Troubleshooting (General)
In many cases where the cause may be listed as a cable or wire disconnected but also includes loose or broken.
AllRibboncableshaveanextrareceptaclenearoneendformeasuringsignalsonthecable.
A number of the measurements will require probing of some small connectors or measuring signal on ribbon cables.
Forprobingthesmallconnectors,standardmeterprobesareusuallytoobig.Wesuggestmakingacoupleprobes
usingsteelwire.Copperbusswireisn’tstiffenough.Apaperclipisalittletoobig.Oneideaistakeasocketfrom
