Help with vacuum issue (I think!)
Cougar replied to Yes I Own an MGB's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Check the intake manifold gaskets for leaks. They are a common failure point. -
Thanks for the notice Daeron. I goofed up again. :-\

Clock issues?
Cougar replied to Sweet82's topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX
I just sent you a message Howard. I would just send it by First Class mail to save costs on shipping. -
I seem to recall a notice from CCR (Emily) that they may be no longer selling the EA81s since they can no longer get parts for them anymore. You may be able to have them rebuild yours though.

Howards11, Are you still looking for someone to fix your clock? If so, I will help you out. Glen -
Here is a link to a book you may want to look into getting: http://www.amazon.com/Beginners-Reading-Schematics-Robert-Traister/dp/0830676325/ref=pd_sim_b_5/103-7678949-9696629

To learn about certain symbols you should be able to find out the info by searching the web for electronic symbols. There are a lot of good text books on the market that can help you learn basic automotive to advanced electronic information and repair. You can search for them on the web and also check your locale bookstore and library.

I agree with Gloyale. Check the fusible links. The alternator output lead is always hot to the battery and the wire may have grounded out when you tried to start it, causing smoked link.
-
This is kind of a strange problem. It may be that the new battery is causing the alternator output to have some extra noise on the output and causing false error codes to be shown by the ECU, but I have never heard of that kind of thing happening before. I also have never heard of a battery for a manual transmission.

In-depth informations about EA82 ECUs

It looks to me that it may be Q600 is the one I replaced. By checking the transistors with a meter you will hopefully find the trouble. -
I didn't know there was a light for that on the dash. I think you are right about the warning being caused by a electrical circuit. The EGR circuit usually has a solenoid wired to it and the ECU monitors that.
-
I think you are correct about the switch. It seems the most logical point. I haven't done that job myself so I can't say how hard it is to do that. I don't think it is real hard though it may take a little time to do it. Hopefully just cleaning the contacts will fix this problem but you may have to replace it.

oy ANOTHER PROBLEM? Check Engine?
Cougar replied to BruceY's topic in Old Gen.: 80's GL/DL/XT/Loyales...
If you are trying to clear the 35 error code and the ECU isn't happy with the circuit condition it will still come back in. As soon as the ECU sees the right circuit condition it will stop the error. There is no delay in the reset. -
oy ANOTHER PROBLEM? Check Engine?
Cougar replied to BruceY's topic in Old Gen.: 80's GL/DL/XT/Loyales...
The 35 code will go away as soon as the ECU sees a normal current in the circuit. It appears the ECU still isn't happy with what has been done for some reason. -

I wouldn't change Q702 unless you prove it is bad first. It isn't the transistor I changed out to fix my ECUs. -

Well this may not be very easy to do by posting advice but let’s give it a try. First off, I will say if you would like me to work on them myself I would be willing to see if I could get them to work for you but I can't guarantee it. If you don't have the proper tools and skills you can damage the board if you aren't careful, though it wouldn't be any real loss right now as it stands. The transistor I replaced is similar in style and location as Q600. That is a TO92 style. I'm not sure but, Q702 may be the transistor that is tied to the fuel pump ground lead. By tracing the lead from the fuel pump lead connection it should lead you to the proper driver transistor if that isn't the correct one. The transistor I replaced was the stage before the driver stage unit. Using a meter in the diode check position should work in finding the problem if it is a transistor. You need to be aware of the circuit it is tied to though for any possible discrepancy in the reading, as it could mislead you in thinking the transistor is bad and it really is good. It just depends on how the circuit is designed and what it is tied to. This takes experience to figure it out. Hopefully you have the same problem I did. The replacement transistor was less than 2 dollars. I will be gone for the afternoon today but will be back this evening to check back with you. -
After reading this post I can think of a couple of things that may cause this to happen. First thing I would do to check into this would be to run a ground jumper from the negative battery post to the dash ground to see if there is a grounding problem. Along with that, check the wire connection between the disty and the tach to make sure it is good. If those things are ok then I would suspect that the tach is picking motor noise generated by the blower motor. Checking the power to the motor with a meter set to the AC volts function may show the noise up.

I thought the same thing as Bulwnkl said when I started reading these posts. I haven't tried the product myself but I sure would if I needed it. You may want to try it and see if that helps quiet the slapping at least some. Here is a link to their site. Check out the reviews from people that have used the product. http://www.auto-rx.com/

The test method I used to find the problem was using the diode function of the digital meter and checking the forward and reverse directions of the transistor junctions. I can't remember now if the junction was open or shorted. Your unit may have a different problem since the polarity was reversed. My unit just quit after the alternator was replaced. I think the higher output of the new alternator took out the weak'nd junctioned.
