Race Technology

Hi,

I have been wiring the resistors just near the sensor like this.

But over time i have seen a couple of the resistors break. I was wondering if i could just use one 1k resistor like this diagram i have draw up and also was wondering if i could just ground the sensors to the body as per the diagram rather then running back three wires to the DL1.

Not sure if it will work. Alternative i was thinking was to run the wires back but make up a small circuit board or something with a resistor for each sensor on it or it there already one made

You will need one resistor per analog input. The location of the resistor shouldn't be that important.

The way you've drawn your circuit, all of the analog inputs will be shorted together.

Thankyou. Was thinking this might work but looks not to.

How do people overcome the issue with resistors breaking, do you mount them on a board close to the dl1 or is everyone mounting them near the sensor?

I put a few layers of heat shrink over them and locate them where they won't see the full heat of the engine bay. Seams to work fine.
