What is the best way to perform engine compression test with regard to
The last time I performed an engine compression test was on engine (~1980)
that has a distributor and round ignition coil. I would just disconnect the
wire from the ignition coil to distributor then test each cylinder with a
compression tester (all other spark plugs removed from the engine so ther
starter would not working too hard for nothing).
Now my car has ignition modules. Should I disconnect ignition fuse? or
route the spark plug wires away from my tester and crank away?
