Heres the deal. I just drove about 40 miles, shut my truck off for about 5 minutes and the thing will not start. This is the second time in 2 months.The truck light is dim when the door opens (obviously) and when I turn the key to start it makes no noise, no click-click-click. This has happened before, but I shut the truck off for longer, so I thought it was the battery. My buddy's Catera couldn't do it, so he went and got his Super Duty and it fired right up. I just went to jump it again with another V6 and nothing. There is a good connection when cables are attatched. Everything powers up (interior lights, gauges, radio etc..) but will not start. Is this the alternator going bad. The positive terminal on the battery is always corroded. I always clean it. It has a battery out of a 4-banger ranger, same year, just different engine. Does that make it a possibility? Truck has about 77,000 miles,2wd, 3.0, Edge with power everything and A/c. Any insight would be very helpful.
Use a multimeter at the battery posts. You should get 12+ volts with the engine off and 14+ with the engine running @ about 1500rpm.
The battery is second hand, so you might want to have it load tested.
If the running voltage comes up short, like 12-13v, have the alternator tested.
Also, have a real good look at the cables & ALL connections. If the cables have corrosion in them where you can see it, then they may only require a good cleaning or even replacement.
AL.
I agree with Dealford on havng the electrical system load tested. Why not run this puppy by your favorite autoparts store, like Advance Auto, AutoZone, ect, & have them do a no cost system load test, with their portable machine, It'll likely snif out the problem. Sounds like a shorted cell in the battery, but you could also have a alternator/regulator problem too, that if left unattended, could fry any replacement battery. So have the ENTIRE electrical system load checkd IN the vehicle. If you have to rplace the battery, don't skimp on the amp hour size, install at least the amp hour size specified in your owners manual or more amp hours if you have plenty of add on electricals, like lights & sound. Let us know what you find.
