\u2013 Problem<\/strong><\/p>\n

Tech II clone not boot up (not turn on)<\/p>\n

\u2013 Reason<\/strong><\/p>\n

The issue usually results from the DC to DC converter<\/p>\n

This converter is a common internal component for the device GM TECH II<\/a><\/p>\n

originally these come equipped with the \u201cMeanwell SKE10A-05VT\u201d and \u201cBTCPower 4BE-01T-02\u201d<\/p>\n

you cannot longer purchase these items because they are not being manufactured anymore<\/p>\n

You actually can find the \u201cMeanwell SKE10A-05\u201d but missing the \u201cVT\u201d and also missing 1 pin for the soldering points.<\/p>\n

BEWARE this model dc to dc converter WILL NOT WORK<\/p>\n

It may help you power on your device, but the power button among other programming features won\u2019t work.<\/p>\n

\u2013 Solution worked!<\/p>\n

To replace DC to DC converter can avoid unpleasant surprises.<\/p>\n

REC10-1205S\/H2\/M has a 6 pin connections, \u201cMeanwell SKE10A-05VT\u201d and \u201cBTCPower 4BE-01T-02\u201d have a 5 pin connections, is it not a problem when you change the component.<\/p>\n

So, sort this out.<\/p>\n

This list is for a DC to DC converter with the following specifications:<\/p>\n

Input: 9~18VDC
\nOutput: 5VDC 2.0A<\/p>\n

\u2013 The important note: Tech2 not boot up when the car starts<\/p>\n

So, how to fix a reboot Tech 2 when starting the car? The square dedicated native voltage Stabilizer, black spots, this is how it is better to feed on, immediately giving to drink block, then the main Board gently giving to drink lagged behind in her legs. By means of wooden toothpicks carefully remove the solder prepared under us new voltage regulator (mornsun VRB1205LD-15W DIP).<\/p>\n
