Just bought a boomchair SVC and the rumble on it will not turn off. Any ideas?

Here's a link to the Service Manual:

engine or gearbox mounts

I need one too. I found the owners manual on-line and it says the AC/DC Adapter we need is 12volts and 2500ma (2.5amp). I wrote to the company to see if one is available. If not, I may just try to find one that matches the voltage and amperage, cut off that odd male end and wire it directly. the only issue will be finding the positive and negative.

Look on a website for a new one/ go to the manufacturer's website. You should be able to buy another one.

if you have rough terrain tires on that could be a cause

Boompods are made by LumiSource, the maker of Boomchairs. How to hook up your chair to most devices are on the www.boomchair.com website. The Boompod is made to play primarily hand held games, like PSP, Nintendo DX, etc. But you just need the audio cords with the red and white RCA jacks on both ends to hook up to your TV's audio output. Go to a Radio Shack and they'll hook you up.

Check for broken tire belts. Make sure your front struts are secure. Rebalance tires. Also clean any mud stuck to tires.
