Anybody able to help ?<br /><br />60hp Chrysler 609HA ( Yes I know it was born before the T-Rex ) I have spark to only the<br />top cylinder.<br /> Tested the coils and they both work, I swapped the cables over and got a spark on the bottom<br />coil. Although the bottom coil had the earth to the + side, so I swapped it to the correct side (<br />I hope this was correct).<br /> Was told to arced out the two points on the under the fly wheel at 7 O’clock and 8 O’clock<br />(T1 & T4 ? ) to test the CDI. These both gave a nice big blue spark.So am lead to believe the<br />CDI is ok.<br /> Two Questions, Did I do the correct things above ? And does this show the power pack is the<br />problem.
