oil pressure switch

Haven't seen anything on this but, I am guessing there is power to the oil pressure switch anytime the ignition switch is on. When the engine is running the oil pressure breaks the circuit and the light goes off. I have oil pressure, before I change pressure switch, I changed oil about 150 mi ago used fram oil filter. I just read a post by Old Dog he mentioned Fram oil filters, but didn't elaborate, what can anybody tell me. Thanks

What went wrong on my 03 was I got lucky so to speak... I was going to an air show to take some pics. and stopped by the Kaw. shop for something, when I started the bike the oil pressure light stayed on so I gave it a bit of throttle and still the light stayed on, I shut it down and got the mechanic, he said it was more than likely the switch, he removed it and got another, put it on and still no pressure, he thought he may have picked the one up he took off, so he put the one left on, no pressure, he then removed the switch and started the engine, no oil came out, so I did not have any oil pressure...
He went in on the right side and moved the water pump/oil pump chain back and forth and the darn thing started working... We think that it could have been a small piece of card board from the Fram filter in the pressure relief valve (ball & spring)... Everything is just guesstimation...
Have a good one...Old Dog...

Kind of hard to fire someone that was never hired. Double post means more visitors, after all didn't you visit both post. Ha! Actually I tried to delete one but when I went to edit I couldn't find delete. Someday maybe I will become site literate !

Maybe I don't have oil pressure, I removed the sending unit today started the engine and no oil came out. I also checked the current with a test light at the sending unit and at the plastic connector in the head light using the same ground for both checks. The end that goes to the sending unit ( disconnected from sending unit to check) has less power !!

I think you are right, I don't believe you have any oil pressure...
You might try what the Kaw. mechanic did...

I really was not looking forward to that. It seems like a lot of work for guess work but at this point I see no other options. Thanks!

Oh, do you know what it takes to actually get to the pump, you are talkin nothin here, as compared... I think... I guess I would burp it, belch it, swap filters, turn it upside down and shake it, whatever before I tried to get to the oil pump... If I remember right...
Someone correct me if I'm wrong...

What about putting a vacuum on the hole? Whatever is stuck couldn't have gone far or you'd be seeing oil.

BTW, at least with the cartridge filters for my 77 Mercedes Diesel, the only good Fram filters are made in Turkey. The others are made with cotton gin waste... aka the crap from off the floor. People have found twigs, rocks, you name it inside those things. Bosch is only a few more dollars.

If it ain't broke... well I'm sure I can find something that is
