Afternoon all,
I've been digging deeper into a problem i wrote about about a month ago.
My faucet has lost its get up and go...

After dismantling the Shru-flo, making sure that the values and all tubing
were free of restrictions and checking the wiring for defects, I made the
jump and bought a new submersible pump which i installed last week. Still
no flo...

I can hear that the pump is trying to do something - there's a faint hum
coming from the tank
when i turn on the faucet.

I have a gowesty auxillary battery kit mounted behind the driver seat and i
can hear a distinctive "clunk" coming from the isolator when i turn on the
faucet. I dont recall this clunk before I started having problems with the
water.

I assume that the amount of power required to run the pump is the 12v.
I'm only measuring 3.5 volts when i flip the faucet on.

Any opinions on whether i need a new 2nd battery relay (the original to the
van as far as i know) or has the isolator gone bad? both?

thanks!
