LA 318 Dying when put in gear and high idle issue solved!

pickup resistance should be between 350 and 550 Ohms. Its just a ferrite core wrapped with some super thin ~40G wire, I'm not sure if it could be bad unless the potted wiring is shorted internally during production. Its like a guitar pickup, the more windings it has the more it will amplify the signal from the reluctor passing through its field.
