"I have just bought a 1987 120
"I have just bought a 1987 120hp evinrude.The engine runs well and has a newer power head.I have notice that the temp sender has not been connected and it could because the power head is off a later engine!.If I connect the purple to + ,dark grey to the - and dark blue to the u the temp seems to work.But if I earth out one of the temp senders to the block the warming temp alarm comes on,but the gauge dose not move.I have traced the two temp sender wires and it seems that one wire goes to no where and a wire goes to the vro pump.Can any one comfirm how these engine should be wired up."
