Titanjas Posted November 27, 2013 Report Share Posted November 27, 2013 I have a 2007 edge se. About 3 seconds after I start the engine all the electrical compoments turn off. The engine still runs. The int. lights, gauges, seat motor, a/c and heat have no power. the radio works but has a lot of interference. The fuses look o.k. Any ideas?

WWWPerfA_ZN0W Posted November 28, 2013 Report Share Posted November 28, 2013 Sounds like something shorted internally. Do your turn signals work? Windshield wipers? If all the fuses and accessible wiring look OK and haven't been drenched recently, I would suspect the Smart Junction Box (SJB) having an issue. Battery/alternator should be checked for voltages also. Quote Link to comment Share on other sites More sharing options...
Titanjas Posted November 28, 2013 Author Report Share Posted November 28, 2013 turn signals and wipers work. Battery was checked andis ok. The alternator is running at 19 volts. There are 19 volts through the fuse box under the hood. Things work intermittently. Is there a way to check the SJB or do i need to take it to the mechanic? Thanks Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 29, 2013 Report Share Posted November 29, 2013 (edited) 19V is way too high for the alternator output. Should be more like 16V per the workshop manual. What is the battery voltage? See if you can pull the codes first, but this diagnostic path probably applies to you: DTC P0563 — Charging system voltage was higher than 15.9 volts - CAUSES Bad battery ground High resistance A sense circuit Generator Battery PCM The diagnostic path listed is quite extensive. I attached a zipped TIF file to illustrate. The SJB should be checked out by a qualified technician, if it comes to that. 2007 Ford Edge Charging System Test if Generator OverVoltage W.zip Edited November 29, 2013 by WWWPerfA_ZN0W Quote Link to comment Share on other sites More sharing options...
