Problem Power feed will not work.
Found The Power feed fuse Blown.

Replace fuse, activated Power feed - Fuse Popped and Smoke from the Power feed motor. :eek:

Fixing the Power Feed Motor. Started with this video.


Findings
Commutator needed turning, Brushes worn badly. Bearings need replaced, Cracked and missing wire insulation. Burn marks on housing from shorted wire with missing insulation.
Fix
Filed the brushes flat.
Turned the Commutator
Cut the Mica, back below the cooper surface. By turning the tool 90 degrees and advancing the carriage for each segment.
Installed wire shrink wrap to hold the old wire insulation in place on the field winding leads.

Note;
1st use of HLV-H - Turning the Power Feed Commutator

Try it again
Replaced Fuse, the Power Feed ran, but NOT adjustable (at least the motor did not short out again. fixed)

Trouble Shooting the Potted Rheostat
Could not make any since of it. - Someone FIXED it before.

Ripped out the old potted Rheostat and replaced it with a New $60.00 IRONHORSE Model GSD#-240-2CL / DC Drive Made in the USA

The DC board was very easy to wire. Followed the instructions for a shunt motor. Very easy

I had to study the different Allen Bradley Contact Blocks - To wire in the AB Switch. I kept the original AB Cam and replaced the contact blocks so I could understand the system.
