oil light

Presently working on a Hyster 90 forklift, Model#H90XMS; Serial#K005V3382Z and the oil light flashes on and off continuosly. There is plenty of oil in the motor and the motor runs fine. Any suggestions on where to look first?

I know it seems like a waste but check the oil pressure itself first, often you can find the O/P sensor and hook a gauge up quicker and easier then cleaning all of the grounds and if there is a legitimate O/P issue it shortens troubleshooting time and keeps you from running a motor with low oil pressure any longer then you have to; for me it is 5-10 minutes well spent.

If after all grounds are cleaned and reinstalled, where is the pressure switch located? Keep in mind this machine has a cab installed on it and makes it difficult to see inside the engine campartment.

Remove all of the grounds form the engine, trans, and chassis, clean and reinstall them. This has always resolved 90% of my flickering dash light issues and it doesnt cost any money in parts. If that doesnt work change the pressure switch.
