Hi, On Volvo truck the engine D-13 begin in 2008 production and the starter is on the passenger side and the only starter relay is bolted on the side of the starter close to the starter solenoid.
On that engine model the starter relay is feed on side (12 Volts) by the ignition switch and the other side (negative) by the engine ECU.
If your engine is a D12D the starter is on the driver side and the starter relay is bolted on the fire wall (engine side) below the foot valve, the positive side of the relay coil is feed by the ignition switch and the ground of the coil is connected directly on the big ground stud of the starter.
Some starter have the OCP Over Crank Protection it's a switch in serie for ground relay supply to cut the ground of the relay (to stop cranking) if the starter temperature comes to hot.
Hope this can help.

Mine went out last Winter. It was on the starter on a D13. Road guy got me started with a big screwdriver to the solenoid.

When you check on the both side of your relay and see 12 volt probabbly your ground circuit come from the starter big ground stud is open or the OCP switch is open.
I recommand you to remove one little wire on the starter relay at the fire wall then with the ignition switch at start position check from which wire the 12 volts is coming ? the removed wire or the wire who stay connected on the relay then you will know which wire suppose to be ground.
Hope this can help.

Hi I have a 2008 D13 that started giving me a engine derate soot high and when I pulled I to my driveway the truck just shut off, no warning or anything, when you hit the key the dash goes completely out and when you release it the dash comes back on. The display when telling me derate soot high to the time it shut down was only 3 miles. Any suggestions?

And it will not start or turn over at all
