Working on Attila the Hun and I get a constant blink on the MPU. Power supply has new bridges and all test points are correct.

MPU test points are:
J1 pin 3 - Connected - 15.5 V
               Unconnected 27 V
TP1 -    -7.27 v
TP2 -  -9 mv

I didn't even take any more readings as something is obviously out of whack.

What on the MPU will drag down the voltages like that?
