Morgan Cars Mid-Atlantic recommends Interstate FAYIX30L. They sent me a new base and longer tie down rods, but the existing ones were fine. The original battery had already been replaced, so perhaps what was sent would be appropriate for the original. That battery was a straight swap
However, The battery still drains. Someone suggested a new rectifier, saying that the Morgan unit was inferior to a Harley. I went to a Harley dealer and he wasn't sure which was the right one. Can someone help me on this?
The HD Rectifier is p/n 74540-01, the ring terminal which connects to the B post needs replacing with a larger ring terminal, apart from that it plugs straight in.
If your charging voltage shows around 14.4v then you existing rectifier is OK.
