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?
