I lost my Owner’s Manual, where can I get another one?
You can download a copy of the Product User Manual from our website: innova.com/support.

Can this timing light be used on both 2 and 4 cycle?
No, this timing light will work on 4 cycle engines only.

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, ensure 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-1960s vehicles used positive ground systems. Check service manuals for the correct ground systems.

Does my 3555 Timing light work on 2 cycle/stroke engines?
No. The 3555 Timing light does not support 2 cycle/stroke engines. Our 5568 timing light will work on 2 cycle/stroke engines.

Where do I connect the red and black clamps on my vehicle?
Place the RED lead onto the positive (+) side of the battery. Place the BLACK lead onto the negative (-) side of the battery, or the chassis of the vehicle.

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.
