David, Check to be certain the resistor in the positive battery lead is intact. Remove the connector from the RF board and the connector from the battery terminal. Read the resistance between the red wire at the connector and the terminal that connects to the battery. You should find a low resistance - note what it is, then switch the DMM leads and measure again. You should find 6.2 ohms with the leads in one direction and in the other direction, you may measure less than 6.2 ohms depending on your meter and the exact forward voltage of the diode. If you find a high reading in one direction, the 6.2 ohm 2 watt resistor in the battery option wire (under the heat shrink) has opened - if that is the case, the battery will not be charged from the K2 power supply connection.
If the resistance is correct in both directions, then you may conclude that you have a defective battery. 73, Don W3FPR On 12/15/2011 8:17 PM, [email protected] wrote: > ---------- Forwarded Message ---------- > From: "[email protected]"<[email protected]> > To: [email protected] > Subject: K2 Battery charging Problem > Date: Thu, 15 Dec 2011 21:39:30 GMT > > Recently purchased and installed a new 2.9 amp battery in my K2.
