  1. saw a rub through like that once on a 22RE pickup. the temp gauge read high. after replacing the radiator, thermostat, fan clutch, water pump, I found the wire harness that comes up and through the intake to the injectors and senders was rubbed through. the only wire affected was the one to the gauge sender. one strand of wire was making just enough contact with ground to make the gauge go high.
  2. Food for thought to all of us... I worked on many Toyotas in the 10 years I wrenched there. Anytime I ever removed a fuel line, I would go back and loosen the gas cap. I don't know the physics of it, but if you leave the cap tight, fuel will leak out of the line you have off. Loosen the cap, and it can sit for a month with lines disconnected. I think the fuel expands and makes a slight pressure that pushes it out of the open line. With the cap loose, it just expands and contracts and any pressure just vents out the cap.
  3. Terrible to lose a nice MH like that. I sent you a PM with a question
  4. No paperwork? it's got way more than $200 worth of good parts. I bet they'll pay someone to take it rather than deal with code enforcement.
  5. Found this on CL, https://inlandempire.craigslist.org/rvs/d/wildomar-1970s-toyota-mirage-come-get/6891407932.html
  6. I tried to get codes from jumping the DLC, CEL blinks no codes, OD Off does not come on at all. Isn't the OD master switch an input to the ECM? how does the voltage get to the switch if the bulb is between the fuse and the switch? I can't imagine they would push power to the switch through the computer and have power coming from the ignition switch and fuse too. I do not have the factory wiring diagram, only the page that was posted here, and going by that, I can't see how the switch could work if the bulb was open. if you look at the pattern select switch in the diagram, if it were open, you'd lose your ground to the switch. no light, no ECT Power function, right? on the OD2 main switch, when you close the switch, you'd be grounding a circuit with no power leg if the bulb was open, no? and if the power came from both sides, how could grounding the wire before the bulb (OD2 side) make the light work under any circumstances? it would be a short to ground.
  7. The OD off light never comes on. key on/button/jumped DLC. never. Am I reading the wiring diagram right? It looks to me like if the bulb were open, the OD switch would not get power...
  8. I never took the instrument cluster apart to check the bulb, but I tried to make it work through the wires from the shifter. there's only 2, and I applied ground to both. but... it looks like from this diagram that if the bulb is out, the OD main switch will not get power
  9. anyone here have a V6 with OD that works properly? Does the OD OFF light come on at key on before engine start up?
  10. That's exactly what I was thinking, downhill will not be something I'm not looking forward to. gonna fix it before I go into any real mountain travels. thanks for the input! I'm pretty sure it is going into overdrive. the drop is about 350 rpm. I can also feel the lock up and see it on the tach, it is less of an rpm drop.
  11. sorry all for the late reply, am out of town on work and coach is at home. Yes, it is a six cylinder, no, I have not accessed the bulb to see if it's good. I am positive that the overdrive is working...on the freeway at 55-60 mph, there's a distinct shift and RPMs drop to 1900.
  12. well, the OD OFF light never comes on, even with the initial key on check. the diagram I posted is for a 4 cylinder A43D, not a A340E, which i think is the trans for the 3VZE. I took the plastic off and found a two wire connector coming directly from the shift lever. could not find the relay.
  13. I will check that fuse, but the engine fuse must run more than just the OD. In any case, I don't think the OD OFF light is confusing, it just doesn't work. the button is not momentary...it has an on (in) and off (out) position. I have overdrive. the light and the control of turning overdrive OFF is what I don't have. So, grounding terminals 3 or 4 energizes the relay coil and opens the relay switch, and turns off the overdrive, right? then if that's the case, wouldn't an open circuit at 2 (blown engine fuse) cause the OD NOT to work? I'm just saying, it looks to me like the schematic shows a normally closed relay contact (1&2) makes a complete circuit to run the solenoid. anything that opens that circuit, fuse, or grounding relay terms 3 or 4, would make the OD turn off. I'm thinking if I ground 3 on the relay, I will get my light back and be able to shut it off again. gonna go try that. Thank you all for the input. If that works, I will buy the shifter that's up on Ebay.
  14. Thank you, I will probably buy that one. is the OD OFF light supposed to come on when you turn the key ON? would a broken wire at the switch make the light never come on?
  15. right, only problem is that I can't "shift" to overdrive. put it in drive and listen for the shifts. turning the button off makes no change. the only way I can get it out of overdrive is to mash the throttle some
