Dash "craziness"

[SteveSPG]

most of the time, my dash is absolutely fine
occasionally, it has a minor fit for 5 minutes, then settles down

the temp readings and oil pressure readings will vary wildly for no reason, often accompanied by a "oil /water/pressure sender fault i quick succession

occasionally i will get a "oil pressure 60psi " warning flash for a second, then disappear.

the rest of the gauges and readings are unaffected.

It could be earths, I've checked, but ill check again
it could be a 5v signal to the senders is erratic (anyone know where that is generated from) it is so intermittent that I've not been able to get a meter on it to check


any suggestions?

It could be the dash ecu in the foot well by the loud pedal in a pocket against the wall, it would be worth taking of the connectors, they look like big computer connectors clean them up and spry some WD40

Worth a try

Hi Steve

I had this on the Tam when in Europe....efi fault, water temp 187*c oil temp 120*c, fuel pressure warning, amongst 4 or 5 others plus it died on me twice and whilst kaneing it down the splugen pass in Italy had no power steering I was fortunate not to go over the edge of the drop... Thank goodness for my weight training or it would have been a far different outcome.... It turned out to be the footwell earths

You need a 17mm socket...the bolt is on a threaded insert. I tightened it all the way up.... Then took the battery out and tightened the 17mm nut on that side. All sorted
