Hi all,<br /><br />I have a 1996 Yamaha 115HP V4 (model 115BET) and I used a digital multimeter with the engine off and the battery posts reads 12.66V. I started the engine and the voltage reading is the same even if I accelerate it.<br />My tachometer don't work too.<br />I have checked for any corroded connection and all is ok.<br />I suspect that the problem could be the rectifier regulator or maybe the stator under the flywheel.<br />How can I test with a multimeter the rectifier and/or the stator ?<br />Please include (if possible) the details about the tests, including color wires and a diagram if possible.<br />My Rectifier has 2 green wires coming from the stator and a brown wire and a black one.<br /><br />Thanks in advance for any help.<br />Abel.
