The voltage regulator also contains fault detection circuitry. If it detects an unexpected voltage or any other problem, it can cut or reduce the power. But without square signal maybe came fault?? Found it was overcharging at 17v but soon as it goes into 17v range it would trip things out. The also contains fault detection circuitry. Let me tell you of a recent diagnostic experience I had at work: Not Charging Complaint 2004 Expedition 5. What the P0625 code means This code means that something has gone wrong with the generator field control circuit.
Nu ne pricepem la masini deloc, aveti idee ce ar putea fi? This big, old thread is bogging my computer down! Odd lights coming on, and no start. See my replies 2 to: Note: To answer this, please start a new thread, or send me a message. Dupa nici un l km a facut la fel. Incepator Mesaje: 1 Membru din: 29 Ian 2012, 11:02 Maşina: Ford horix scrie:. The blue wire is the dash light wire. The principle behind the smart charge system is that when a is cold it charges faster and is able to take a higher charge rate. It was the common cause of flickering lights on idle.

Thanks Ok unplug connector, and connect only a wire from battery + to pin 3 of alternator. I cannot understand why there is no power what so ever no click from the started absolutely nothing I then done the diagnostic check which came up with the same two faults and after 4 or 5 attempts it fired up again the fault lights had gone but are now back again. I followed the procedure that was posted in here a long time ago was it by Andy? In Conclusion I remember another similar experience many years ago , that involved the same issue. Apologies for bumping a very old thread but this is the only topic I can find that's relevant so joined up and look forward to being part of the club! The recall is to tighten it up due to the high resistance in the cable causing a volt drop from one side of the engine bay to the main fuse board. Need help with a P0620 code? Additional comments for consideration regarding the P0620 code The same problem that caused the P0620 code to be stored could also be behind others. Cei de la service mi-au zis ca nu e nimic grav cu acel senzor si ca pot merge si asa, eu oricum am dat comanda si urmeaza sa il schimb.
Then you said i must cut one wire and join it direct to battery +. What repairs can fix the P0625 code? But is possible on crash the ecu can damage if the wires was cut. If its a diesel, the wires can rub through the metal bracket next to the alternator. Sorry but my english is not good. Did read that some have problems with wrong battery.
The alternator would only last about a week and the owner of the vehicle would bring it back with to the shop. Well, one of these used-car lot owners sent a 2004 Ford Expedition that had had the alternator replaced with a used one. In caz de nepornire se releva adesea acel cod de eroare , fara a fi insa senzorul defect. This causes the voltage regulator to begin controlling the generator field circuit. Incepator Mesaje: 10 Membru din: 17 Mar 2013, 18:12 Maşina: Ford Focus 2. Part of the system takes a reading from the thermostat to see if it has opened and what temperature the engine is operating at.
If the regulator detects a problem, the regulator will ground the generator turn on signal circuit, pulling the voltage low. If it has, dropped me a line and share your diagnostic and repair experience with the rest of us. If the fault detection circuit senses a voltage other than what is expected, this P0620 code will set. What repairs can fix the P0620 code? Sets a Pending Trouble Code after one failed driving cycle. The good thing was that I didn't have to install any of them to test them. I know the car starts and runs fine even when doing 400 mile round trips and short ones the calcium always starts no problem. P0335 - Crankshaft Position Sensor A Circuit Malfunction Simptoma releva problema de immobilizator sau pompa injectie defecta.
When is the code detected? Hi guys ,my focus 1. The resistance registered was 60+ K ohms. Well, my boss and owner of our little repair shop ordered the alternator. Repair Solution Having seen this problem so many times before, over the course of my repair career, I knew that I needed to immediately check the resistance between the alternator's pin 1 and ground preferably on the alternator's case. After About the fifth try the lights went out and the car started I drove it home switched it Off and was then presented with the same problem.
Problem is soon as you take your foot off the gas pedal the voltage drops for a very split second down to 13v then back to 16v very quickly. Also, check the battery fuse in the under-bonnet fuse box possibly 3 amp. I'd have got on to load testing after his answers. Examples of control modules that may catch this problem include, but are not limited to the antilock brake control module, the body control module, the alternative fuel control module, the instrument panel control module, the turbo control module, the fuel injection control module, the cruise control module, the anti-theft module, the proximity alert module, the traction control module and the climate control module. To make the long story short. Utilizing freeze frame data will help with this. Thanks very much for the time spent responding to my queries, very much appreciated.
It shouldn't be no, as long as they've replaced the correct alternator and you have the correct. YourMechanic is here to make it as convenient as possible to have your vehicle diagnosed and repaired. Everything discussed on this forum is for experimental and educational purposes only. I can't copy the flash, y search for flash in forum by ref. These are cars that never get new parts for the most part since the used-car lot owner wants to maximize his profit as much as he can.
