2008 Kubota BX23 engine in BX25 Temp Gauge Stuck pinned HOT

Since you seem to be electrically oriented and you (or someone) mentioned LEDs, could you use the existing gauge and embed a few leds into it? Maybe three to six LEDs and set them off at different temperatures and color code them?

Basically a digital/analog type of gauge. I think I have seen some on modern car dashes.

Yes I thought of that and might end up doing that. The reason is mounting a clumsy gauge on a tractor with no logical place that often gets rained on is a problem. I thought of just doing the circuit I already showed and by adding a simple comparator like an LM393 and 3 LEDS for maybe Blue or white =cold, Green = in safe range and Red for too hot. I could just put them inside the existing dash which is waterproof and located in front of the driver. Not a bad method. thanks... It eliminates the mechanical gauge mounting issues which is messy. Its all I need to know anyway. I could even but a small buzzer alongside the red LED as an audible Hot warning. This might just be the best solution. I could just tap the existing temperature sensor voltage entering the dash and calibrate my LEDs for appropriate voltages for cold, normal and hot.

curious, found these, Amazon probably have them as well...

$5 CDN...... 1/8" NPT. To me it's the simplest solution, leaves original sensor in the block, YOUR 'upgrade' is 100% independent of the original wiring and such.

just checked amazon.ca, 2x the price to $54 !! for same piece !!!
