Blue Motor Transitor Coil and Tacho

[HXsman]

Hi All,

My van (HX) has a WB Blue motor. I recently put in the transistor coil as I was told this is required and was what the blue motors came with. My tacho works albeit it stops at 2,000 revs. Pretty sure it worked properly with the old oil filled coil there.

Any thoughts or recommendations ?

Am I using the right coil?, if not which would you recommend.
