Duster should have been a DEMON! Cranking issues!

anyway! I get 2.2 volts at starter engagement connection on relay,



I have no idea what this (above) even means.

What are you calling "subframe?" K member? Front frame rail?

The steps basically are

1....Make sure the battery is "up" that is charged

2....Have battery load tested. This requires a device known as a "carbon pile" and is as "big as a bread box"




3.....Measure battery voltage during crank, RIGHT AT the battery posts

4.....Measure starter voltage between large starter stud and engine block, compare to above.

If you have less than 10.5 at starter during crank, you have a big problem.
