ABS light went off the other day, should I be worried?

[Anton CH.]

I came to a complete stop (dry weather, smooth stop-no lockups) and the yellow light just went on and stayed on. Went away after an engine restart. Debating whether I should test the abs system when the weather turns sour...

on a 1992 car as u have, the abs system tends to play up, depending on climate, like here in the uk the sensors get all crudded up or break and the notches in the disks that the sensors read become to badly corroded for the sensors to tell whats going on

so could be many things, loose wire, corroded sensors...get under it and have a look
