Duster ignition

You may not need ANY parts

Detail what is wrong. It won't crank? (the engine doesn't rotate on the starter?)

Or it does crank and won't fire/ run?

Sounds like it won't crank (rotate)

The "transformer thing" is the STARTER RELAY

The two small "push on" connectors are the magnetic coil. One of these must be grounded in park / neutral (automatic) or grounded by clutch pedal switch when depressed

The other gets power from key during "crank."

If the starter relay clicks ONCE but the starter does not operate, it is likely a bad starter relay
