New to this forum and have been searching through multiple posts looking for something similar to my situation but couldn't find anything real close. To start I have a brand new battery which is holding at 11-10.8 V while cranking. The weird thing is that I have an inline spark checker and that will flash while cranking (on all cylinders), but if i pull a plug and ground it, it will not spark across the plug. So it seems the stator and cdi or working to fire the coil but there is not enough current behind it to fire across plug. Here are the tests I have done so far.
-Ohm tested trigger coils, and also watched them go from open to around 25 ohms with 9 volts on brown wire
-CDI is putting out 9 V DC on brown wire to stator
- Have 240V at blk/white wire from CDI to coil while cranking. Saw somewhere on a post that you should have 240 on the other three wires as well (blk/grn, y/brn, blk/blu) which i do not have, but that doesn't make sense to me because you would have 240 on both sides of primary coil. ??????
-LR is putting out battery voltage on orange wire while cranking
-Have 11-10.8 V on red/pur wire on terminal block while cranking
-All spark plug wires ohm tested ok
-Coil also ohm tested ok, 1500 on secondary side .2 ohms on primary side(spec is .35 ohms) ??????
-All grounds check good
My gut tells me it may be a coil but it checked ok and since they are kinda rare now it is $180 online so I wanted to get some input before pulling the trigger on it. Just weird that it is showing spark on my tester but not actually sparking. Any help or other testing ideas greatly appreciated. Thanks
