Voltage output is too low

[NoVoltage]

I have a T8 outboard on my sailboat. I've discovered that the output of the leads to recharge the battery in the boat is reading between 0.9 to 1.3 volts depending on RPM.

Unless I'm mistaking, this should be around 14v to charge a 12v battery.

Now, what would be the likely culprit in this situation?

The CDI? The Regulator? Something else? Any additional ideas to help track the issue?

lighting coil or the regulator/rectifier

Thanks for the reply.

Can you enlighten me on how to check if these components are okay? Voltage check? Continuity test? ...
