Yesterday evening I spent a few hours pulling the gas tank out of the 1989 Convertible. Since this is a 1989 car, it has the gas tank under the floor of the trunk and the filler neck comes out the side of the vehicle on the driver rear quarter panel, just behind and above the rear wheel. Once I got the tank out I was surprised at the size of the tank. According to the replacement tank for a 1989 Caprice sedan, it is 22 gallons. The other thing I was surprised at was how the Avanti plant had modified the original Caprice tank to fit into the 1989 Avanti Convertible. Here is a pho

I pulled the fuel tank this evening. Once it was on the ground, I decided I had enough for the day and came home to make pizza.

No, the small diameter piece of wire is actually supposed to burn through. See the following article on fusible links: https://itstillruns.com/causes-fusible-blow-car-12161001.html When it fails it should look something like this:

I spent another couple hours working on the dead circuits issue on the 1989 convertible this evening. Here are some photos showing what I found when I pulled the wiring harness away from the starter solenoid. Other than the main positive battery cable these are all of the wires that are normally connected to the positive supply lug on the starter solenoid. These are two photos of the main positive battery cable that was connected to the positive input on the starter solenoid. The green corrosion on the cable lug and the rust on the starter terminals do not look very

This evening I finally went over to my shop to investigate this further. I ended up unbolting the starter from the engine block so I could completely disconnect the whole wiring harness from the starter. After doing that and disconnecting a single wire going to a sender (oil pressure perhaps) on the side of the block near the starter, I was able to pull that complete section of the wiring harness up from below the engine to the top of the engine compartment so I could examine it and work on it much easier. I found that there were three 16 gauge fusible links and one 12 gauge fusible link conne

Yeah, replacing with a real fuse seems like the way to go. Do you think a 30 amp fuse would be appropriate for that location?

Does a fusible link have a particular rating like a regular fuse or circuit break that determines under what load it will melt?

Based on suggestions from IndyJIm and looking at the power distribution wiring diagram he uploaded recently I have come to the conclusion shown below based on the list of dead circuits I have in my 1989 convertible

Thanks Jim Which specific plug through the firewall are you talking about? I do see what I think is a large bundle of wires in a "plug" like structure going to the firewall but I have not figured out how to "unplug" anything there to examine the inner workings of any connection.

I have posted here before about some issues my 1989 Convertible has with various electrical subsystems that do not work. Briefly the list is: Things that work: starter gauges hazard lights & turnsignals brake lights power windows power top motor (I can hear when working the switch but I don't know if it actually raises or lowers the top) Things that don't work headlights taillights reverse lights gauge lights trunk release gas lid release power seats fuel pump I have continued inve

Just thought someone might find this photo useful for ID'ing which fuses are which in the fuse block buried up under the dash on my 1989 Convertible If anyone is interested I have a higher resolution version of this same photo.

I cleaned as much of the undercoating off the wires going to the fuel tank on the 1989 convertible so I could try to identify the wire colors. This is what I ended up with:

I will try cleaning the undercoating off the wires and after that I will try to get a friend to help turning the key while I am under the car checking for an electrical signal. Thanks for the hints on the wire colors.

The 1989 convertible with the throttle body fuel injection has an in-the-tank fuel pump. I want to see if it is getting power when I crank the motor but I have to know which wire does what. Here is a photo of the modular harness plug going to the fuel tank. One wire is red and another wire is a lighter color and the third wire is too obscured with undercoating to tell what color it is. Anyone know which wire does what?

The front fenders on both my 1989 convertible (shown below) and the 1988 coupe both show evidence of cracks at the top of one or both fenders. The fenders on the 1988 coupe are much worse than this.
