SOLVED: Location of Starter Solenoid Switch: 2006 F53

I was debugging an intermittent no crank problem and wanted to have a look at the Starter Solenoid Switch. Parts.ford.com says I have one but does not suggest a location. For various year F53s, some say passenger wheel well, radiator area, etc, but I don't see it. Following the positive battery lead or the starter positive lead is difficult and not helping. Does anyone have a location suggestion for the 2006 f53?



I generally like shop manuals and I assume they would suggest where it is located, however, prices for this one range from $700 - $1000 (amazon, eBay). Does anyone use the Chilton DIY service? Not sure if they would show such a thing but they are more reasonable.

thanks very much for any ideas,

  • According to photos on Rockauto, the Ford starter has a solenoid similar to GMs.
    Small relay is in control circuit and not the power circuit to operate starter motor.
    Earlier models did have full amperage starter relays.
  • There's no way that relay will handle the starter current. Keep looking.
  • Thanks everyone for the advice.

    I was able to determine that somewhere between 2004 and 2006 they got rid of the traditional starter solenoid switch and replaced it with a starter motor relay. It is in a relay compartment on the exterior firewall. I was just looking for the wrong thing that would have large cable going to it.

  • Most of the relays adjacent to the batteries are battery disconnects.
  • Pretty sure mine is located in with my batteries, never really gone looking for it just general observation from memory when I've been working on the batteries.
  • Trace the large cable from chassis battery or trace battery cable back from starter.
