Timing and Spark Tester

[Oldsaltydog]

When doing a "static" or cranking timing test, the repair manuals recommend using spark testers. Does this mean that I take the regular spark plugs out and use the type of non-inline spark tester that is grounded with a clip to the motor? Please advise.

Any way you can ground the wires will work, be it a jumper from the wires to the block. Just so they are grounded.

That is good advice about grounding, Rick, and I appreciate it. In the Seloc manual the plug is still shown installed in the head. Is this correct, or should the plugs be out for the cranking timing test? Thanks!

Leave the plugs in. No problem.
