1966 M20E Shunt amp/mv value

[MMsuper21]

Greetings,

does anybody know the shunt specs for a 66 M20E. I looked through the forum but only found values for 67 and up. Of course the 66 its own electrical diagram with hieroglyphic part numbers:

#105918 Figure 50F

I know we can measure it, however I am just filling out the order form for the CGR 30c

Thanks

Mine is marked as 50MV, I assume that is 50MV per amp.  It is stamped on the side of the shunt.

I will take a picture and post, as I happen to have the airplane apart at the moment.  It’s a 1965 M20C but I bet it’s the same shunt used in everyone’s plane, likely a stock part especially if you have the Garwin six-pack cluster gauges.
