the glow plug controller is grounded through the coolant temp sensor . @ 16,000 ohms resistance... normal...seems to have to have it to work. new controllers by international seem to be real resonsive. smaller electronics.
what year model is it? Is it an IDI or DI powerstroke? with the later model powerstroke the pcm provides ground for the relay need Moore info to answer
2000 cougar ,ignition relay has fuse 23 on inside fuse block energizing coils,faulty trunk ajar relay ?
horn relay is under passenger side fender. to access it you need to remove the plastic liner inside the fender
look right above the passenger side valve cover, right behind alternator, that is the glow plug relay.
How do I test the air intake heater relay on a 7.3 desiel
when the relay is working, it's energizing the blower... jump power to the motor, (be the relay!) to see if the blower works... also, listen to see if the relay is clicking "on" when you turn the switch on the dash(could be a switch) good luck d
Sounds like you need to change the glow plugs or the glow plug relay switch or both.
A relay is an electrical device that acts like a light switch. But instead of a person turning the switch off and on, it is done by energizing it from a remote source. So when you hook two wires to a relay, if the relay is normally open, there will be no connection between the two wires until the relay receives a signal (outside source to energize relay) to close. Simply put, an open relay is the same as a light switch that is turned off, and will always be off until told to turn on.
I have been looking behind radio in the power distribution box , nothing yet chiltons does not know ford dealer does not know
In a properly designed and installed system, nothing will happen. If you press the start first the contactor or start relays may close energizing the motor briefly but the relay will open and stay open when the stop is pressed.
Because it is connected (by a few wires if I'm not mistaken) to the blower motor.
because they had that in the B.C.s
