Re: Console temp gauge
The low fuel module is a comparator circuit of some sort. Essentially it says when the sender reading is below a certain level, light the bulb. Now days, to build something like that could be done with an op-amp or a comparitor, a transistor, and about 4 resistors. Back then it was probably a flip-flop circuit made of two transistors and a few resistors.
