Hi, I've one of these panels
fitted to my boat
that seems to have failed. I took the panel back to the dealer who said it was fine as he had tested it. His test was to measure the voltage across the terminals which was around 19.5 volts from memory, he then connected an ammeter across the terminals with no load and it produced around 3 amps. I was very concerned about the test for amps. Having refitted the panel to my boat
it behaves as it did in the dealers but will not actually put any amps out into a load. Is the dealers test valid?
