Alpha Dead,will not power up. took it apart, could find no obvious problems. suspect problem on the electronic card.
(tongue in cheek). That ended up about where you are on that Alpha.
Couldn't find anything wrong!
Voltage was getting to it, right? As in, throught that quick connect cord on it? Check and make sure you have continuity through the cord and the plug connections with a multi meter if you know how to use one. I hope it's something simple like that....
Have you been able to get the circuit boards free in order to get a good look at them? I think most of the real estate on those boards is taken up by resistors and diodes to operate the multi speed feature. There should be a power supply on one of them which should be looked at first.
Never got in there yet. I tried. there is two little squeeze tabs in there that are very hard to get something on to be able to release the cover from the board
