Ok, here's my dilema and question.
I have one of these VDO Head Temp Sensors and 6 leads. I want to be able to monitor each head's temp. I'm running webers and thought this would be a handy thing to help figure out if/which one were running too lean. They work off impedance or resistance, don't have the part here or I'd go into detail. What kind of switch, etc. would work without giving unreliable results? ( I don't want 6 guages) Any thoughts, comments, experience? |

BTW, the thermocouple senders (that's what those are, thermocouples) send a voltage. They do not change resistance with temperature, they actually put out a voltage difference depending on the temperature of the sender. I hear that it is very very critical to have zero (or as close as is practical) resistance in the wiring from the gauge to the sender. That's supposedly why VDO tells you not to shorten those wires.
