FAQs

Is this switch suitable for all types of vehicles?

This switch is primarily designed for competition cars and vehicles needing complete electrical isolation. It is suitable for 6, 12, and 24-volt systems but is NOT recommended for vehicles with alternators.

What is the maximum amperage this switch can handle?

The Autolec Mini Battery Isolator Switch has a continuous rating of 100 amps.

Can I use this switch on a car with an alternator?

No, this specific model (MW003) is not designed for vehicles with alternators. For vehicles with alternators, please use the Autolec FIA Battery Master Cut Off Switch.

What is the terminal diameter?

The switch terminal diameter is 10mm.

How often should I operate the switch?

If the vehicle is in regular use, operate it each time you park. If the vehicle is stored, operate the switch a few times during the storage period to maintain its functionality.

What happens if I install this on a car with an alternator?

Installing this switch on a vehicle with an alternator can lead to system damage or improper operation, as alternators require a continuous circuit to function correctly. It may also bypass safety features.

Troubleshooting

Switch does not disconnect power

Verify that the switch is correctly installed in series with the battery's negative terminal. Check that the switch is fully turned to the 'off' position. Ensure the terminals are clean and connections are secure. Confirm the vehicle does not have an alternator; if it does, this switch is incompatible.

Poor electrical contact after operation

Clean the switch terminals and the battery posts/cables. Ensure the 10mm terminals are securely tightened onto the battery posts. If corrosion is present, clean with a wire brush.

Switch feels stiff or difficult to turn

Operate the switch several times to help loosen it. Ensure no obstructions are preventing its movement. If persistent stiffness occurs, professional inspection may be needed.

Pros and Cons

Pros

  • Provides essential electrical isolation for safety and battery maintenance.
  • Compatible with common vehicle voltage systems (6V, 12V, 24V).
  • Robust 100A continuous rating is sufficient for many applications.
  • Simple mechanical operation for quick disconnection.

Cons

  • Not recommended for vehicles with alternators (requires a different Autolec model).
  • Terminal diameter is 10mm, ensure compatibility with existing battery terminals.
  • Requires manual operation for disconnection and reconnection.

Setup, Compatibility & Care

Setup: Installation typically involves mounting the switch in an accessible location and connecting it in series with the vehicle's main battery lead. Ensure proper crimping and securing of connections to the 10mm terminals. It's crucial to confirm that the vehicle does *not* have an alternator before installing this specific model; if it does, the Autolec FIA Battery Master Cut Off Switch is the appropriate choice.

Compatibility: This switch is designed for 6, 12, and 24-volt systems and is rated for 100 amps continuous. The terminal diameter is 10mm. It is *not* suitable for vehicles equipped with alternators.

Care: Keep the switch clean and free from dirt and debris. Periodically check the terminal connections for tightness and corrosion. Operate the switch a few times annually to ensure smooth operation, especially if the vehicle is stored for extended periods.
