Thanks Pete and Quinner. I missed that used one in Quinners original post. I'll probably pick that one up and then take some time to see if I can get the original back to functioning.
Thanks!! Kyle |

Kyle,
It sounds like the auto supply simply checked the output, didn't get a good result and simply called the alternator bad. There are plenty of online videos that walk you through both testing and repair. They show and explain way better than I could in words. Complete kits are available for total rebuilds. A couple example kits:   If you do consider a repair and do find the diode bridge is the problem, then they are available as a simple assembly. Here's one example:  Yet another option is to take the alternator into an "automotive electric" shop. They will test, determine the exact problem, install the needed parts or do a complete rebuild. |

They didn't have the ability to specifically diagnose what went wrong. Any chance I can do that myself and order the part?? Where do I start?
Thanks, Kyle |

Kyle, What was the specific failure? A diode bridge module is cheaper than the complete alternator!

Took the alternator off and in to Oreilley to test. Failed. I guess I'll be ordering a new one from nautiqueparts.com!

If the Alt is shot check over on PN, seem to remember seeing an ad recently for a new or lightly used one that should be a direct replacement.
Have you checked with your local NAPA to see if they can test it for you?? |

So we dropped my cousins boat in the water yesterday. Anytime I can remember it the gauge showed over 14 v when running. After turning on a ballast pump, I watched the gauge drop to 11.8. Confirmed this on the tac digital read out also. While running, I Checked voltage at each battery. Each was at 12.1. Isolation switch was on 1+2. Checked voltage wire at alternator - 12.1. Checked voltage at alternator output - 12.1.
Shut off engine and did the same. Voltage was +.2 volts all the way around. My thought is that the alternator is smoked and that's where I need to start the diagnosis. Thoughts?? Kyle |
