coil question
#11
I had a stock tb 4 when I dynoed the engines.I ran the marine MSD coils with those distrb. and it worked great.I then change out the ditribs for the MSD ones and used the same coil with them.No ballast resister on either system.

I Have Another Problem, Can You Lay The Coil On Its Side? Out For My First Run Today And Turned The Motor Of To Check Everything Only To Findout Now No Spark On A Restart. 20 Minutes Later She Gets Spark And Runs Only To Do It Again After A Shut Down To Check To See If It Will Restart And Again No Spark? What Gives? Called Msd And They Advised To Stand The Coil Up If Its An Oil Filled Coil. Possible Thunderbolt Module Trouble ?
