Hello everyone I tried to move the o/d button per an old thread, however it is not working as DanMan found out.

Well I cut the plug and tried to wire it up to the gear shifter. When I pushed the gear shifter button something went click....it shifted out of o/d but it also sent the voltage gauge to zero along with the temp gauge to all the way hot.

I now have no wait to start light or water in fuel light either. Can someone offer some help?

I looked in the sticky but didn't find the info to this problem

The old thread is this one listed below.

Thanks, Tony

 

I found the problem with the gauges....a blown fuse. I swear I did look but didn't see the one for the gauges!

Well folks I've been at this for awhile now. Here is the results....I can get the o/d gear button to take the tranny out of o/d wired up two different ways! The problem is I have to hold the button in or it will go back into o/d/

Any ideas?

 

Have you taken a look at this thread yet?, https://www.dieseltruckresource.com/....html?t=173561 , it gives you pictures on the install. Here's a quick excerpt from the article about how to wire the shifter up:

"To connect the new OD shifter switch, find, cut and connect the new OD switch wires to the following wires from the OEM OD switch plug:

- 18ga Black = One side of the OD switch
- 20ga Orange w/white tracer = The other side of the OD switch.

NOTES:
1- You can connect the new OD switch in parallel with the OD switch and have both if you like.
2 - The remaining two wires are for the light that comes on when you work the switch. The new column shifter does not include a light. Sorry. Perhaps you can build it into a new custom information center."

If you follow the directions in that thread to a "T" than you shouldn't have any problems with it functioning when your finished. I did everything exactly as it was said and mine has been working great for more than a year. Push the button and the O/D is locked out, and the light comes on to signal that it's locked out.

 

I have looked at that thread....my pc must not be pulling up the pic's! I have got it hooked up where it works, but I have to keep the button held in.

Thanks, Tony

 

Hmm, than if it's hooked up exactly as it should be, but it's still not functioning correctly, than you may have problems else where. Good luck with this.

 

Yeah maybe this is one mod I should've left alone!

Thanks

 

Maybe a bad button. You said it will work if held in, It may not be "breaking" over. Hook up an Ohm meter to the button and see if it will open and close the circut.

The OD button on a '91.5 works differently than on a '92 or '93 truck.

How is your wiring done?

The button on the shift lever should be wired to the yellow/black and yellow/dark blue wires. Leave the orange/yellow wire and the dark blue wire on the old switch for the indicator light.

It sounds to me as if you have the dark blue wired into the new switch somehow?

 

Thanks guys for all the help I'll get back on it this afternoon, Tony

 

Yah, it sounds like you are grounding the dark blue when you push the button. It supplies power for the pilot light and is hot when the key is on, the orange/yellow wire supplies ground and turns on the pilot light when you have OD locked out. Put those two wires back on the old switch and it will still work as a pilot light. As an added bonus, if you connect the other two wires to the shift lever, the new button should work.

 

Sounds like when you were pulling up your wires or extending them to the shifter, You may have a barespot and its grounding out,

 

Well I did this....the tranny will kick out of o/d still only as long as I have the button pressed in. As soon as I release the button it shifts back into o/d.

I'm thinking I have a bad shifter?

 

I hooked up an ohm meter, but that doesn't mean anything....I'm clueless with wiring. The meter shows nothing until I press the button, then it will show some numbers....only while the button is still press in.

I didn't think something seemingly so simple was going to turn into this kind of headache!

 

So if you press the button the meter will move from OL to 0.1 OHM's? Or it will only read if you are still holding the button in and when you let go of the button it will go back to OL? If that's the case then I think you have found your problem.
