Changing the starter on my 2007 Fiat 1.3 diesel. There is no "trigger wire" terminal. Instead the light wire is in a plastic housing which is bolted on under the battery feed.

How does this work?

  • If the images I see are the correct starter, there are two terminals on the back of the solenoid: one where the main power goes in; separate post which provides a connection down to the motor. These types have a separate relay which turns on the juice from the battery. Older Ford starters worked the same way. It looked something like this. Not sure how your Punto is wired, though. – Pᴀᴜʟsᴛᴇʀ2 May 5 '18 at 12:04
