S13 Digital Speedo repair solution - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

There is a well-known manual for repairing a speedometer with replacing a capacitor. But after repairing my own and several others, I discovered that in fact the problem is not in the capacitor, but in the pins with which the small additional boards are attached to the main board:

All speedometers I have seen have had this problem. The soldering on these pins just cracks over time. It would seem that you can simply renew the solder. But the problem is that the boards are made using a very strange technology with deposition of a conductive layer on a ceramic substrate. And after cracking off the spraying, there is simply nowhere to solder. After suffering with the restoration of a couple of pieces, I decided to just make the boards from scratch.

Here's the result:

And here are the gerber files and lists of components, with which you can order the manufacture of boards:

Most of the components can be simply rearranged from the old board, but there are also spray-applied resistors. They will have to be bought new.

This is very neat, have you made a functioning replacement yet?

Simon_Ru · 03-04-2021, 01:27 AM

I've ordered a few boards, they're coming. Not tested yet, but it should definitely work. Will update later with real photos and test results.

andisan · 03-04-2021, 09:35 AM

Are you going to sell them??

And if you do, good thing I saved mine

I had no such plans. But if it needs to, I can create a sales topic when I get the boards.
Anyone can order it yourself at jlcpcb.com or pcbway.com with the files above.

hiimelvin · 03-04-2021, 04:26 PM

I would definitely purchase a few sets of boards if you offer them!

DiscountPirate · 03-14-2021, 12:52 PM

props for your soldering and wiring knowledge and skills.

Simon_Ru · 05-14-2022, 07:42 AM

I've got several complete and tested boards now. PM me if anybody needs them.

Nope not yet either, checked his profile and was last seen somewhere begin may

Simon_Ru · 05-24-2022, 09:42 AM

Fck, completely forgot and didn't think that so many wanters here. Please, check your PMs. Repeat if I missed someone. Sorry for delaying!

Need to tell it again: All speedo-s that I've seen had problem with the boards. That's why you need them definitely sooner or later.
But some speedo-s(about 10% from my experience) have got additional problems with power board or main cpu board. So if yours aren't working now, these boards can't completely fix it in some cases. Disclamer

So maybe this is a dumb question, but how do these boards get installed, do we have to unsoder the stock boards, and resoder these into the unit as the replacement?

Simon_Ru · 05-26-2022, 12:04 PM

Yes, stock boards need to be broken out at first (the most simple way). Then you need to clear holes for new pins inserting.
This is really easy for any hobbiest or electronic repair master.
