Demco stated that the pulsing that you've been experiencing with the Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor - Proportional # DM86VR when your turn signal is activated is normal and usually caused by the sensitivity being cranked up too high and near the max setting.

You can adjust the sensitivity of the inertia-sensing mercury switch with a knob on the front of the G-Force controller. Adjusting the sensitivity lets you decide how intense the change in momentum must be for the sensor to respond. Adjust it to fit your personal preference so that you can get a customized braking experience. Set the sensitivity low and the DUO will only respond when you forcibly step on your RV's brake pedal. Set the sensitivity high and it will respond when you merely tap your RV's brakes.

To fine-tune the sensitivity, first move the knob all the way to its most sensitive setting. From there, you can apply the coach brakes and gradually move the knob until you get the setting right where you want it. You only need to set the sensitivity upon initial setup.

If this does not solve your issue then please reply back and we can keep troubleshooting.
