low spark at all plugs thinkin low or no stator output. is it more likely the switch box (thuderbolt cdi)? havent got elaborate test eq but do have good multi meter. any suggestions appreciated, thanx old man river

take the green/white and white/green wires loose from the the stator bullet connectors and test they should be between 500 and 600 ohms.

glad to report im back on the river. got lucky and found a motor with blown power head. was able to swap out stator and switch box along with trigger assy. stator ohm reading was showing a dead short so we swapped it out with trigger assy. motor ran but real rough. we then swapped switch box checked timing and now motor runs like new. thanx, old man river
