Parmak Frequently Asked Questions

9.Q.Why is a good ground important?

A.Regardless of make or model of fence charger, it is essential the fence charger be grounded properly.

Think of an electric fence as an independent electrical circuit. In order for the circuit to operate properly, it must be grounded. AC models operated on poor ground will continuously blow fuses and will eventually be damaged by a poor ground. Battery models operated on a poor ground will have little or no shock on the fence. It is recommended that the higher performance, low impedance models Mag12 U.O., Mag12-SP, M8, S.E.5, and RM-1 have three ground rods to insure proper ground.

Remember, poor ground costs you. Refer to the fence charger Owner`s Manual for detailed grounding instructions.

10.Q.Can Parmak fence charger chargers be used on high tensile multiple wire fences?

A.Yes. The Parmak models Mag-12-U.O., Mag-12-SP, M8, S.E.5, and RM-1 are all high performance, low impedance fence charger chargers specifically designed to use on high tensile fences.The model RM-1 is the most powerful model, capable of charging many milesof fence. All five models are equipped with Parmak`s exclusive performance meter which tells the customer the exact condition of fence. SPECIAL NOTE: For those customers using Poly wire or Poly tape, any of the Parmak low impedance models can be used with this type of fence without difficulty.

18.Q.My solar fence charger manual states that my fence charger was shipped with a fully charged battery but it also says that I should let it charge for 5 days in the sun before use. Why?

A.The batteries in all Parmak solar fence chargers are fully charged before they leave the factory; however, sometimes the units are stored at you local dealer’s warehouse.  Depending on the length of storage, the battery may become discharged. This is why we recommend letting the solar panel recharge the battery in the sun for 5 sunny days prior to using the fence charger. Be sure that the fence charger is turned OFF while recharging the battery.

You can open the battery lid and check the date stamp locatedon the top of the battery (shown in month/year). This will let you know when the battery was manufactured and when the battery was last charged at the factory. If the battery is older than six months, you should recharge the battery prior to first use.

Start with the fence charger. Remove the battery case lid (

The #902 - 12 volt battery should read 12 volts or higher for proper operation. If the battery is below these voltages, your battery will need to be recharged by either the solar panel or an external taper charger (#951 or #952) or if the battery is more than three years old, replace it with a new battery (#901 or #902). If the battery voltage is OK,then check output voltage of the fence charger. If you are getting a good charge from the fence charger, that means the problem is somewhere in either the ground or thefence.

c. How do I test the solar panel on my fence charger?
The solar panel on both our 6-volt and 12-volt fence chargers very rarely fail unless there is physical damage to the panel. If the glass or the plastic frame is damaged, the panel may continue to operate until moisture gets under the glass. When this happens, the solar panel will begin to deteriorate and it will no longer be able to charge the battery. At that point the solar panel will need to be replaced (
replacement parts: 6v #920, 12v #960)

You can test your solar panel with the battery disconnected. To do so, aim the solar panel directly at the sun. Using your standard voltmeter connected to the battery cable connectors coming from the solar panel. You should get between 8 - 10 volts for the 6 volt solar panel and between 13 and 18 volts for the 12 volt solar panel. If you do not get the correct voltage, the solar panel should be replaced.
