Thanks Richard, What you have said is pretty much what I thought was the
case. I have been hoping that Dennis might have something to say. I will
try what you said to see if that works. The excellent working of the
heater does make me wonder about the coolant actually being low, but I
suppose it could be low enough to cause the blinking on that occasion
without being low enough to prevent adequate coolant flow to the heater.
It's a pretty cold day here today, teens F, so I may wait until its a bit
warmer, as my garage isn't heated. Oh, I also don't have the hose clamp
pliers for that hose on the pressure tank. Any ideas (or anyone else know)
of a way around that for those clamps? Where would I get that pliers?
