Last haulout my zincs were gone and lead keel had pushed off paint a along with epoxy bottom. I had lost two raw water pumps before it finally hit me. I checked with a good quality multimeter and read 6.5 amps when going from a known ground and touching other probe to raw water pump. The only thing I have changed is adding a new radar. It is freaking me out. I installed a new zinc saver on the shore power neutral but dont know how to best isolate the issue. Any ideas would be greatly appreciated.
