AIR VENT SOLENOID/IDLE SOLENOID

1989 Mazda b2200

Electrical problem
1989 Mazda b2200 4 cyl Two Wheel Drive Manual

Below I have included all the previous posts related to my problem. It seems to be one thing after another. Truck was running fine with a jumper wire in place to what You called a idle solenoid, but my manual calls an air vent soleniod. Like I was saying, running fine, but was shutting off when it wanted. Replaced ignition controller in distrubitor and it now starts when we want it to and shuts off only when we want it to. But now I would like to remove the jumper from the air vent solenoid and have it receive power from the proper source. The continuity of the wire going to the solenoid is good if I jump the plug that goes into the pressure sensor that feeds thhe solenoid it clicks and I found that if I supply power to the black/white stripe wire that I traced it to that goes into the top of the carb it also makes it click. This is as far as I can get with out some help.I would like to follow through on this till the problem is fixed completly. I donated for the first question and was not sure if I was entitled to follow ups on that question or not, so I have donated again. Also, is there any where on line where I can find detailed wiring diagrams for this truck? Thank You in advance and have a good and peaceful day.

Hello,
I seem to have the same problem as need help bad. My truck runs well, but when you let off the gas it stalls. The carb has been rebuilt and the vac leaks as far as I know have been taken care of. I checked the idle solinoid as You told him and mine does not click when the power is on. When I jump the solinoid from the battry it clicks. When I hold the jumper in place it idles much faster. With the power on my meter reads 0.08 volts at the solinoid. Please help
Paul

Paul:

It sounds like the wiring to the solenoid is broken internally. Follow the wire from end to end and check for continuity. I feel you will need to replace the wire.

Hi Paul,

You should have replied to the previous post so that whoever was attending to you can be notified and respond accordingly.

Here are the wiring schematic, you might have a fault with the control unit.
