It started working this morning but is not very accurate so it's a possibility I might send it to a shop, how much would I cost for a digital gauge internal swap roughly?
when I connected a green/white wire to a blue wire and ran a black/white wire to the + on the coil it worked!. But the coil is now only getting 9v when running not 12v, is there another wire that's meant to run to the coil for supplying 12v when running? I don't have a blue/black like some of the diagrams show for a electronic distributor being a 77.
Thanks for your help! Lochie.
