Hello everyone , this is my first post as I just signed up , I'm hoping to get alittle help here from someone who might know anything about what I have going on . The boat is a 2008 superair 210 team edition with the 343 pcm motor . Factory wiring , factory stereo , factory clarion amps and sub , basically everything stock and untouched . Boat has alittle over 150 hours on it , never had an issue until yesterday .
When I purchased the boat new , I opted to not install tower speakers from the factory but it was pre wired through the tower for them from the factory. This past week I finally bought some tower speakers and hooked them up to the factory tower wires coming from the factory clarion amp and went out on the lake . The boat ran fine for 3-4 hours never missing a beat and speakers playing just fine . We had stopped for a moment to change riders while wakeboarding and when I went to take off to pull up my rider I noticed the check engine light came on . I shut the boat down right away , opened the hatch and checked the engine , everything seemed fine so I fired back up , the engine light went away and I began to try and pull my rider again , this time as soon as the boat was almost on plane , the light comes on again and I notice the voltage meter is pegged at 16+ .. I shut the boat down again , checked the battery connections , everything is connected right and tight , everything is freshly charged and they are holding close to 13 volts with the engine off .. At this point , I'm a long way from the boat ramp , and I'm just trying to figure it out on the water without much tools or help from anyone so I began singleing things out , I first turned the stereo completely off , and tried again to run the boat , but once again as soon as the boat takes off and the rpms raise up the voltage pegs and the light comes on . I did this a couple of times with different things , trying to narrow it down , but no matter what I turned off bilge pump , stereo , switching different battery banks , etc , nothing would stop it from pegging the voltage meter . While the boat idles , it idles at 13.5 volts like normal , but as soon as I fed it the throttle it would peg the voltage meter , so at this point it was getting late , we had a LONG ride back home at idle , maybe 2 hrs if we would have crept all the way there , so I opted to try and disconnect the alternator and see what happens . I unhooked the alternator , accelerated and the boat ran fine , no check engine light all the way back to the ramp and I got it on the trailer .
Im not sure if this is an alternator issue or not , I'm really confused by the voltage pegging out . I've had many alternators die , but they always did the opposite , they drained the system , not overcharged it ? Is this even possible , I'm no mechanic , but I know there is a voltage regulator , is it possible that it's bad and this in return doesn't let the alternator know when to stop charging and its pegging the gauge ?
I guess I need to start by checking the voltage coming off the alternator with a meter , I plan to do that tommorrow , is there anything you guys may know that can help me along if I have good voltage coming off the alternator ? What would cause this problem ? I mentioned the stereo , but I think it's just a coincidence that I hooked the speakers up the same day this thing messed up , the amps have always been installed since day one and have always been on since day one , the only difference in the whole situation would be that now I have 2 amps pushing speakers instead of just the 1 , but that amp has always been there and been hooked up and running . Any help is apprecited , I'm so confused by this problem , I've never had one overcharging ? I've searched through a lot of forums and can't find anything about a voltage Gaige pegging out .
