Checked with volt meter at battery with engine running and when a/c is engaged voltage is dropping from 14 to 11 volts. Turn a/c off and it is back to 14 volts. Turn lights, wiper, and heater on at same time and no voltage drop. Only when a/c is turned on. When this problem first started the magnetic a/c clutch was engaging and disengaging in rapid succesion. I wiggled the wiring to the magnetic clutch and it stopped disengaging and stayed engaged but the voltage drop problem appeared. A/C still gets cold even with voltage drop but I am afraid to use a/c for fear of draining my battery. Please advise. Thanks!
