Was wiring up a license plate light the other day and it looked good.

This morning when I took my bike out, the tach did the regular start up spin, but after that, it and the speedometer were out of commission. Tach won’t budge and speedo says 0MPH while riding. There’s also an engine light on and it says Error 1.

Any suggestions as to what could be wrong?

From page 8-66 of factory service manual "Er-1" means loss of communication between the fuel injection ECU and the instrument cluster.

Check that the multi-pin plugs for both the instrument cluster and the ECU are securely connected.

This doesn't appear to have anything to do with license plate lighting ... but try unplugging that to see what happens.

I agree probably a loose connection in the wiring harness. If not and you need a need instrument cluster, Ebay might have a few available. There are links on this web board with the service manual and wiring harness download.
