Speedometer stuck on max *Yay*

Greetings and happy eastern,

So.. my long pulsar project is coming to its end, got everything done and car working and going for a tune asap.
But the problem is that when we removed and fixed the wiring under the steering wheel where we removed 4 Alarms (Yay for japan).
After that the speedometer is stuck on 180, I will start to troubleshoot the issue but just wondering if you have any ideas where I could start.

Pointers :

- Every single warning light etc rev meter is working perfectly.


Cheers !

Strange!
It wasn't doing it before you took the alarms out?
Does it return to zero when you turn off the engine and remove the key?
You haven't fit white dials recently?

Sounds like a earth or cable to the delimiter or clocks to me

No it was working perfectly with the old megasquirt ecu and setup.
We changed ecus and bought a new wiring harness and removed the alarms and other boost meters etc and put the pump behind a switch due to the relay being dead.

And atm its stuck on 180 even with no electricity so nope it doesnt go back to 0.
And no white dials fitted no.

It's got to be something with the wiring. I remember back in the day wiring a autometer gauge incorrectly and it maxed out the gauge exactly as you are describing.

I will check the wiring again to see if I can find any weird stuff there.
Thank you for the tips, now lets just hope Ill get this sorted, theres only 2 issues left on the car and then it will get a new paintjob etc but if I cant get these fixed then I will give up with this one and sell it in parts goddamn
