Hi Pault,
Thanks for that heads up, it is a timely warning,
Would you please tell us what your ride is (year and model) and what extra electrical mods. it has , as to indicate any extra load or demand that might be placed on to the alternator output.
This is just to give an idea as to how adequate the origional plugs and wiring can cope with any extra loads etc, if that is a possible cause of this type of problem (failure)
Cheers , Winston66
