Guest 1930 Posted August 15, 2009 Share Posted August 15, 2009 Can someone tell me if a 6 volt sending unit will work with a 12 volt gauge? Gas sending unit I mean, the system is negative ground, thanks Link to comment Share on other sites More sharing options...

RickBrinker Posted August 16, 2009 Share Posted August 16, 2009 Sending unit doesn't care if 6vt or 12 vt Link to comment Share on other sites More sharing options...
Guest 1930 Posted August 16, 2009 Share Posted August 16, 2009 So a 12 volt gauge will read correctly what a 6 volt sending unit will tell it?? Sorry if the question seems obvious to you but it is not to me, seems to me that if I have one 12 volt wire on one end of gauge and a 6 volt wire coming from sending unit on other side of gauge they might not work well together. Maybe someone can explain to me why it would be perfectly fine to do this so that i understand better why it dosent care. Thanks Link to comment Share on other sites More sharing options...
JACK M Posted August 17, 2009 Share Posted August 17, 2009 The sender is just a reostat. The gauge is powered. The resistance value from the reostat has to match the gauge. So, some gauges will not work with some senders. Link to comment Share on other sites More sharing options...
Guest 1930 Posted August 17, 2009 Share Posted August 17, 2009 That is hwat I had thought, I asked the same question on another forum and I got mixed answers. Some say that the same as you have said here and some others say it will work and read correctly. I guess I dont feel like it is such a simple question any longer, thanks Link to comment Share on other sites More sharing options...
