chaging system?

[hangup]

does a 1979 mercury 80hp. have a charging system on it ?

Yep should be able to follow the wires from under the flywheel down to the rectifier. I'll look in my book and post the exact location. If you want to check it for charging just take a volt meter and check it at the battery while running. Should read between 13 to 14 volts.

It has a 9 amp system. </p>

While running WOT, that system can make around 16-17 Volts. That is one of the reasons you don't use a maintenance free battery (sealed car battery). It only has a rectifier and not a regulator. At dead idle, it may only show battery volts. The mercury manual want it tested at 1000 rpms after allowing time to stabilize. This depends on battery level. then it should read13-14 volts.The yellow wires under the flywheel will go to the rectifier. With that igniton system,(ADI altenator driven ignition) it is possible for the stator to be bad even though it runs. It has 2 seperate circuits.</p>
