So I finally got all the dash lights in the RD working and noticed the lightening bolt on with Code 1-7 , which should be low coolant level.After checking the coolant tank and refilling it the light still remains.I disconnected the low coolant sensor and used a wire to complete the circuit but light still on.There seems to be no voltage in the connector whatsoever and I have traced the cable and can see no damage to it.So now what? Does this affect my engine performance? 96 rd688s 350hp
