My chargers no longer come on or blink? The most common reason is a blown fuse. It is all too easy to accidentally plug in a drill or electric power tool into a charge strip and overload the circuit. Just replace the fuse with a common 1 Amp fast blow 1-1/4 inch fuse. (Available at Radio Shack and most hardware stores) If this does not fix the problem or if the fuse continues to blow without an overload then return the unit for service.
My chargers get warm or their lights stay on, no trickle? Test the charger with by plugging in a 60 to 100 watt light bulb. Unplug the unit from the wall for several seconds. It should now be in the trickle mode and you should observe the bulb blinking from full brightness to full dark. If you see bright to dim or full brightness continuously then your unit should be returned for service.
My chargers do not maintain a charge when in trickle mode? The Auto-Trickle Adapter has been used over the past few years with great success with hundreds of chargers used in the Radio-Control Market. To date we only are aware of problems with old Kraft radio chargers and a newer HOBICO Multi- Charger draining the pack during the off portions of trickle. The solution is to insert a commonly available diode in the plus lead going to each battery pack that is affected. The diode may be obtained at any electronic supply outlet such as Radio Shack. {Wire as shown:)
Please note that the diode has a band that denotes a polarity. The side that the banded end is soldered to must be exactly as shown and go towards the battery pack. Wrap the diode with electrical tape when done soldering into the + (Red) wire.
