Re: PCM Solenoid Fuse
Far and away the most common reason that I've seen cause the PCM or VRM loose power is that the fuse is not properly installed.
The terminals that the fuse connects to are not perfectly centered in the hole. So many teams insert the fuse and when the fuse body hits the RoboRio's case people call it good. You must wiggle the fuse/deflect it to the side so that the fuse body can go into the slot. A fully inserted fuse has about half of it's body below the top of the RoboRio case.
As an inspector I've seen properly inserting the fuse to fix the loss of power to the PCM and VRM a number of times.
