Seneca torubles

[Keith Rowland]

Everybody and Aaron:  I would agree that the relay needs to be
replaced.  That was my first thought when I saw your message earlier
today, but I was doing some research to see if I could come up with some
other explanation.  The only other thing I can think of is low voltage
to the relay coil.  You might check that first, because I know what a
pain it is to find the right relay...not to mention replacing it.

73, Keith
