ERROR FIXEDX - R-200KOhm to GND PIN 2 and 3 short is corect for charging APPROVED
CORRECTThe pin outs were correct. The description of which pins are shorted to get the phone into charge mode was also correctAPPROVED
ERROR FIXEDit"s 200k or 220kAPPROVED
INCORRECTin the corrected section the pins for charging are marked as corrected but the text and table are still wrong, see http://krhainos.tk/motoplug.jpg for detailsAPPROVED
CORRECTConfirmed via resistance testing and also via attempting charge a RAZR via a normal USB A - USB mini cable from a USB solar panel with negative results. Creating a cable from Motorolas original wall chargers USB mini connector and a regular USB A cable allows it to charge from a USB solar panel.APPROVED
CORRECTConfirmed working with 220k resistor. D- can be connected before or after the resistor without any negative effect.APPROVED
CORRECTI opened the AC charger while soldering a broken wire. I was able to verify the connections (pin1: +5VDC, pin4: GND ), and the value of the resistor (200K) between pin4 and pinX. After soldering the broken wire, I connected to the cell phone and started recharging without any problems. I also took some pics to save with the documentation.APPROVED
INCORRECTThe directions are mostly correct. I found that pin 3 did need to be connected to x and 2 and the wire absolutely needed to be continuous to both ends of the cable. You can see a picture of the completed circut on the breadboard I used at the link below. Ill probably solder it all into a compact cable. I tried to diagram it in text also, but I worry that it will get formated strange when I hit submit.

INCORRECTThe new moto chargers (p/n: SPN5185B) came with Moto Q/Q9/V195 have pin 2 and pin 3 shorted together, pin x and pin 5 has 200K Ohm resistor across. Pin 2 and pin x are **NOT** shorted.

2012-03-29 01:03:31rev. 15ERROR FIXEDMy car charger cable (MOT V3) has 200kOhm between X and pin 4 (GND). Pins 2 and 3 are connected to each other (bridged, not hooked to anything else) and pin 1 is hooked to +5V. Cover on mini-USB was openable. Best Regards from the Electronics Engineer.APPROVED

2012-12-14 18:20:23rev. 15CORRECTno errors in the discussion. I have a moto v197 and eventually worked out that 161K produced the required 1.16 volts to make charging start. A tenth of a volt either way and charging would not start. Thanks for the adventure and the solution to a most vexing problem. --ajoAPPROVED
2014-11-04 18:10:47rev. 18CORRECTAndre's solution worked on a razr2 v8. USB data pins shorted, and 165K resistor between pin X and Gnd APPROVED

2008-08-21 21:55:07rev. 4ButchThe RAZR V3 charge strategy didn't work with my MOTORIZR Z6tv so I took it upon myself to probe it out .
2008-09-09 14:48:13rev. 4Andre QuirionI've took 3h to figure out my wiring wasn't working as it should be... and this is the result of my "strugling"

2013-02-28 22:32:57rev. 17better clarify diagram, 2 - 3, and X to 4, but NOT X to 3 connected
