What do I do if my timing light does not turn on?
Make sure the battery clips are firmly connected to the battery terminals. Also, make sure the battery clip polarity is correct (red battery clip is connected to the positive (+) battery terminal, black battery clip is connected to the negative (–) battery terminal).

Does my timing light work on positive ground systems?
Our timing light will only work on 12V negative ground systems. Some pre-1960’s vehicles used positive ground systems. Check service manuals for the correct ground systems.

What do I do if my timing light does not flash?
Make sure the upper and lower ferrite cores of the inductive pickup clip are clean. Also, make sure the inductive pickup clamp is properly connected to the No. 1 spark plug cable and that the arrow on the clamp is pointing towards the spark plug.

What if the Timing Light readout locks up during use?

Where can I find the timing specification for my vehicle?
Consult the vehicle's service manual for procedures and specifications.

Does my timing light work on 6V systems?
Your timing light may be used on vehicles with 6-volt electrical systems by using the following connection procedure: 12-volt automotive battery required.
1. Connect the RED battery clip to the positive (+) terminal of a 12-volt battery.
2. Connect the BLACK battery clip to the negative (-) terminal of a 12-volt battery.
3. Using a length of 18AWG jumper wire, ground the negative (-) terminal of the 12-volt battery to a known-good ground on the vehicle under test.
