Angry Boat just shut down, help please

27 mach1 with 502, I had problems with the batteries not staying charged before check altenator and wire was broke, fixed it, now sunday I went to leave the dock everything was working I have a good size spot light turned it on before I started the boat it worked fine, left the dock and went to dock for the night and turned on my spot light with boat running and blam shut down everthing except bow lights and trim would work, not dash no start, nothing switched to number two battery and it started for a hot minute and shut down also check fuses, breakers and all that I could, I had tested load tested the batteries and they were fair to good, I know I need new ones, I feel that the voltage regulator was working to hard and it burnt the altenator up because the gauge would go up to about to 13 to 14 amps while the boat was running and then level out to 12 but it would take a while, well any ideas please would help, thank you so much Rico

just a quick guess i would say the batteries probably shorted out inside. you are going to need new ones anyway so why not start there. if they wouldnt take a charge the alternator was already working double time and then the others items just added to the load. keep us posted and bring this to the top this evening and somebody will help out.

Rico -

I agree with Rob - start with the batteries. I assume that you have a 502 EFI/MPI - if so, then without da juice, the computer won't work, and will shut down the fuel delivery, etc. If you don't want to spend a lot of money, just go to Sam's/Costco and buy your batteries. I change mine every year, whether they need it or not.... the few $$ that it costs to be proactive is $$ well spent.

You may need to check the re-set button on the control box once you replace the batts....... its the large RED button - works just like a GFI circuit.....

Good luck.

i doubt the alternatot went up but after installing batteries and get it running you will know. the fact that you say how rough it was out therewhen this happened just reassures me that the batteries are where i would start.

Rick, I'll have a spare alt w/me at the river tonight. Not sure what your problem is. Is it possible that a ground cable was left off one of the batteries and you were switched to that one? Call my cell if you want it. 201-522-3512

It is possible for batteries to short internally, yes, but two at once??? It is possible, but if the boat has a fuseable link you may want to check that also. A voltage surge can pop those and create a headache for the person diagnosing it. Just a thought.
