Mason Alarm

Fitted a Mason Alarm today as per instructions. After driving for approx 400 metres temp gauge went all the way over to the right passed the ( H ) mark and stays there. Rechecked to see if I had wired it correctly and seems to be right, any ideas

be careful you didn't overtighten screws at back of clocks,this could earth gauge and make the needle go straight past the red,or not work at all,(wonder how i know that?)maybe best to disconnect and check normal operation of temp gauge.

I've disconected the Mason Aarm but the gauge still going passed the H mark just with the ignition on. ( What have I done )

I noticed when I fitted mine that the instrument circuit board is quite flimsy. You may have done some damage to it perhaps. I don't know how much a new instrument cluster would set you back. Before you look into a new cluster you could take the cluster all the way out and look for obvious damage that could be soldered. Also check that the electrical connector is clipped together well.

You could get in touch with Dave Mason to see if he has any ideas.
Good luck.

sounds like it is earthed out or shorted,when testing temperature sender unit i touch terminal on the actual temp sender unit to earth ,and this has same effect,lets you know if its the gauge whats faulty or the sender unit.
you have probably overtightened the screws or accidently touched a circuit and shorted it out,try loosening the screws (3) at back of clocks with ignition on and engine up to temp,sometimes if one of the screws is not tightened or slightly tightened your gauge will work.
