Tried a boost. No click no action.

Here's what happens with key turn sequence:
- normal lights across the dash come on
- glows come on for their timed period, waiting
- finish turning key to start position
- no click, no action
- when key is in start position, I notice lights across the dash dim as if solenoid is taking power and lights re-brighten when key is released

At this point I think I have a stuck starter solenoid in the engaged position, or a burnt solenoid coil that is shorting and therefore can't engage.

Thoughts?

Anybody know if there's a big fuse or some thermal cutoff between the battery/key/solenoid/starter combo that I should be checking before I get towed to yank the starter out?

THANKS!
