[TowerTalk] HDx89MDPL winch motor stopped eorking

[Dick Dievendorff]

What I have heard so far is:

1) I can get the tower down by removing the safety guard and the v belt and turn the wheel by hand. It will take a long time to do this. Down is much easier than up. Be careful. Take rests. Halfway down gives me a lot of strength. 

2) US Towers sells a crank. It takes a long time. I plan to call them on Tuesday fir suggestions. 

3) this doesn't sound like a motor capacitor failure, which would be noisier. There are a couple of socketed timing relays that I should try swapping

I'm away until Wednesday morning, and I'll start on this then. I'll let you all know what I learn.
