Mechanical Inspection: Compression
Check engine mechanical condition using a compression gauge, vacuum gauge or engine analyzer. See engine analyzer manual for specific instructions. Always disconnect engine speed/reference sensor for compression tests, otherwise dangerous high voltages and insulation damage to ignition coil, high-voltage distributor and ignition leads may result.
