Elan & +2 Elan use different motors, the Elan uses a 2 wire motor the +2 uses a 3 wire motor.
I don’t know if all + 2’s use a 3 wire motor as this type is more often found in older vehicles where a two directional operation is required. I think this is why people report improvement in operation when the ‘ earth ‘ connection part of the circuit with 3 wire motors is upgraded.
When the permanent magnet field motors arrived, that reverse direction simply by changing the polarity of the applied voltage, the power hungry an heavy 3 wire motors were dropped.
Re, Window Motor Current, the total friction within the system has a significant effect on the power required for operation. I found a big difference in the current drawn by a motor just by a clean out and old grease replaced. Friction caused by old operating cable that has become stiff should be replaced by new highly flexible multi-stand Stainless steel, in my opinion the stuff supplied by usual sources can easily be surpassed. Correct size glass runner felt is essential, half a mm too small can make a huge difference in power needed and speed of operation.
