Purchased a portable Airman tire pump from Wunderlich about 1 week ago. Received first one, and it worked for approximately 10 seconds from the bike's power port and then stop. I was able to get it to start a few times but nothing seemed to work.
The next day, I phoned Wunderlich. The guy at Wunderlich said this was the first one he had heard that was bad. No worries, he would ship one out THAT day and it should be there in a couple of days. It arrived this afternoon. Took the new one out and it was exhibiting the same behavior, so I began to further investigate.
I was able to go to the car and it pumped up a ball. I also used another car and was able to pump up my back tire that was low (10 psi). I still will not work on the bike, even if it is running. Any thoughts (other than the fact I might be an airhead on this one )?
I do't know if those have a breaker or something for insufficient amperage, but it sounds like it is shutting itself off. Do you know the power your receptacle can provide, and what the air compressor needs?
Are you using the adapter provided with the airpump and going into a round, auto-type receptacle? Could this also be a sign of reverse polarity? Just throwing out some wags.

Not sure. Just thought that since it had a BMW plug on the end (and is recommended for this process), that it would just work. I looked in the manual and it says that if the battery is low (which it might be, but the bike was running during this process) or too high/low power, it would shut things down. Just trying to see if anyone has had similar issues/problems and might have a solution? Thanks.
Appreciate you posting this, now I am a little concerned about my little compressor I got from Pep Boys...a Slime brand that does a great job on a car tire (six minutes) so was assuming it would do a bike tire pretty quickly...however I didn't really pay much attention to the draw as it said it was made to use from motorcycles, etc. (scampers out to the garage)
I agree with xprof: the accessory socket is current-limited; your compressor may violate the limit. While the limit has been raised (in 2010, I think), the socket turns off with the ignition, which can also be a hindrance.
Just bypass the system by adding a hardwired harness to the battery posts for direct access.

The socket is limited to 5A draw. Any portable air compressor that will actually inflate a tire exceeds that. The ZFE turns it of since it thinks the draw is excessive. A second auxilary socket, wired to a fuseblock is a very good idea for exactly that reason.

I use that pump too. Works great for me. Just hook it up to the battery and it works like a charm. I keep it under my seat at all times.
I have a pigtail direct to the battery for the battery tender. I put an SAE connector on my air compressor for use with that pigtail. Recently, I got a Gerbing liner that, predictably, doesn't like the accessory connector either. I plan to change the SAE connector on the pigtail to match the Gerbing connector.
One more thing, look at Motoport gear ... its a bit pricey, but well worth it! Also, its Kevlar, breathable *and* has all the armor you will ever need. I have tops/bottoms and feel like I have a fighting chance once on my R12.
