Here?s my story, out boating in the bay for about an hour in fairly rough water. Anchor by a small island, few hours later, go to start and starboard motor fires then dies, repeat, fires then dies, repeat the process same result. Start port motor and go home.
On the lift, check spark, got it, check fuel in carb, got it. Change fuel filter, check fuel from filter, no water. Start motor, runs about two minutes, stalls. Try to restart, fires then dies, fires then dies. Come in, check forum FAQ, discover that starter provides power to fuel pump then changes to alternator. Remove alternator, have tested, guy says no output, thinking I?m on right track, replace alternator.
Start motor, runs about two minutes then stalls, during which time I glance at voltage gauge looks like 10.5 to 11 volts, but this is right before motor stalls so I am not sure if that was accurate. Try to restart, fires then dies, same story. I see in FAQ that a diode may be bad, problem is, I have no idea where this diode is, excuse my ignorance, or what it looks like. I should add, I replaced relay from port motor, no difference. Also port motor runs fine so I am ruling out fuel tank vent. Any other ideas? Where the heck is this diode and what does it look like? Sorry I am at work and do not have serial number.1998/99 Volvo 4.3GL. Thanks in advance.
