Default ELC

Well i was camping over the weekend with the Bonneville and i noticed something that kind of bothers me... I stored all the firewood in the trunk to keep it dry because we got a lot of rain over night and about every hour and a half the air compressor would kick on for a few seconds and go off again. Now, i know that the wood was a heck of a load all in the rear end, so does this mean i have leaking struts or a leaking airline? also, the weirdest part of it all is the fact that the car was off, key out... i didn't think it could happen with the keys off...

yes, you have a leak, yes, your year the elc is hot at all times. time to get out the listening pipe or soapy water to find the leak. could be at the compressor, lines, struts.

As well, leaky ELC is a great way to kill your battery if you're storing/parking your car for any extended period of time. I dealt with that before new air struts last summer. :(

well i can say that under normal load it doesn't seem to leak enough to cause the compressor to kick in. so it probibly isnt urgent. I might take it to the mechanic my mom took her bonneivlle to. the found and fixed a leaking air line for free. maybe thats all i got, but something tells me its struts... they're old looking.

actually Travis....i also have the ELC and my compressor will come on at times for a few seconds to just keep the level happy when there is a large load in the trunk....i KNOW for a fact that my ELC system is leakless....as i have tested everything before installing

So i guess that with a few hundred pounds in the trunk then it COULD be normal for it to go on like that...

if it would kick on with normal weight then i'd know i have a leak, but it doesn't.

The system works off the switch. If the switch gets low enough to active the compressor or minimum pressure is compromised.. the compressor comes on.

I wouldn't worry about a couple second pump up with this kind of a load in the trunk. The seals of the compressor and other connections would be stressed and more apt to leak slightly.

The amount of leakdown is most likely so minute that you will not be able to easily find it.
