Re: (ET) Totally dead E20, thoughts?

[Max Hall <maxmatic gmail com>]

I think this is exactly what happened to me: a fused contact on the reverse
relay.

If I have it right, it looks like it's changing state (the relay moves, and
ONE of the two contacts is changing state) but if you look closely at the
contacts on the relay, you'll see one of them melted to another.

Here's hopin' (because it's a pretty simple fix).

And, so that you don't wind up with forward as reverse the way I did, be
sure to note your connections well before you take the relay out to work on
it....
