Using Your Timing Light

TIMING LIGHT CONNECTION

To ensure personal safety and reliable operation of the timing light, use the following procedure to
connect the timing light:
Always keep hands, timing light, lead wires and clips away from moving engine parts and
hot surfaces. DO NOT SMOKE.
1. Turn the ignition off. DO NOT CONNECT THE TIMING LIGHT WITH THE ENGINE RUNNING
OR WITH THE IGNITION ON.
2. Clamp the inductive pickup clip around the
No. 1 spark plug wire. See Figure 3.
DO NOT ALLOW THE INDUCTIVE PICKUP
CLIP TO CONTACT THE EXHAUST
MANIFOLD OR OTHER ENGINE PARTS.
These parts become EXTREMELY hot while
the engine is running, and will damage the
inductive pickup clip.
3. Connect the battery clips to the vehicle's
battery:
■
Connect the RED battery clip to positive
(+) battery terminal.
■
Connect the BLACK battery clip to
negative (-) battery terminal.
4. Connect the inductive pickup leads to the bottom of the timing light handle.

INITIAL (BASE) TIMING CHECK

Some ignition systems require that certain components be disconnected, jumped or grounded
BEFORE ignition timing can be checked or adjusted to specifications. If these procedures are not
followed, the checked or adjusted timing will not be correct. You MUST consult your vehicle's
service manual for the proper procedures and specifications.
1. MAKE SURE the timing light is properly connected as described in TIMING LIGHT
CONNECTION.
2. MAKE SURE the engine has been properly prepared for the timing check as described in
ENGINE PREPARATION BEFORE TIMING.
3. Start and run the engine until it reaches its normal operating temperature.
4. Adjust the engine's idle speed, if necessary, to conform to manufacturer's specifications:
5. MAKE SURE the timing light Advance Display shows 0 (zero) degrees. Press the Zeroing
Switch if necessary to obtain 0 degree indication.
