I have had the same problem after fitting a Trispark Mosfet regulator to my Mk3, after replacing 3 warning light assimilators I emailed Trispark, Steve Kelly replied that the OE style assimilator is not compatible with modern type regulators, in my case the warning light would work correctly when the battery was accepting a charge but when the battery was fully charged the Reg would do its job and stop the charge therefor the red light would stay on, I confirmed this by switching my lights on which placed a drain on the battery.
