I currently own a 2006 Hummer H1 Alhpa and I am having Electrical Problems.

1. When I start the engine all of the LED lights on the dashboard turn on
and the Electrical output is 10V.

2. I have found out that when I take out the No.9 redwire hooked up to the
Oil Pressure & Temperature Panel, the output goes up to 14V and all
of the Led lights turn off but if the red wire is unhooked the Led lights
on the Oil Pressure & Temperature Panel will not turn on.

I believe there is some other problem causing this matter, But I do not
have any Electrical Diagrams or manuals to follow.

I suggest purchasing the H1SI its the H1 Service Information.
Shows you everything about your H1 and gives you diagnosis information for various problems...

A Diagnostic tool will not help and electrical short..It only downloads what the PCM has stored pertaining to emission codes and malfuntions, and stuff like that..Se my post on your other thread..

its not a diagnostic tool its a workshop manual/spare parts manual and such... and in some cases it gives you various problem examples and gives you hints on what might be wrong etc etc etc...

Oh I see...My mistake...But still the problem he has sounds like a shorted circuit in his gauges and the manual you suggest may help with the the wiring diagrams to maybe help isolate about where the problem could be.

yea its all good... and yea I am not sure what could be wrong but I just purchased the workshop manual and briefly scanned it and it looked very useful... even though I likely wont be doing my own mechanic work anytime soon but always good to have just incase especially if you need to do some in the field repairs

A gentleman sent me some info related to the Transmission Temperature/Engine Oil Module and in this info it mentions that
there is an internal timer which supplies a ground to all the LEDS on the board. It would be very helpful if someone could
mail me a electric diagram for the wires surrounding this area. Sorry for the Trouble.

i'd send you diagrams but mine is for a 1998 and the wiring and engine is completly different in a 2006 alpha because its the 6.6L duramax diesel not the 6.5l turbo.
but you might have some luck here:
