Folks, This is my first real post here. Been lurking and taking it all in. Great people! Searched but couldnt find anything to help me out here. I looked through the Manual quickly but thought I would ask. I just changed the oil in my XB9R. Everything went fine but when I went to start the bike I noticed the oil pressure light didnt turn on. I have been riding and havent noticed it not lighting before starting before so not sure how long it's been like this. It was late but I started to debug it a little. First I just disconnected the wire to the sender and thought for sure that the light would come on but it didnt. I'm not an electrical guy so I just thought maybe the light worked differently so I jumped the wire to the frame and sure enough it came on. Does it sound like the sender is bad? If so how tough is it to replace and will I need the took mentioned in the manual? Thanks in advance. -Bob | ||

Does it sound like the sender is bad? That's what it sounds like to me. If so how tough is it to replace and will I need the took mentioned in the manual? Not sure how difficult it is. I don't have my bool with me so I don't know what took you're talking about.  Too bad spell check doesn't catch typos! No kidding though, I'm not sure about the tool. Should be pretty simple to replace the sender though. | ||

Glitch, My spelling isnt the best(guess I depend on spell checker to much)  . It sucks when you fat finger the keyboard and it actually spells a word and the spell checker doesnt pick it up. Glad you knew what I meant. Do you know if the light should come on when the wire is disconnected? I read in the archives somewhere that it should. I have an old Alfa Romeo that does the same thing. If I disconnect the wire to the sender it doesnt come on, but when grounded it does. Thanks -Bob | ||

Hi Got the same prob' on me 03 XB9's Oil light does not always come on. So far it's done it 3 times, Comes on after you turn it over and shut it done again, it's back on. I wonder if this will be an on going problem. Any one else have this happen ? | ||

I've not had the problem, and I'm not sure of the answer. Hopefully someone will chime in here, that's less of a smart •••, and more smart than I.  | ||

inexpensive, and very simple. single terminal pressure sender, grounds to case when pressure is less than 5 psi. OEM number 26554-77A, as used on ironhead sportster. NAPA- Echlin part #OP6613 Cole Hersee part # 8609. they are worth about 4 bucks retail. | ||

Fullpower, Thanks for the part numbers. I'll give that a shot and see how it goes. -Bob | ||

Fullpower, One more quick question on this subject. I am going to get a new sender but I'm curious about one thing. I went out yesterday and the light came on as normal. Started the bike and as expected the light went right off. Didn't let the bike run long at all. Turn the key back on and sure enough no light. Wait a couple hours and turn the key on and it works as it should. Is it possible that pressure is holding in the system behind the check valve? Like I said I'm just curious, the service manual doesnt really explain this. Thanks -Bob | ||

sounds like either a sticky switch contact, or (this is really reaching) cold thick oil pressurizing the filter canister, temporarily holding sufficient pressure to keep switch "OFF" after a minute or so the pressure bleads off, switch activates. i would consider replacing the sending unit. earlier this summer i was running my sportster HARD. up a long straight grade, ran it up to 6500 in 4th, as soon as i let clutch out in fifth, cranked throttle wide, looked down and saw the oilpressure lamp illuminate ( at 120+ MPH) i grabbed the clutch, flicked the kill switch, coasted ALL THE WAY home right into my garage. i had shredded the oil pump drive gear, packed the oil pump with schrapnel. put in new gear, new oil pump, the engine LIVES. it actually survived a full throttle fifth gear loss of oil pressure. hard to believe. if the oil pressure lamp had been inoperative i would have absolutely destroyed an 89 inch S&S stroker motor. i have no doubt that 3 dollar aftermarket oil pressure sender saved a 5000 dollar engine. | ||

Thanks for the info! I'm with you. Going to replace it for sure tomorrow. Just seemed a little strange the way it was inop. I am sorta used to seeing that pressure light on telling me all is well before starting especially with my 73 FLH I just finished restoring. I don't work on to many newer bikes. I agree its a lot cheaper to replace it! Thanks again. |
