I need some help in fixing my Temp Gauge. Since I bought my "D" 8 months ago I have not had a working temp gauge. We have disassembled the binnacle and changed gauges but this did not fix the proplem. On the main wiring curcuit on page M:18:23 the diagram shows the gauge being hooked up to item #246. Can anyone tell me what that is? Is it the alternator? Any suggestions to help me get this gauge up and working would be appreciated. Bill (11096)
