Speedo & RPM not working sc400
So a few days ago the speedo and RPM meter stopped working. Everything else works fine and the dash still lights up, but the two just doesn't move.
Someone had told me it was the ignitor
looks like this
but im kinda doubting it... Ive searched around and there hasn't been a lot of answer to this. Anyone have any clue?

The speedo and tach needles have capacitors on the back of the cluster that help to power them. Pull your cluster and if the needles are good have all of the capacitors on each needle replaced at a local electronics repair shop. You could also DIY it if you are handy with a soldering iron.

Speedo is controlled by the main chip, that's why there is no fix posted.

I don't know why people still quote the lighting fix for a digital australian soarer backlight (or occasionally some LS cathode needles), it's been 8 years since anyone posted it. (PS no they don't).
No such thing.

speedo has been fixed, RPM still isn't working.
some how both VSS #1 and #2 are both bad. I really don't know how both went bad at the same time, but I'm glad I got the speedo fixed. Now to figure out why the RPM isn't working.
