Tune-Up Notes
NOTE:
In order to comply with emission standards, I specifications shown on engine compartment emission control tune-up decal must be used in all instances.
CAUTION:
Before making a compression test or cranking engine with a remote starting switch, disconnect ignition switch connect (pink wire) from H.E.I, system.
CAUTION:
Do not remove spark plug wires with engine running. High Energy Ignition secondary voltage is higher than standard ignition systems and may inflict harmful electrical shock.
CAUTION:
Damage to H.E.I, electronic module and/or ignition coil may result if "TACH" terminal, in distributor cap connector, is directly grounded.
