When I turn the key the starter clicks once.
The engine does not turn over.
I have checked the electrical connectionals.
The smaller red wires that go into the engine compartment are cooroded.
This has steadily gotten worse.
I used to be able to wiggle the wires on the starter and it would start.
Now that it is real cold it just clicks once.
I don't think the starter coil itself is getting any power.

I have the bently CD for this but I'm not clear on how this works.

I do have a flakey nuetral-park switch.  But as long as the starter clicks
I think the switch is working?

Thanks for your help.
