hi this is my first post here hope i'm in the right spot. I picked up a non running 88 ds80 for my daughter as she is out growing her 79 jr50. The previous owner said it lost spark one day and he had a friend look at it. he cut and spliced all the wires and it sat for 5 years. something seems odd about it. i changed the coil because i had a good one laying around. Took the flywheel off cleaned it and noticed the earth black/white was running to the coil and the lighting hot wire yellow/red and ignition hot black/red were both running to the light switch. i proceeded to check the voltage on the black/red which the fiche shows running to the primary coil on the stator. It showed 16.7 ac volts. I hooked it up to the new coil and nothing. My question is how many volts am i supposed to have to the coil? I am afraid to buy a manual because it has no carb on it and if it needs a stator too i will have to part it out because i cannot afford to buy both. any insight is greatly appreciated. btw it is in good shape except for the brake, throttle cable and missing carb oh and no spark. is 70 us dollars a fair price or did i get taken?
