HOLDEN HQ SPARK PROBLEM

1974 Holden HQ

I took the ingintion barrel out as I lost my keys I have been trying to start it with the bar that runs down the steering shaft to the innition switch. My problem is wen I do this the engine winds over but ther is no spark wen u turn the key back to the off position it sparks I replaced the ingnition switch thinking it was the cause but this is not the case plz help thanks jason

Check that you have 12v at the coil pos terminal with the ignition on. Do you get dash light on still?

Check that the switch is actually switching as it should and do a continuity check down the loom from the switch, is it auto or manual? If auto is trans isolator switch ok?

It s a manul I just had a thought would it be doing this if the distrbutor is not timed right. Altho it should be it was running fine wen I parked it up and it hasent been touched since so it should be right but just a thought

I feel that it will be a wiring issue, check for 12 V AT THE COIL WITH THE IGNITION ON
check carbon brush in distributor is ok and not burnt, check points are not closed up.
