[AReU] Limited Inquiry

[Robert Haynes]

I need to know how to a simple circuit to turn on an LED when I reach the upper and lower limits of motor rotation on my screwdriver antenna.
I assume a LED would be activated by increased amps being drawn.
I bought mine from Larry's Antennas and have installed it on my motor home.
I e-mailed the manufacturer, and Larry says he does not know of a commercially made limit indicator.
Since I cannot hear the screwdriver motor running from inside my RV, I need an indicator.
I considered using my ampmeter, but was not sure how easy it would be for me to keep an eye on my ampmeter and watch my SWR meter at the same time.
If someone could tell me how to build a LED limit indicator, that would be very helpful.

My loop antenna is over 900 feet long.  Hope to attach the ladder line and fire it up soon.
