EMS 50C

[Ralph L. Fullenwider]

HI Dick:

Interesting, this is the sort of thing we need to hear about on the Forum.
Most VR's (voltage regulators) shut off when they fail.

In this case, then yes, the EMS hard wired would protect against the over
voltage. Still, so far as I know of it is a rare thing but may induce me to
change my thoughts on the gen set. It is food for thought. Thank you

Safe travels,
