The warning light on the dash of my '96 ranger 4.0, auto with 233k miles started coming on. The only thing I have done recently was to replace my battery. Just trying to figure it out. Any ideas or worries? Thanks.

Start it up & the light should flash a trouble code. Flash flash pause flash flash would be a code 22. Post the code here.

 

yep I got a 2-7 code and it is a bulb in the on /off switch for the passenger side air bag ,,, bulb is a couple bucks but I just keep forgetting to pick one up

 

It seems to be intermitent. This morning it was off after starting but came on a few minutes down the road. It started blinking 3 flashes and then a pause. Repeated a few times and then stayed on constant. This afternoon it never came on.

From your description it sounds like it's blinking a 33 code. If so, that's for the passenger side air bag if the vehicle is so equipped. The passenger side under seat air bag electrical connector contacts are a common problem area. So disconnect the battery & leave a door open, or turn a light on for a bit, to discharge any remaining stored electrical system charge, Before disconnecting the air bag electrical connector to inspect its pins, sockets & wiring for looseness, corrosion or damage. Also try cycling the air bag deactivation switch off & on a few times to clean its electrical contacts.
More thoughts for consideration, let us know what you find.
