Auto Electrical Problem

[handdrummer]

A new alternator & battery was recently installed and afterward the check engine oil light stays on. The oil is full.
Any relation between alternator installation and light being on?

Thanks gents.

What car is it. Older cars it may just be a wire off, more modern cars with some form of ECU may need to have a fault cleared using a test book / laptop.

It's way older than that. 1984 Mercedes sedan 190E. A wire off sounds reasonable. I'll have it checked. Thanks.

To answer your question: no, it should not have anything to do with alternator. Usually there is a small pressure switch that closes when there is no oil pressure, and opens therefore the light off, when pressure builds up. maybe the switch is bad.

Could be faulty low oil pressure gauge or oil pump best to get checked out and you will need merc parts best of luck.

Thanks guys. For the moment the problem has solved itself. The light is off. Oh yes, those merc parts; there in the price range of treatment at Bangkok Hospital.
