Detailed Description

Standard Ignition NS-47 is a neutral safety switch used in the starting circuit to help ensure the vehicle only cranks in the proper transmission position. It is listed for 1988-1990 Chevrolet Corsica and 1988-1990 Pontiac Tempest applications, including specific configurations such as vehicles with wire connections and models noted with Canada emissions or radio capacitor harness requirements. This part cross-references 1S5217 and DR465 for the same application. The NS-47 is a practical replacement choice when servicing a Chevrolet Corsica or Pontiac Tempest with the original switch style and connector layout.

Common Issues This Part Can Address

• No-crank condition when the shifter is in Park or Neutral
• Intermittent starting caused by worn internal switch contacts
• Incorrect starter engagement due to failed transmission position signaling
• Electrical connection problems at the switch connector or terminals
• Starting circuit faults on select Chevrolet Corsica and Pontiac Tempest models

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle-specific notes before installation. Confirm the transmission is in the correct position and inspect the harness connection for corrosion, bent terminals, or damaged wiring. For best results, compare the original switch layout to the NS-47 before final assembly.
