[FLYNAVY30]

Unfortunately, I've been replacing them at my expense over the last decade. Their warranty process is painful and cumbersome, though at this point, I wish I had made the effort.

For what it's worth, I just dropped the positive probe from my multi-meter into the coolant in the reservoir, and grounded the other probe to the battery. I'm showing .2 Volts. I dont know if thats enough stray voltage to eat the aluminum welds over time, but it's definitely there, and I have no idea how to chase it.

I havent pulled the zinc anode yet as the mosquitos were getting unbearable out in the driveway. Ill take a look at it tomorrow.
