WARNING: This page is about a different car, the 1994 Mazda Protege, 1994 Mazda MX-3, and 1994 Mazda 323. However, it is still accessible from the selected car via links, so may be relevant.
- With relay connected, ensure battery voltage is present at relay terminal White/Red wire on MX-3. For locations of circuit opening relay, see CIRCUIT OPENING RELAY LOCATION table.
- If voltages are okay, remove relay from vehicle. Using a 12-volt battery source, connect 12 volts to relay terminals "A" and "B". Ensure continuity is present across terminals "C" and "D". If continuity is not as specified, replace circuit opening relay.
