e30 si board schematic

[ceria]

I have a 1984 325e looking for a schematic for the si board from a vdo cluster. I have a couple of components that have been burned up need to replace. If anyone has a source or a schematic please respond.

Just replace the board...

How much is a board? Probably can fix for less the 5 bucks.

So here i go, jumping in on a 7 year old thread, that hasn't had any responses in that time. I'm in the process of having a lot of things done to my 87 vert. It's in really good condition, an overall 6 out of 10, the way it is currently, but I'm taking the extra tedious steps to make it perfect. One of my issues is a tachometer and econometer that work very sporadically, and a temperature gauge that might be possessed by a demonic force. I've tried the simple step of replacing the fuses, but that accomplished nothing. I'm nearly certain that it's the si board batteries. I'm pretty hands on, and capable of simple DIY things, but when it comes to disassembling the instrument cluster and soldering, I'm not at all comfortable doing so, and have zero soldering experience. So I'm looking for a professional to intervene, but can't find anyone near me in the greater NYC area, so far the best example I can find is a small company in the SF Bay area. I don't have a problem shipping it to them, but I'd rather just bring it somewhere local to me. If anyone knows of a place closer to me, please let me know, I'd really appreciate it, and want to do it pretty soon, while my baby is already down, being serviced for mechanical work. Thanks!

For the original topic, even I have never seen an Si board schematic. There will be several revisions out there to make up the few different SI boards and brands. I would love to get my hands on one too.
