SI board schematic - moto board

[lentildude]

Hi, Have had bad corrosion on my Moto SI board from a 323i 85 model. Nowhere can I find a schematic diagram of this board so I can figure out where the dissolved copper tracks are meant to run. Does anyone have an identical board that they can perhaps post a close photo. That way I can at least jumper the missing tracks. thanks for any help.

Your pictures are not loading. Chances are if your electrical traces are damaged beyond repair, the integrated circuits also have battery acid damage. Those IC's are long discontinued so your only option is to replace it. I have several of these older SI boards in stock and refurbished if you need one.

Thanks but will try linking the missing tracks first, replacing battery and testing. Rest of components seem fine. Strange pictures loading this end here are the urls..

Pictures are not working.

hires pics should now be displaying of SI circuit tracks..


my main reason to fix this is not for silly LEDS/service lights but I read the temp guage goes in and out through pins/circuit track via SI board circuitry to temp meter. A faulty temp guage may be to a bad SI board connection. My temp guage hasnt worked for years and its not the bolt on back of temp guage, not sensor, not the wire to cluster so SI board only thing left...

Not worth the time to try and fix that IMHO. I can't think of any reason why not to just get a used board.

^^ Agreed, snag a used cluster and swap it out or just buy the board.

If the US SI boards are compatible, I have a used one I'll get go for $5 + shipping (to Aussie-land probably about $10-$13)

quidmaster is your $5 board moto or vdo? does it look like mine?

[squidmaster]

I actually have a VDO and a Motometer. I'll let either go for the same.

PS just ate a huge bowl of lentils, veggies, and rice.
