How the Positive Ion Control System Works 
 
The PIC system uses an internal circuit that passes 
the voltage through the drive train of the Magnum to the 
shaft. The shaft contacts the cable by means of a ball 
bearing, spring and, lastly, a one direction button head 
screw. Care must be taken to ensure contact between 
the cable and the screw when replacing the cable.  
When using coated cable, 3-4 ft of coating must be 
striped when terminating the cable to reel.  Take care in 
ensuring that the striped portion is in contact with the 
button head screw. 
 
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.
