replaced regulator twice. Output voltage from stator assy to regulator is approx 300V<br /><br />Also, engine will only start when trimmed up as if too much water pressure in out drive causing not to start.<br /><br />Any ideas. <br />My first post.............<br /><br />Thanks in advance.<br />Ray

Hey Ray,<br />How charged up is your battery? It may not need to put out more than 13 volts. Is your battery going dead?<br />As for starting only when tilted up, could be that the float(s) are stuck open letting the engine get too much fuel when the carbs. are level. Just a thought.

What rpms are you checking the voltage to the battery? There are other tests, but it should make about 14.5 volts at 4500rpms, with a good meter and battery.

Almost,<br />Battery does run completetly down eventually and must be charged. The battery is new and will hold a charge when charged at home.<br />Good thought on the carb floats.<br />It is my father-in-law's boat and I believe he said he has to tilt engine mainly when engine is cold or has been not running for an hour or so.<br /><br />Clanton, We checked output at various rpms.<br />I would think it would be around 14v above 3000 rpm.<br />Next step is to check with series connected ampmeter. I believe it should be around 9 amps with a weak battery.<br />Also, would anyone recommend checking voltage with batt. disconnected? I don't want to fry any electronics..............<br /><br />Thanks Guys.<br />Ray

Checking your system with the cables connected is a no no. It won't tell you anything, and may damage accessories. <br /><br />As stated, check the voltage at the battery at WOT and check the current at this time as well. An amp-clamp will make your life easier....<br /><br />If the voltage is low and the amperage is zero, check for a/c voltage between the 2 yellow wires coming from the stator, going to the reg. If you have low or no a/c voltage, the stator is in question......
