Frequently Asked Questions

How many electrical parts fit the 1973 MG Midget?

Our catalog currently lists 52 electrical parts for the 1973 MG Midget across 9 subcategories and 16 brands, covering the 1.3L L4 engine. Each part is matched to the engine(s) it fits.

What are the signs of electrical problems on a 1973 MG Midget?

Common symptoms include slow cranking on cold mornings, a battery light that flickers, dim lights at idle, or a check-engine code pointing at a sensor circuit. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

Where labor overlaps, clean or renew the battery terminals and grounds with any charging-system repair.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1973 MG Midget was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 1973 MG Midget?

Every part on this page is matched to the 1.3L L4 engine. Then test before replacing — a failed alternator and a bad ground can look identical, and sensors are frequently condemned for wiring faults. The notes column carries position and trim qualifiers where they apply.
