big6 & johnloftus,my battery is very new,the condition of the cables,grounds,and my most favorite healey electrical component the "master batt switch"are all new having redone the entire trunk area this summer,of course that doesnt rule out a poor ground that may have just accured,as for the "dynamo"it was rebuilt/remanufactured just prior to my purchasing the car in may 2005,i have not had a chance to put a meter on it as of yet,but will do so this afternoon,all the lights are bright,and i didnt see a gen.worning light befor or after stepping on the switch.as for the old switch,well ive been taking things apart since im 3 weeks old [literaly] and couldnt resist opening this little jem up, it "was" very cool inside with contacts that flip around and all,but its since been placed in the universal recicle aperture,nothing that could have been saved of it,at least until i got my hands on it!i will take the advice of both you gentleman and explore the generator,grounds,switch,voltage drops etc,ill let ya know what i may find,keoke may have hit it on the first blast "get a different switch from another supplier" /ubbthreads/images/graemlins/yesnod.gif shg's gunna love to hear that one! /ubbthreads/images/graemlins/devilgrin.gif
