Runs fine, but I've noticed recently it's getting slow to turn over (as if the battery isn't charging properly). Today I also noticed no headlights, no taillights, no reverse lights, no in-cab lighting or radio in the overhead console, and no warning beep when you first turn the ignition on. I don't know what else is failed...that's all I've found. I found one corroded red wire at the positive terminal so I assumed that was the culprit. Repaired that and replaced the battery while I was in there since it's almost 5 yrs old. Starts and runs fine (for now) but all of the above failures still exist, and I'm assuming it's still not charging. I've checked all the fuses I could find including the 40A cab pwr near the battery and the front power and rear power fuses in the panel. Dealer told me if I bring it by he might be able to get to it in a month, and if he needs parts it will be MUCH longer. Any help? Or similar problems? Thanks in advance.
