Thanks for the heads up.
I've pulled almost all the electrical stuff off my 85 parts van. I'll
double check condition of things before swapping it over.
With a Vanagon that *may* have a poorly maintained cooling system,
that rad fan motor would see a lot of action. (poor cooling could be
one reason why those poor vans ended up in the yard? --- ;^)
