[FC] Problem after installing High Volume Blower Motor

[Joel McGregor]

If hooking it up backwards fries the diode then the diode won't be sufficient to keep the system from back feeding as that will also fry it.
Draw a picture of how it's wired, post it somewhere we can get to it and we should be able to figure out what's going on.
I've got relays protecting all the fan speeds on my '65 and no feedback problems.  My relays are the cheapest ones I could find.

> Well, whether it had the diode or not is irrelevant now because when the 85 and 86 terminals are hooked up backwards the diode blows immediately.
