If so there is an off position so you can sit in the dark with a door open There is a door position that turns light on when either door opens There is an on position so you can read a map without opening a door. The terminal (marked with red paint) on the far left should have power at all times. It should go to the bottom center terminal of the bulb. Is this what you called the middle cable? Yea, I took it off to examine further and it looks like the points are corroded. Also the left connection isn’t attached like ther other one. Should it be? I can solder it back Quote Link to comment
datzenmike Posted May 22 Report Share Posted May 22 Try working the switch back and forth a few dozen times to clean the contacts. 1 Quote Link to comment

Joecar Posted May 22 Author Report Share Posted May 22 Does the green ribbon cable not work cause of the dirt or corrosion on it? Quote Link to comment
datzenmike Posted May 22 Report Share Posted May 22 It's the contacts the switch arm rubs over. The arm itself may need a little WD-40 to loosen it up. The interior light swings down to act as a cargo lamp in the back. That's why the ribbon. 1 Quote Link to comment
Joecar Posted May 22 Author Report Share Posted May 22 I think the switch works now. I have the test light grounded to bolt on the chair and when the light switch is in the top position the test light lights up, but when I move it to the middle and down position it turns off 3 hours ago, datzenmike said: It's the contacts the switch arm rubs over.

datzenmike Posted May 22 Report Share Posted May 22 What does the interior lamp do now? Quote Link to comment
Joecar Posted May 22 Author Report Share Posted May 22 Is this supposed to be like this? Quote Link to comment

datzenmike Posted May 23 Report Share Posted May 23 All I have are schematics. Take the bulb out and test the center of the bulb socket for power. It should have power at all times. Be careful not to short it to the outer case that holds the bulb. The bulb is turned on by grounding the outer case of the bulb socket either by the door switches, the switch on the lamp or the room lamp timer under the seat. Quote Link to comment

Joecar Posted May 23 Author Report Share Posted May 23 Located it and it doesn’t look too good. Not sure if it got moisture in it cause this truck did have a few leaks Quote Link to comment
datzenmike Posted May 23 Report Share Posted May 23 There should be power to the center of the socket. Follow from the socket back. Looks like the Black/Yellow stripe wire going to that ribbon. Follow back checking every connection till you find where power is not getting through. First is the Black/Yellow where it joins the ribbon on the right. Quote Link to comment
Joecar Posted May 24 Author Report Share Posted May 24 Just found me a complete EFI for my truck off Facebook for $250. Can’t wait to put it back on my truck, current car drinks gas like crazy and idles above 1200 rpm Quote Link to comment
datzenmike Posted May 24 Report Share Posted May 24 Set right you should expect 18MPG 4x4 and 222wd. (more or less) Quote Link to comment

IZRL Posted May 24 Report Share Posted May 24 51 minutes ago, Joecar said: Do these truck sit at 1k rpm or a little less? i believe the book says 8-900 RPM. I have mine set at about 800. 900+ sounded too high to me. Anything under 800 was too low, and the engine starts running choppy. At least for my truck. 1 Quote Link to comment
Joecar Posted June 2 Author Report Share Posted June 2 My oil light came on while I’m as warming up my truck the other day. I start driving and it goes away. When I come back to idle it comes on. Could my switch be bad. Oil has been replaced recently Quote Link to comment

I think you can buy a mechanical gauge at a auto parts store that will have the right thread adapter and check it that way it is some sort of bpst thread. Mine sits about 25-30lbs at warm idle but I have seen some say 20lbs on a engine with some miles. Quote Link to comment

The trouble with a fast idle is mechanical advance can creep in an upset the timing. I would reduce the timing to 700 to be sure to set timing, then turn it up after. Why the 4x4 is 800 and the 2wd is 700 I have no idea. I see no reason they are the same engines. Quote Link to comment

I see no reason they are the same engines. the only reason I could really think of is for when you are going offroad and maybe in some more technical stuff you might want to have a slightly higher rpm for starting out and idling around. That is the only excuse I can come up with. Quote Link to comment
Joecar Posted June 9 Author Report Share Posted June 9 Having some transmission problems recently, Whenever I want to put the truck in reverse it’s very difficult to do so and the times it does go into gear somewhat it grinds very loud. Only way I can put it into reverse is either put it in reverse while the truck is off or when I first start it after a day. Quote Link to comment
NC85ST Posted June 9 Report Share Posted June 9 Try pushing the clutch pedal a second time. It’s entirely possible you’re having clutch problems, most likely slave cylinder. Quote Link to comment

It seems like it goes into every gear except reverse Quote Link to comment
