Hey Everyone,<br /><br />I'm sure you're all going to say sure, sure... 
when you read this but a good friend of mine (not me) and his 16 year old son was helping launching his sister-in-law's newly acquired 2000 Larson ski boat with a 2000 Johnson 130 on it's maiden voyage (she just bought it used) and reverse connected the small leads going to the battery and made a few sparks happen. Apparently, his sister-in-law's face looked kind of like this when he told her what he had done.<br /><br />It wasn't the heavy main leads that he hooked up wrong it was the secondary set with only smaller sized wires that he hooked up backwards. He said a lot of the wiring going towards the gauges got fried all crispy-like and all or most of the fuses up front were blown. He couldn't tell if the wiring going into the gauges was also blistered or burnt.<br /><br />My friend, whom I'm going to call "Sparky" from now on, has asked me to post this message and ask the following questions for him:<br /><br />Has anyone has ever done this before and what was the extent of the damage that occured as a result or does anyone know what the extent of the damage is likely to be in this situation ? <br /><br />Is it likely that the instruments would've gotten damaged or would they likely have been saved by the fuses ?<br /><br />What about the electrical stuff on the engine ? I'm only familiar with the old mid 70's engines so I don't really know what's what with these fangled new oil injection cappucino making models. Would any of the wires on that secondary harness go back to the engine or is all the engine stuff powered off the main leads ? Do these new models still have pulse-packs and rectifiers like the old ones did ? He says there's tons of wiring on that engine so I assume there's all sorts of good stuff in there that one could fry eh ?<br /><br />So is my friend probably just looking at having to replace the wiring harness for the gauge package and maybe some wiring for some of the other accessories or is he more than likely looking at having to replace most of the instruments too ? Is it likely that he fried some stuff on the engine too ? If so, what would be getting power off that secondary (small) set of leads going to the battery ?<br /><br />I'm sorry I can't give you more technical details to help you make more educated guesses but you now know everything I know about the situation so please just try and do the best you can based on the little bit of information you have to go on.<br /><br />Thanks<br /><br />Roj (Roger) on behalf of K. "Sparky" Mathewson<br /><br />"Hooo-boy, that blowed up reaal gooood !"
