7/9/2023 0 Comments 2010 ford escape alternator![]() ![]() ![]() Any trustworthy sites such as auto zone just don't have the particular one I need related to my daughters car. Even the purchasable ones don't appear to guarantee that your going to get what you want. If I found anything at all they want you to purchase or download some app that I am not sure is trustworthy. I did a quick voltage drop across the battery terminals and main accessible connections which checked out fine and since it started getting dark and cold outside I called it a day and decided to go inside and see if I could pull up some wiring diagrams from the internet. At no time does the battery light come on at the same time even though it too cuts in and out it does so on its own schedule. At the same time as the steering cuts in and out fuel gauge, tach and radio cut out and the heater doors move same as when you turn key off and on. Another thing that popped up was a sudden loss of power steering (this car has electric power steering assist) which tends to cut in and out. So I am thinking bad or intermittent connection of ground or positive wire or battery voltage sense wire if there is one. I am also thinking since it will charge up to 16+ volts the Alt itself is Ok. I am assuming that this alternator is regulated by the engine ECU rather than a regulator in the alternator though I am unable to find out for sure. then down to 14.7 and then back up to 16.7. So yesterday when I put the voltmeter to it the voltage was at 9 volts I started the car and what you know no battery light and it is charging but next thing I notice its going right up to 16.7 volts. At the same time I checked the charging system and it was fine. I had just replaced the battery about 4 months ago which was still the original (so 9yrs old) Which I load tested first and it failed. While driving it I noticed the battery light came on. Here is the issue or combined issues Yesterday I took my daughters car to replace the heater resister. Any help here in finding or providing schematics would be great. I have an issue with my daughters 2010 ford escape but trying to find electrical diagrams has proven a total waste of time. ![]()
