NSX air pump

[Vytas]

Today I was filling up air in my daily driver GSR using the NSX air pump. I ran the pump about a minute for each wheel (inflates about 6psi/minute) with about a minute or two on non operation as I went to set it up for the next tire. After I was done with the last tire, I pulled out my GSR's spare tire which had 32psi and needed to be at 60psi. I label on the pump stated not run it for no more than 15 minutes continuously. I ran it for two minutes and it stopped. I thought it just may have stopped automatically to prevent it from overheating. I took my bike pump and inflated the spare to the right pressure. About 10 minutes later, I plugged the NSX air pump in the cig lighter and it still didn't operate. My guess is that it requires more than 10 minutes to cool. I'll check it in a couple days. Wonder if it broke. What do you think?

Check for a blown fuse too

where is the fuse on the air pump ??

Lud is probably talking about the fuse in the engine compartment fuse box. It's a 20A fuse and is fuse number 15 on the circuit.

Actually, I was using the NSX airpump in my GSR's cig lighter. I know my GSR's cig lighter works since I used it to power my GPS unit with no problems. I'm away from home but when I get back I'll give the NSX airpump a try. Hope it was just an auto shut-off to prevent damage.

I had a similar problem using my NSX pump on my other car. I'll check it later today -- hopefully its also an auto shut-off.

I checked my cig lighter on my GSR today and it wasn't working. In my previous message, I stated that it was working which wasn't the case. My GPS was working off it's batteries until I got a low battery warning which surprised me since I had it powered by the cig lighter, so I thought.

Checking the cig lighter fuse under the dash, it was indeed blown as Lud suggested. I replaced the 10A fuse and checked the NSX air pump and it works fine.

For a while there, I thought I had lost my air pump.

I inquired to a friend about the NSX air pump stopping and here's his take:

As the pressure in the tire increases the electric motor has to work harder to keep pumping up the tire. This forces the air comp to draw more amperage to keep up with the increased load. The fuse blows because the load exceeds the fuse's capacity.

That makes sense since I've been using the NSX air pump to fill the tires on my NSX and GSR. The pressures never exceed 35psi. Since I was filling my GSR's spare tire which needed 60psi, it had 32psi and I had it running until it quit at 46psi. That was when the fuse blew. I'll just fill the spare tire at a gas station or with my bike pump.

I find the NSX pump almost useless. I have tried to pump up the NSX tire when it was low once, it got so damn hot!!!! I would rather not use it if I don't have to for $600 retail you think you would get something better. (I may be off on the price this is just from memory)
