Battery dying on Ford F550

We have an 2008 F450 that was built as a Rescue vehicle for our fire dept. If the truck sits for more than a week when we try to start it the battery is dead. I checked the cables connected to the battery and it seems the one that operates the dome light on the hood and the flashing of the headlights has .5 AMP continually running even after the fuses are pulled for the light and flashers. Can you tell me what else is connected to that cable that may be drawing on the battery ? Also how can we correct this problem ?

If this unit has hand light ( box lights) chargers check them. box lights will kill batteries over 1-2 days

Turned radio off then battery died, got vehicle fixed but no power to factory radio, all fuses check as good. Is there a trick to getting the radio to turn on again?


when the battery dies or is removed , the anti-theft code of the radio kicks in and the unit will not work again until a special code for that radio is reinstalled
the code could be in the user manual in the radio use section ,or there are sites on the net that may have the code for you

There is no serviceable fuel pump relay on these vehicles. It is built into the Central Junction Box (aka the main fuse panel under the instrument cluster). Hope this helps.

My engine has seized after being laid up for approximately two years. How can I free it?


Remove the spark plugs and squirt some oil down in the cylinder heads. let it sit for a week
Remove old fuel from the fuel lines and tank .
Put a good battery in it.
If vehicle fires up after a week of sitting, shut it down and change oil in the engine, diffs and trans, you will probably notice that seals may weep oil for awhile if they continue you will have to replace those seals.

1988 ford taurus battery problem


regulator is built in to alternator, you need to have it tested. My guess is it's time for a replacement. Most parts places like autozone, will test it for you & sell you the proper one to replace it.
