100a is about right for blowing snow. I don't have a shunt on that line specifically, but 300+ amps would include the drive motor shoving the thing up hill.<span class="m_-6394532560778333582HOEnZb"><font color="#888888"><br>

They were Prestolite contactors. I have the spec. sheet. The Normally Open contacts are rated at 100 amps and the Normally Closed at 150 amps.<br>
Doesn't seem right that the NO are lower than NC but the NC are Silver and the NO copper.<br>

I just wish I could find some kind of GE document or other resource that<br>
actually stated the current rating of these contactors.<br>
