2004 rancher 2wd 350ES not running
 

TRX350ES cranks over and sputters but wont run.
1. replaced battery (still nothing)
2. made sure it was getting fuel
3. rebuilt carb (still nothing)
4. checked compression (90psi)
5. even replaced carb (still nothing)
The only thing that happened at the near or the same time is the dash went completely dark. Any suggestions on how to test the ICM and or Ignition pulse generator?

First thing to check is if there is a good spark. If you have a good spark, there is no need to check the pulse generator. 90psi isn't all that good, though having an auto de-compressor tends to make the figure a bit low. Check and reset the valve clearances, this could help the compression.
