Safety Warnings and Precautions

WARNING: When using product, basic safety precautions should always be followed to reduce the risk of personal injury and damage to equipment.

Read all instructions before using this product!

1.

Keep work area clean. Cluttered areas invite injuries.

2. Check for damaged parts. Before using any product, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function.

Check for any broken or damaged parts and any other conditions that may affect its operation.

Replace or repair damaged or worn parts immediately.

3.

Replacement parts and accessories. When servicing, use only identical replacement parts.

Use of any other parts will void the warranty.

4.

Always check hardware and assembled parts after assembling. All connections should be tight and hardware tightened.

5.

Keep children away. Children must never be allowed in the work area. Do not let them handle the Circuit Testers.

6.

Dress properly. Wear restrictive hair covering to contain long hair.

7.

Use eye protection. Always wear ANSI approved impact safety goggles when using this product.

8.

Maintain product with care. Store the Circuit Testers in a dry location.

9.

There are certain applications for which these Circuit Testers were designed. Do not modify these Circuit Testers and do not use them for a purpose for which they were not intended.

10. Do not use the Circuit Testers if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgement or reflexes are impaired while taking drugs. If there is any doubt, do not use the Circuit Testers.

11. Maintain labels and nameplates on the Circuit Testers. These carry important information.

If the labels are unreadable or missing, contact Harbor Freight Tools for replacement.

12. The Circuit Testers should be kept away from children.

WARNING! Risk of explosive gases:

13. Working in the vicinity of lead-acid batteries is dangerous. Batteries generate explosive gases during normal battery operation. For this reason, it is of utmost importance that each time before using these Circuit Testers you read and understand all safety warnings and precautions as outlined in this manual and those manuals published by the battery and vehicle manufacturers and manufacturers of any equipment you intend to use in the vicinity of the battery.

14. Make sure someone is within range of your voice and close enough to come to your aid when you work near a lead-acid battery.

15. Keep plenty of fresh water and soap nearby in case battery acid contacts skin,

clothing, or eyes. Avoid touching eyes while working near a lead-acid battery. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters the eyes, immediately flood eyes with running cold water for at least 10 minutes and get medical attention immediately.

16. NEVER smoke or allow a spark or flame in the vicinity of a lead-acid battery or vehicle engine.

17. Use caution to reduce the risk of dropping a metal tool onto a lead-acid battery. The tool may spark or short circuit the battery or other electrical part that may cause an explosion.

18. Remove personal metal items such as rings, bracelets, necklaces, and watches when

working with a lead-acid battery. A lead-acid battery can produce a short circuit current high enough to weld a ring or other metal item, causing a severe burn.

WARNING! Operate a combustion engine only in well-ventilated areas. A running engine produces carbon monoxide. Carbon monoxide gas is colorless, odorless, toxic gas that can cause serious injury or death.

WARNING: The warnings, cautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

Operation

Your Circuit Tester comes completely assembled. It is important that you read the entire manual to become familiar with the product BEFORE you use the Circuit Testers.

The 3 Piece Circuit Tester Set contains each of the following Circuit Testers:

A: Self-Powered Electrical Continuity Tester. Use this tester to test for continuity with the power disconnected. For use on recreational and general automotive vehicles.

Operation: This Tester requires one “AA” battery. Disconnect the vehicle battery. Attach the Alligator Clip (12A) to a ground of the vehicle, such as the vehicle’s body. Poke the tip of the Probe (1A) through the wire’s jacket and touch the metal of the wire. If the circuit is complete, the Bulb (7A) will illuminate; this indicates there is electricity flowing through the circuit. No illumination of the bulb indicates no electricity flowing through the circuit and that repair or replacement of the components being tested is needed.

B:

C.

Heavy Duty Circuit Tester (Green) for 18, 24, and 36 Volt systems. Use this tester to check

AC or DC wiring up to 36 Volts. Use to check series-parallel switches and solenoid on tractor-trailer starter systems.

Operation: Use this tester with the battery connected. The vehicle does not have to be running. Connect the Alligator Clip (11B) to the vehicle as a ground; or connect it to the negative battery post. Poke the tip of the Probe (1B) through the wire’s housing and touch the metal of the wire. If the circuit is complete the Bulb (6B) inside the Handle (7B) will illuminate; this indicates there is electricity flowing through the circuit. No illumination of the Bulb (7B) indicates no electricity flowing through the cirecuit and that repair or replacement of the components being tested is needed.

High and Low Voltage Tester: Use this tester to check primary circuits of 6 and 12 Volts. Use to trouble shoot both primary and secondary circuits. On secondary or high voltage circuits you can check spark plugs or distributor caps. To test spark plugs and secondary (ignition) circuit, do not ground clip. Attach clip to nose of plastic probe housing. With engine idling, run probe of tester along wire from distributor to plugs. To test plugs, insert probe through plug cap. Extreme brightness of long bulb flashes is sign of high resistance or plug gap is set too far apart. Bright even flashes indicate normal ignition. Extreme dimness indicates low resistance and means carbon deposits have formed on plug electrodes or plug is not firing properly for other reasons. Remove plug for closer check after cleaning.

SKU 94130

To avoid serious injury form electrical shock,

DO NOT TOUCH the probe with your bare hands while preforming high voltage test!
