Re: (ET) 24V relays



Interesting. However I'd bet that the E12 has 1hp, E15 has 1.2, and E20 has 1.5, right?

That said, the E15 should be fine for leaving outside to deal with the snow and all.

   It's copied from an Excel spreadsheet so the columns may not line up
right but you can get ratings from it.  Mower motors included.
I have an E15 and E20 and not sure there is any noticeable difference.

Or you could just get a 36 volt relay. I have those big ones with the
plastic caps; you can take out the bottom screw and put in a sheet metal
screw then mount it up in the tractor. So far I have not had one burn up
(although I have seen them with burned contacts in the E15 junk parts
box that came with the tractor).

So yes, even a really good relay can be eaten on an E15. The question
remains as to if the mov can protect them; once I get my battery box
I'll drive the E15 for a year and find out.

Speaking of which, how much less power is there in an E15? I'm thinking
of parking it on the driveway with the snowblower attached this winter
instead of the poor little E20 (who likes the nice dry shed). Can it do
the "blow 2.5 feet of thick wet snow) with chains and weights? Or will
the motor overload (the E20 can do it, but man it pulls a lot of power).

Chris
