Hi Everyone, I was hoping I could borrow a minute of your time to see if any of you have had a similar issue.
I have an 03 6.0L Excursion 190,xxx miles, I pulled my boat out of the water on Sunday and parked it until Wednesday. I got in and the batteries were almost dead, I figured someone seated in the rear had been playing with the interior lights or dvd player so I charged the batteries and fired it up. I let it run for 15 minutes then took it around the block and noticed the ABS light was on. I tried to start it this morning (Thursday) and batteries are dead again. Either the batteries are not holding a charge or something is drawing from them....
Some guys on this forum said this happened to them and they replaced the alternator which fixed the ABS and dead battery issue. I took my alternator off and had it tested it passed the test. Next I was thinking about getting the batteries tested after that I'm going to have to call the mobile powerstroke mechanic
Any suggestions would be greatly appreciated, thanks!
Thanks I had the batteries tested, they were both good so I'm putting a nice charge on them and reinstalling tomorrow. I'll clean all terminals and apply some dielectric grease and hope the ABS light is off.
Did the ABS light stay on after you drove it? If the batteries go completely dead then the ABS computer will reset and the ABS light will stay on until you drive it over 10 MPH. and let the ABS system verify everything's working. If the ABS light went away as soon as you drove it then the ABS light is unrelated to your issue.
Both the batteries tested ok and the alternator?! If so then you must have a heck of a draw on the system to kill the batteries that quick.
Well I just reinstalled both batteries after charging and drove it to run an errand. ABS light shut off before I even got off my street the only thing I found left on was the light above the passengerside rear seat. Guess I will drive it all weekend and see what happens
