A shield can help sometimes. But before I did anything, I would go through and check ALL the terminals- especially the battery cables including the ground.
If you have anything other than OEM-type cables (none of those PO S clamp-on battery terminals) of sufficient gage, you're looking for trouble, IMO. Those clamp-on terminals are the absolute worst
- they can look fine, yet not conduct enough current to heat a cigarette lighter.
Be sure there's ground cables from the battery to the chassis as well as the engine, and from the engine to the chassis. Really, you can't over-do this.
The Ford solenoid conversion is worthwhile. I have a personal theory that a good part of the success of using a Ford solenoid is as much due to the cables getting changed out and tightened, as the solenoid itself.
