    Default 05 DC over charging

    I have a 05 DC 4wd. Owned since new with 110,000 miles on it.

    Still has the original battery. Green light, starts fine. Truck is completely stock.

    For the last couple of years I have noticed it leads bad - the brace across the top is half gone with corrosion, and my entire inner wheel well has what looks like a light coating of rust/spray on it. It is rust colored, but you can wipe it down with the a strong brake cleaner and most of it will come off. It has made the underside of my hood look rough.

    Then the other day I replaced a rear/outside bed light - the ones by the 3rd brake light. On both sides, both bulbs had melted holes in the plastic housing assembly. It just looks like someone heated the bulbs up and the plastic melted completely down onto the bulbs and formed a hole.

    They may not have anything to do with each other, but could these two issues be a sign of over charging?

    I have read some comments about checking the ground for a poor connection. Can anyone point in a direction to check these things?

    I have no other related issues, nor has the truck experienced any other issues, except it seems to go through a lot of bulbs. I am on my 2-3rd set of headlights, and have replaced numerous market lamps, brake lamps, and 4-5 interior bulbs are out.

    Any ideas or advice?

    thanks!

    to check for over charging, start the truck and look at the voltage meter on the dash. it should be between the middle and the 18 volt notch. if is is pointing at the 18 then it is overcharging. and since its the original battery it could be causing the altenator to work harder and supply the battery with more voltage then needed. thus sending more power to all the accesories.

    Take off the alternator and many car parts stores (AutoZone, Napa, O'Reilly) will test it for free. I'm guessing that the regulator within the alternator is bad hence it's output is above normal. REMEMBER to disconnect the battery before attempting to disconnect the wiring to the alternator.

    The melting by the bulbs is fairly normal, even if the bulbs aren't super hot they will heat the plastic and over time it will look like the bulbs got super hot and melted the plastic.

    To check for overcharging, just use a multimeter across the battery terminals while the truck is running. Anything 15v and over you should be concerned, but I don't think up to that should be cause for alarm. I had my voltage regulator go back in August and I drove the truck for 2-3 days where it would hit 18-19 volts (via scanguage) but fortunately no permanent damage occurred.

    OK. Your battery is outgassing so badly that you have sulfuric acid dissolving the battery hold-down bar and etching the engine bay paint. Why haven't you replaced the damn thing already?
