As said previously I have had the same problem on an MD80. Taxiing out noticed strobe lights were flashing, couldn't get power below flight idle but did not notice RAT temp or know TOWS was inop. I was able to fix the problem with aggresive brake application to compress the nose gear strut. Everything returned to normal. I then got in the maintenance books days later, and found out the air/gnd sensor on the nose strut was saying I was in air mode. I am smarter now and know the TOWS that night also was inop. That R2-5 relay or whatever was in air mode along with the TOWS. I didn't know it that night. I did have the flaps set but if I had not I would have had no warning. I don't think it would have ended up in a crash but it would have required more runway. Rotating to a normal deck angle and waiting for the aircraft to fly works for most airliners, over rotating can get you a tail strike or if in the wrong configuration, much worse.
