Super Beetle Mexico built vs Empi Sender differences. Testing done with cal. Gauge 7.5 reg.

I do not recommend modifying the aftermarket vibrator/regulator nor calibrating the gauge to work with the 7.5... See my videos about Buck regulators and soon I will be doing a video on a simple regulator to resolve the aftermarket gauge issue.
Video shows the differences between the Super Beetle Mexico built and Empi Senders.
The Testing performed is with an aftermarket gauge that has been calibrated to the 7.5v regulator/stabilizer.
