Re: (ET) blown relay...

[jim <fiskfarm mediaone net>]

I was away during this discussion but I may have some different advice on
this. I found that water gets on these relays if you leave your tractors 
out
in the rain and if you run them before they get a chance to dry out: POOF. 
I
lost 2 in one week. My fix was to run a strip of foam weather stripping 
across
the dash cowling just under the hood. I remove their rubber feet off of the
hood first. Haven't lost one since as it channels the rain off to the 
sides. I
did all my ETs this way. Someday they will all have their own shed! I 
promise.
