Lost the speedo, could a loose convertor connection stop the speedo from working ?

[RobEVo5]

Sometimes it works, sometime it don\'t. Either my speedo is knackered or I am hoping that a loose connection on the convertor may cause this to happen ?.

Am I barking up the wrong tree ? Are these convertors connected in line with of the wires from the speedo ?.

Cheers

earth connection probably, but it could be anywhere! took me months to find where mine was coming from.

Have you dimed the lights on the dash?

Not knowingly but the kids were in the car playing the other day. Could this cause this ?. Will put them on full brightness and see how it goes.
