Manitou 627 electrical gremlins

[Bobby G]

Recently purchased a 2005 MLT627 which replaced our old 524. There are a couple of electrical faults that I'd like to get to the bottom of. The temp gauge is temperamental. It works 90% of the time as normal. Then if you shake the bucket with some vigour the needle will occasionally jump all the way to the right and get stuck..... New gauge???

I'm guessing this next is a bad earth somewhere.... With lights on and indicator the dash lights for side, dip and main beam all flash in time instead of the indicator light. All lights and indicators work as normal it seems the dash lights don't know what's going on

Any pointers appreciated

check all the earths, there's a bunch under the dash panels i think and there's a big earth wire on the side of the cab behind panel to the chassis.
