CB500/550 / Oil Pressure Switch and light - much confusion on my part!!
« on: January 25, 2016, 12:00:31 PM »Just rebuilding my 500 K0 1971 (USA model)and have come across an electrical problem.
On the bike currently there is a brass small pipe coming off the top of the oil pump which is connected eventually in to a small diameter plastic tube that leads along with two wires to the front of the bike.
The tube and the wires have been snipped off by someone so I am unclear what happens here. I assume the small pipe went in to a pressure switch somehwhere but I can't see a switch anywhere. I further assume the two wires went originally to the oil pressure light on the "idiot" display.
I am now however even further confused as I can't see anything resembling this on the Honda parts list, what I do see however is an oil pressure switch mounted on the oil pump where my current small bore brass pipe connection goes.
As always I am sure there is a simple explanation and hope a fellow owner can shed some light on what I need to do. Obviously haveing a functional oil pressure light is kind of important!!!!
Look forward to the replies
