83brat Posted March 23, 2013 Share Posted March 23, 2013 Following a motor rebuild from a local shop, my temp and oil press. gauges do not work. The manual has me feeling a little stupid, so please advise if you will. The manual refers to temp sender, Thermosensor for the carb, and Temperature Sensor. I believe I have a Hitachi carb, and only two temps senders: 1 in the intake manifold, and one in the radiator. Each one has a single wire connected to it. I've pulled the dash and can't trace continuity from the grn/blu wire to either connected to the senders (it actually has continuity to ground. This is the wire in the large round 12-14 pin connector). Resistance to ground is infinite on both senders? My ECM and carb cannot be using feedback with only a single wire correct??? Is the wrong temp sender currently installed? Thought the one in the radiator should be a thermo-switch providing power to fans? Also. I wan't to simply go mechanical temp gauge, but CANNOT find one to fit a 12mm hole??? Thanks in advance for your help.... Quote Link to comment Share on other sites More sharing options...
