So I'm having trouble staring when the car is warm, thinking it's the cts but the gauge seems to work fine. Is there a seperate sensor for the gauge? Or will it be working but sending a signal saying it's cold?
I've also got a problem where until the car warms the volt gauge shows at 14.5v when driving, on idle its around 13. But when the coolant temp reaches about 90c the charging dies off to nothing above 13v. Also when the heater is on the voltage is about 12v.
Any help or suggestions in the right direction would be amazing
Thanks:)
