"Excellent and thanks. Will test coil resistance. Ok now trying to get at the root cause to avoid a repeat. I think we can rule out cause 1 and 3 because the battery was not reconnected any time recently and I have been running off the battery and manually charging and using for an hour or so. Number 2 sounds the most likely and probably has the most chance for reoccuring if I don't find the short. If the short occured inside the regulator then the short is fixed with the new regulator. If it occured external to the regulator then I still have a potential for a repeat, unless I find it. The battery seems an unlikly place to look. It is contained in plastic battery box as it came from the boat dealer (fisher pontoon boat). This means that I am looking for regulator wires that came in contact. Ok by installing the new regulator I know that the two yellow wires were melted together. Based on what you said those are coming from the stator. I had assummed that they were melted from the heat that melted the inside of the regulator, but this could be the source of the short. By the way there were no markings I could find when reconecting the yellow wires to the regulator so I assumed it did not matter which was which. Bad assumption? There were also 2 redish wires a grey and a black ground. Each of the remaining wires could only be connected one way and had some heat damage but not as bad as the two yellow. I reconected all the wires and individually wrapped with a lot of electrical tape due to the heat damage to the factory connector electical insulation. Ok so the stator is a coil generating unregulated AC current to the yellow wires. Yellow wires allowed to short and takes out regulator and stator at the same time. Is this it, or have I missed the boat."
