Hello,
I'm fighting with VDO temperature gauges for my old Valmet 862. (I have 2 gauges, 1 spare, both show same)
Sender:
I have following sender: https://vdo-webshop.nl/en/temperatu...emperature-sender-120c-m14-4103590693433.html
After resistance measuring for it, seems +/- correct, but when connected to gauge, it shows 80C degree cold engine, when warms up ~120.
Tested without putting in engine manually 24V supply etc.
Gauge:
I asked in electronics forums, they told that gauge is faulty and possibly need to replace resistor/something, but no clear answer there. Will measure all resistor in it tomorrow.
VDO gauge part number is: 310 475/3 10 24V 8.80 OR 310040002
1) I'm just wondering how this works.
2) I believe I can't just grab another 24V gauge from different manufacturer, cause resistance will not be correct and wrong readings will appear?
3) Grab another gauge and "calibrate" it somehow by adding additional resistors to show 40-120degree range?
Thank you!
