im I right in thinking the gray wire with the spade end powers the temp sensor and the reverse rev limit and the other a ground???thanks

Close to correct.

The gray wire with bullet connector provides a separate ground just for the stator Hall Effect electronic sensors which trigger the ignition system.

The gray wire with female tab (spade) connector is the input to the CDI for limiting RPM during overheat and similar conditions. If the temp sensor (Tan wire) grounds the gray wire then the CDI will enforce RPM limiting.

Reverse mode (Virage and Genesis carb engines) also activates this RPM limit by grounding the same Gray wire.

... my uncle has an auto electrician coming to look at a tipper truck next week ill show him the diagram you sent us and see if he can make it ...

I now have one assembled here in my hand. This one is made using the 78L08 regulator.

I do not have a carburetor engined Polaris on hand to test it with. If you are interested I can put in the mail to you. Just cover my costs.

Wire colors are close to correct, I used what I had on hand.

Grey (ignore the red stripe) is ground reference for the CDI to Hall effect sensor circuit. Connects inline with the existing gray wire bullet connectors between stator and CDI.

Orange is the switched battery power feed.

Brown is the 8 volt output to power the stator Hall Effect sensors.

that's the thing, after the engine is completely cool it wont start.

a run down of today is. would not start this morning, jumped with the 9v battery fired instantly (just fired, the engine was not actually running off the 9v battery) immediately after reconnected the brown wire to the cdi, engine starts and ticks over nicely.

... fast forward an hour, we try it again. Back to no spark! connect the 9v battery, engine fires. Reconnect brown to cdi, engine starts and ticks over perfectly on the hose again :/ ...

I forgot that this was a Virage.

As a test disconnect and fully bypass the LR-505 Start/Stop module. See if the engine now has consistent starting hot or cold. The original LR-505 modules are known to fail and can cause trouble.
