![]() I once had a cluster of wires overheat and fuse together, but this completely drained my battery overnight. In my opinion, either the stereo is installed incorrectly, or you have some other short in a wiring harness. They will automatically reset after so often (so you don't have to do it manually like the breaker panel in a home). Sometimes electronic devices have a component that act like a circuit breaker and trips when too much current passes (called an MCB). In my opinion, this wire is not connected to the right thing, so when your dash lights kick on, the stereo is shutting off as a safety precaution. This is for the illumination of the stereo display to change with your dash light brightness. In the harness that connects the stereo to your speakers and accessories, there is also typically a wire that goes to your dash lights. Given that your radio works with the headlights (which will draw significantly more power than the radio does), I doubt that is happening. There is absolutely no reason any sort of "power surges" or "redirects" would take place if it is wired correctly, unless you also installed a high power amplifier or something else that the alternator cannot generate enough current to keep running. Stereos typically need three power connections: Always On 12V (essentially, straight from the battery with an inline fuse), Accessory (12V Only when key is on), and Ground (to the car chassis). Who installed the stereo? How do you know it is wired correctly? Well, this doesn't have anything to do with the instrument panel cluster, but I have done a bit of work with stereos and other auto wiring harnesses. Don't forget to reconnect the battery cable! If it still doesn't work right, then there is probably something else more seriously wrong. You may want to test it out before you put all of the dash back together as well. When you are satisfied, put the panel back together and put it back in the car. Four parallel 150 ohm resistors should have an equivalent resistance of 37.5 ohms. When you are finished, you can use a multimeter to check your work. Don't worry if you accidentally bridge them together (like I did), they are all in parallel anyway. ![]() Then, attach the resistors one by one where the old ones used to be. Clip the leads and fold them over before coating each lead with a bit of solder. Through hole resistors (Color code: brown - green - brown - gold/silver) are fine. You will need four 150 ohm resistors (1/4 Watt) to replace the old ones. Then, add a drop of solder to each pad to prep it for the new resistors. Remove the resistors and clean off the pads with rubbing alcohol. You may notice that one or more of these resistors is crumbling or has come off of the board completely - this is the reason the circuit isn't working correctly. They will not look like typical resistors, but more like metal cylinders. Locate a group of four resistors in the upper right hand corner of the circuit board. With the case completely removed, you should be able to see the complete circuit board. The screws and plugs will all be on the under side of the dash, so get down there and get to it! Try to only remove what you have to in order to get to the IPC, and don't lose any of those screws. A good idea is to start with the small pieces on the sides of the dash (what would be up against the inside of the car doors when they are closed, and work towards the large dash pieces from there. These can be tricky to remove with a plug puller, but you should be able to pry them out with other tools. The other thing in the way is all of the carpet pieces used to cover up the mess of wires below the dash. Removing the bolts allows you to slide the pieces out. Most of the plastic pieces are slid into place on one end and bolted at the other. ![]() To remove the IPC, you will pretty much need to dismantle the entire dash compartment. It is held in place by a couple of screws, but getting to it can be a challenge because of all of the other dash board parts in your way. The instrument panel cluster is the collection of gauges sitting behind your steering wheel. ![]()
