Hello, I have a 2005 Tahoe and the remote positive terminal, where the fusible link connects off of to the alternator has begun to melt the Red plastic. The fusible link has not broke, I have recently had trouble with the igntion accessories only coming on when I tilt the Wheel up and down. The vehicle has about 130,000 miles on it and was a former michigan oakland county sheriffs vehicle. I am going to begin by replacing the battery cables and replacing the worn fusible link, suspecting that the harsh winters here in chicago have dirtied up the cable connections. Also I am replacing the brackets that support the positive cable that wraps below the engine to the starter. I bought the vehicle used and the supports for the cable were taken off. My assumption is stress on the cables have made the connections loose/highly resistant over time. I have also recieved a couple of time the "service charging system" message onn the DIC! I have a couple susspected areas where there could possibly be a short or bad ground for the headlights, which I am going to fix if needed beforee replcing links and cables. What could I be missing? Does it sound like I am on the right path.I have been researching al over and cant go ono with out my truck!Hah Ill be awaiting your reply
Thank you for your time

Where this was a police vehicle, start by looking for things they forgot to remove or disconnect before it was sold. GROUNDS are major and bad grounds can cause overheated circuits. Also GM had problems with the connectors under the driver's seat, unplug it and check for corrosion in the connector, clean it out with electrical contact cleaner, and put some die electric grease in the connector before plugging it back in.
