Gary,

maybe you are right, but I am guessing its the solenoid only. Couple of
reasons.

1. the starter itself as designed is pretty much a dead short, i.e. it draws
a lot (technical term "butt-load") of current .
I think the power rating for the diesel starter is 2.3kW or is it (1.7kW?),
that equals a current draw (at 10V) of 170 to 230 amps. The contacts in the
solenoid are pretty well taking as much as the battery can give! Plus the
contacts close when solenoid is tested (minus internal spring) and have very
low/no resistance.
(My starter spins quickly and promptly in the van and on the bench.)

2. just back from picking up solenoid. Talking to guy at the shop and I
explained the symptoms. He said there are actually 2 windings in the
solenoid "pull back" and "hold back". I think one of the two windings on my
unit was shot.

Anyhow, will slap it in the starter and bench test this morn.

At $29.95 its worth a try.

Alistair
