purple wire) lights up fine but the solenoid wouldn=E2=80=99t actuate. I te=
sted the solenoid (Moss =E2=80=93 aftermarket) on my workbench and it seems=
to pull in fine. It probably only has 5,000 miles on it and looks almost n=

it still doesn=E2=80=99t actuate, although I can move the actuation lever =
by hand. Evidently the solenoid is bad again. It seems like I go through OD=
solenoids fairly regularly. Randall (does anyone know how he is doing???) =
had me install a small =E2=80=9Cbounceback resistor=E2=80=9D on the from th=
