Powermaster links?

Anyone have a link to troubleshooting the Powermaster.

The brake light flashes on when you hit the brake. Only for a split second. Pedal still feels okay. Pump runs, and shuts off.
Is it the Accumulator?

Likely it is the accumulator. But first check all your grounds and power connections with the troubleshooting tree. Make sure you have good connections. If it still does the same things, I think you are on the right track with the accumulator. This is a mirror image of what happened to me, including resolution.
