WTK Resistance value

[pacho]

Hi folks, does anybody know the temperature unit resistance values?
I'm asking because I measured two temperature units (NOS) and found a difference between my obtained values and the ones in the 'Troubleshooting for Military Standard Instruments' manual.

Thanks in advance

Pacho, First you must tell us what part number gage and sender you have!

Hi Wesk,
thanks for replying.
I bought the temperature sender unit on eBay. https://www.ebay.com/itm/326396415998. you can see.
I measured its resistance with my multimeter and compared it with the document. Then, I heated water on my stove and measured the resistance at different temperatures. My values are different from what the document shows.
Then, I measured the resistance of the gauge coils. I think my readings are correct, but I don't know the exact reference values. Do you happen to know what they should be?
Thanks and best regards.
It's a pleasure to share experiences and learn together with people who share the same hobby!

Do not overlook your M38A1 parts manual. Make sure both the gage and the sender are correct as listed for your M38A1. If they are not then odds are the TB 9-2300-228-20 and TB/ORD 479 may not apply to them. Also it helps to always post the part numbers of components you are trying to troubleshoot.
