Here is a pic of the fuse, ITS HUGE!

Is there any chance you could post the page 8A-11, the one that has the FUSE/RELAY CENTER as called out in that schematic? It could be useful in diagnosing my problem. I am going to tap into the electrical engineers head at my job on lunch.

Thanks,

Jay

Whoa, time out here. Take another look at the cover under the hood: It doesn't say "RELAY/FUSE CENTER "; It says MAXIFUSE/RELAY CENTER. Those are Maxifuses, not regular ones. They're big suckers, and are not interchangeable with the usual little blade fuses like what you have under the dash.

As for the metal-encased "BREAKER", that is a circuit breaker, not a fuse. A breaker will reset itself after it pops, once it gets a minute or two to cool. They're usually used on high-load circuits like rear defoggers or power windows.

I got cha, it was 10 PM when I did this and I didn not see the 'MAXI' part, I know they are not 'regular fuses'.

I replaced the 30A with new 30A maxi and Before I got to the back to sit on the bumper it blew, and there was a BAD burning smell in the trunk by the passengers side of the back seat. This is where the inflator solenoid is, right? Hope it isnt toast!

Well at least you know the option works.. or worked? Well hope it isn't bad ( i have yet to see mine work, i'm about to go outside to find the pump before I submit to the possibility that my car didn't come with it.. however the fuse box has a fuse for it and i just dont see why they would put in the fuse connector if it didn't have it. i'll also check underhood for more fuses.. however i've never seen a fuse box under hood on my '87,

WOW, this is interesting I always thought that lil compressor was for the inflator in trunk. But it makes since now. yes it does cut on at random. But the funny thing is that I've had my car jacked up for abt a wk with batt connected and I couldnt understand wy my new Die Hard batt is dead but this must be why. Interesting...

Well, here is my conclusion. I think the pump is bad. Here is why. I was working on a prototype machine at work today that has a 170A 240VAC motor on it. The inverter was set up wrong and the motor was not getting enough juice to turn the drum on the machine. The draw went upwards of 320A, and tripped the breaker inside of the inverter. I think this is the same as is what is hapening here. The motor is seized and is drawing hella alot of current to try to move as soon as Iinstall the fuse. The inflator only works when the ignition is on, right? Well the ingition is off when I put the fuse in, so only the ELC should be calling for the pump to work. I know on my dads Buick Estate Wagon that had ELC as soon as the battery was connected the ELC would activate.

i know that compressor is rebuildable... someone somewhere could probably fix the one you have

There is a very good Diesel & Electric Shop that rewinds industial 12V alternators and generators in my parents town, I was thinking of having them do it. Should be able to save some scratch!

The later series ('92 onwards) has the pump under the hood on the driver'* side. Don't know where the '87 has it.

Could be that they didn't do that; I don't know. If you look at the engine photos of '92 and newer, you can see a large rectangular cover running most of the way across the firewall from the passenger'* side; that covers a large assembly of two fuseboxes and about 8 relays.

(I'm getting my evaporator-replacement photos on CD-ROM today and will be posting links to those photos soon; the Maxifuse/Relay Center is shown in several shots.)
