Hello!
New motor for me, new to outboards.
How do I easily tell if the engine is charging the battery? I suspect a problem, the boat came with a new battery when I bought it. I don't want to launch the boat for the summer and find out it has a charging issue. I have been sorting out a non-functioning tach on the boat and since its related to the charging system I am getting concerned that it may be the stator/rectifier, not the tach.
Today I checked voltage at the battery with the motor not running, 12 volts, started motor, still 12 volts and used the tilt to put a load on the charging system. Meter went down to 11 and back up to 12. I have alot of experience with cars and would think the engine would put out 13-14 volts when running? I then found the rectifier. The seloc manual had a procedure to check for conductivity but the diagram/chart had 2 green wires, two red wires, one black. Mine had three green wires, one red and one black. So I am at a loss on how to proceed.
Can some give me a practical way to confirm that the charging system is working? And then if not how to troubleshoot next? I don't want to find out the engine running solely a new battery (no charging) and it dies a few hours on the water. (there is no meter on the helm). This is an electronic ignition 150HP 1990 yamaha.
Thanks!
