Make sure the wire is on the sensor on the engine or the wire is not broken anywhere.
Happy daysAll fixed. There was a break in the circuit board on the back of the binnacle. A friend with a steadier hand than mine bridged it with solder. Now on to the next problem...
Looks like they sent you old stock http://www.paddockspares.com/amr2092-amr2092.html so you ordered the correct part but got the older one.I was super frustrated about it. I'd ordered STC4104 from atlantic british but received a different sender when the package showed up (AMR2092). I'm not sure if it was britpart, but it failed pretty darned fast.
