M1009 Brake & back up light help

[tommyd]

Hello folks,
I just found this forum and registered. I recently purchased a 85 M1009. It actually runs pretty good and now has 32K miles.

I have many questions, but need help resolving this issue first. Today I was pulled over due to no brake lights. I was actually coming back from the parts store with a new plug for trailer lights. To be honest, I do not think they ever worked. Well I had this vehicle for a whole two weeks.

I know I have no power to the rear brake/back up. BO service lights are operational, but off, the rest of the normal lights work. I have no manual and checked the fuses. Does anyone know where this fuse may be? I am hoping for a fuse issue. That would be a blessing. If not, does anyone know where this wire starts, so I can check power there and trace back? Any additional information would be greatly appreciated. Thank you in advance.

Semper fi,
Tommy D

No more no manual excuses soldier.

You should take a close look at the blackout switches after the fuses. The lights are controlled by them and if they are not working correctly you could have the symptoms you describe.

The blackout switch on the right has to be on the up position in order for the brake and headlights to work. Read the TM 9-2320-289-10 Operators Manual for instructions on the basic operations of the truck.

And welcome to the OD madness

I sure need to redo all those photos. At the time I thought they looked good. LOL


And that fuse box map has an error on it. I'll post the corrected one later today when I get to my laptop.

I had some light issues when I bought my first M1009 and what happened was the socket of the right turn signal was not grounded check the socket itself. mistaken1 is pointing your in the rite direction. The best route is to listen to warthog. When in doubt, whip it out. TM that is
Oh just thought of a possible solution the boys in the motor pool tear up the wiring under the dash to attempt to fix glow plug issues check and see if they managed to disconnect the pressure switch to the brake pedal that could be your culprit
Good luck and welcome.

Thank warthog.

All I am doing is reposting his pictures after his original thread where he took the time to disassemble the truck, take the pictures, label the pictures and post the pictures seemed to disappear. At most I am but a humble student dutifully regurgitating the notes that I took from his lecture.

If you want to repair your truck warthog has the answers. But like any other good apprenticeship program you have got to do the work, his brain and your brawn will get it done.
