Cat Lift Trucks (& Caterpillar) GP40:
No spark 6G72 Mits engine

Hey, GP40 Ser31CM03035

I have no spark from coil, checked power at coil terminals. it lit up my test light at both terminals. checked all fuses all ok. removed cap and checked all ok. went back and tested power at terminals on coil again and now i had nothing. checked the black wire to the ignition module and have power there, nothing on the other wire going to the coil. Not sure what the other 2 wires are on the coil are for. Just wondering if anyone has a schematic/trouble tree diagnosis for the ign system?
Thank you
