I'm attempting to get my 1998 Ford Expedition 5.4L V8 to start after sitting for a few months.
Initially, the battery was dead, so I put it on my charger for a while. After the battery was charged I put it back in the car and it refused to start.
Attempting to start it after the battery was charged led to the following symptoms:
- Cranks for about 1/4 of a second, then completely stops. No clicking from starter.
- Loss of power on dashboard, interior lights, etc.
Next, I thought "well maybe the battery is bad", so I put it on my jump starter. Same issue occurred. So I made the assumption that "maybe my jumper box doesn't have enough power", so I plugged in my Camry while it was also on my jumper box. Same symptoms.
The really weird thing for me is that the loss of electrical power after attempting to start it doesn't fix itself when I stop attempting to crank it, like a low battery situation. The multimeter still shows battery voltage, but the interior lights and dash don't light up when I stop trying to crank it. These issues only get fixed when I remove the battery connections, and reconnect them.
Any pointers in the proper direction are truly appreciated, thanks in advance.
