		How the Positive Ion Control System Works
		The PIC system uses an internal circuit that passes
	Ion	the voltage through the drive train of the Magnum to the
	Ion	shaft. The shaft contacts the cable by means of a ball
	Control	shaft. The shaft contacts the cable by means of a ball
	Control	bearing, spring and, lastly, a one direction button head
		screw. Care must be taken to ensure contact between
	Theory	the cable and the screw when replacing the cable.

		The Positive Ion Control system applies a fixed 0.6
		volts on the trolling cable at all times.

Measuring the Natural Electrolysis and PIC Voltage on Your Boat

A voltmeter with a scale of zero to one volt will measure the natural electrolysis. Place the ground lead of the meter on the motor or the battery ground. Place the positive lead on the stainless steel downrigger cable while it is in the water. The downrigger must be unplugged. The voltage you measure on the volt meter is your boat's natural electrolysis voltage. Use the same set up to measure the PIC voltage; just plug in the Magnum and adjust the PIC voltage desired.

Using Positive Ion Control

Positive Ion Control is very effective when trolling. The zone of attraction created at the downrigger wire will attract the fish. It is best to use a short drop back between the downrigger release and the lure. Drop backs of 10 to 20 ft. are typical. A drop back of 50 to 100 ft. will entirely negate the effects of the PIC circuit.

Maintaining Your Downrigger

Periodically, lightly grease the thrust bearing and bearing race found behind the clutch knob. Replace the cable at least every two years.

There are no user serviceable parts internal to the Magnum. Your warranty will be void if opened by anyone other than an authorized or factory service center. For repairs or servicing your downrigger re- fer to the Warranty Information section of this book- let.
