Small separate single blue resistor?

[cactusman]

Reviewing my leftovers and going thru plans to mop up issues, I found a single small blue resistor in my avionics hardware kit box and don't have any clue what/why/where/etc.

Not any part of the master/engine diode cables - those are both hooked up, just one by itself.

Any ideas?

Like the one below but it has 5 bands and all are red.

Thanks 4 any help.

If I remember correctly this resistor came with one of the Dynon boxes. There is nothing specific about it for the 12 and it does not get used.
