Mark, The sending unit is a pressure regulated resistor and will read high? with on ignition. When you have engine run it will read the correct pressure if the sending unit is the correct one.

> The last time I ran my engine prior to making a new starter mount / housing, my oil pressure gauge was working perfect. To remove the old starter mount / housing, I also had to remove the oil sending unit. Therefor, I disconnected the wire at the sender. I noticed in the mean time as I was working on my plane, if I turned the ignition to on, the oil pressure gauge would max out. I think this is normal with the sender disconnected. Anyway, I reinstalled the sender after I made the new mount / housing. I then went to attach the wire and twisted the post right off. Bummer.... I ordered a new $35 sender and it arrived today. I installed it, attached the gauge wire, turned the ignition to on and the gauge immediately maxed out. What's up with that. Is it possible the new sender is bad? Is there a way to test the sender? > > Mark Jones (N886MJ) > Wales, WI USA > E-mail me at flyk...@wi.rr.com > Visit my KR-2S CorvAIRCRAFT web site at > http://mywebpage.netscape.com/n886mj/homepage.html > > _______________________________________ > to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net > please see other KRnet info at http://www.krnet.org/info.html
