WebFeb 27, 2008 · 02-27-2008, 10:58 AM. I have an old SA-200 (2365 Code). I cranked it up the other day and it was at idle. I turned the fine adjuster up to 100 and burned the reostat out. I thought I found and fixed the problem ( Temp Gauge tube shorted to reostat). Bought a new reostat fro Weldmartonline.com and instaled it. Same problem engine at idle turned ... Web3. Plugging of dc machine is normally executed by. (a) reversing the field polarity. (b) reversing the armature polarity. (c) reversing both field and armature polarity. (d) connecting the resistance across armature terminals. SHOW ANSWER. 4. A dc shunt motor, running lightly at 1,000 rpm, is operated under plugging.
