Yes but only number on these is the number I listed wonder if there is a way to tell difference with a ohm meter ?

The number on the back is different than the sticker on the front I thought they were the same until I pulled box all way off but either way I can’t get it to cross with a merc 332 number got these same boxes on 5 motors one set i bought for a 200 just a few months ago others are on drag motors

I dont believe so as the only difference in the A14 and A12 is the A14 has a heavier duty Bias circuit whick helps in the Higher RPM ranges vs the A12. I looked an my spare Boxes today when testing and the Pt# is only on the package. The Boxes them self have the same type sticker as yours but no Pt#.

I’m shure there is a different resistance range between the two just need a know a12 and a14 to check the difference
