Hi All, I see that Altons are now supplied with a new type of regulator which dispenses with the need for an isolating switch .My Alton is new, but an older type with the older regulator. I am about to wire it in to the loom, and contemplating a switch. To avoid the hassle,is there a straight swap for the new type regulator? I believe its a Podtronics unit, is it a standard shelf item, or a one off for the Alton? Bob.
