Electrical A9L Schematic

[Mrg2783]

I have a 1992 GT Convertible that has a A9M

But a A9L works fine, does anyone have an A9L Schematic? Any schematics at least to help me figure out the Orange diodes.

I need to replace what appear to be bad zener diodes. Does anyone have information on what these diodes are rated at? It looks like some have a white blue line and someone have a white green line.

The repair shop wants a schematic to make sure they are replacing them correctly

This may be another option for you. No worries about finding schematics and hoping the repair place does it correctly.
Send it to ECU Exchange and get it back in perfect working order without having to provide any information. Many of us used this business and they have always done a great job to my knowledge including for myself.

If the repair shop doesn’t know what they are go get your ECU and send it to ECU Exchange. They have repaired a lot of the ones here for members and have an excellent reputation and typically find a lot more wrong with them than you would think. They are going on 30+ years old and several of the components are just aging out.

I was not aware that if it’s not repairable, they will send it back to you. Free of charge. That’s actually pretty awesome. My biggest thing was dropping a couple hundred dollars versus spending the extra thousand and getting a terminator set up but I’ve already done so much for this thing. Would be a waste of a Pro-M 80 mass air filter if I didn’t get this thing running right

Appreciate the direction I’ll be sending it to them. But it still wouldn’t hurt if somebody comes out with an A9L schematic for people. Unfortunately, a lot of people don’t have the money to throw away on something like that. If they have the schematic, they could potentially do a lot of the work themselves.

Sailorbob on eectuning.org came through with the schematic. At least it’s here now for the Foxbody world to see.

While I understand money is money, i wouldn't consider ECUExchange 'throwing away money'. Having a solid/working ECU will help remove potential hard to diagnose issues.

Awesome to get the schematic. Wish it was a tad bit sharper
