Maximum voltage rating ?

I have only used this on 24VDC systems.

Does this item come with test leads?

No, just the box. It uses standard banana test ends.

How would you set this to, say, 350 ohms? Or any value containing a digit greater than 4? Just don't?

The values are cumulative, to get 350 Ohms you would switch the 300, 40, and 10 OHM down. To get a greater the 4 value you would just switch the needed values on. This item has a range between 1 to 11,111,110 Ohms

Will this unit provide a stable signal on automotive circuits?

This is a typical decade box that will provide the resistance you need for testing purposes. I have used it to simulate different devices in the testing of DC control systems.
