[Amps] I need advice on a TL-922 with Harbach Soft-Start module

[Dave G. ve9cb@rac.ca]

Hello all:
I have a Kenwood TL-922 with a Harbach Soft-Start module installed.
Normally, I run my amp from 220vac, but I am currently on a contest expedition in Labrador (Zone 2) and I have to run it off 110vac temporarily while at this location.
I changed the taps through the back panel to run the amp on 110v, and I have bypassed the Harbach Soft-Start module.
My problem is that the fan does not run at all since I did this.  I can't figure out why, and I dare not run the amp without the fan. 
So, what can I do to get the fan running again?1. Can I re-install the 220vac Harbach Soft-Start and run it off 110vac?2. Is there some better configuration of the taps that would get the fan running again?
I am not in a position to test the fan here and now, but I have every confidence that it works fine.  I used the amp on 220vac just a few days before I left for Labrador.  
Jeff W8CQ at Harbach was unable to offer any advice, as he is not familiar with the TL-922.
