3 CIM Drive Train Battery Draw

[Brian C]

We ran in our 3 CIM gearboxes over the weekend. Measured with a DC clamp on ammeter the total currrent draw for all 3 motors on an unloaded transmission was 9.2 amps. The funny thing is when checked individually 1 motor was pulling 4.4 amps, the next was at 3.3 amps and the 3rd was at 1.5amps.

When the next transmission was run in we found similar readings as well. The same motor positions in both transmissions had the same basic readings inasmuch that they went from a high current draw to a lower current draw based on their mounting position. The readings only varied by a few tenths of an amp.

After checking gear lash there were no significant differences when run again. These are the AndyMark 3 CIM upgrades for the AM14U chassis..
