I recently purchased a used 93 TRX350. Ran great. 2 days later, would not start due to no spark. I started by checking the engine stop switch (OK) the went looking for a loose/cut wire. Found it! Worked great for 2 days then again no spark. This time I again checked for loose/broken wires, fuses, coil resistance, engine stop switch, etc. Found nothing. When checking voltage at the ICM I have power going in but no power out to the coil. Can someone please let me know how I can check that the ICM is still OK short of buying a new one just to try it out.
