Hi, i've just got hold of an ET4 125 and the oil light is illuminated when the key is switched to "on". I checked the dipstick, and the oil was low, so I topped it up, but the light still comes on... Also checked the dipstick at the rear of the engine, thinking maybe the light applies to both, but that is fine too. I'm now leaning towards a faulty oil light/connection, but thought it was worth posting up here to see if any of you guys have a suggestion at all?
Cheers!
