330 America Ammeter

Spring is in the air, and I haven’t done anything to my 330 America this winter! I’ve been so busy that the last long trip I did with my car was last September when I took it to Watkin’s Glen for the Ferrari Club of America International Meet.

It was on this trip that my ammeter stopped working, and the car stopped running completely. Early Ferraris run all the power besides the starter through the ammeter and if this gauge fails, nothing will work. Luckily, I could still reach the back of this gauge, so I simply put the two wires on either side of this gauge together on the same lug, and I had power again. I love successful roadside fixes!

With spring fast approaching, I pulled the broken gauge and sent it to John Wolf Company in Ohio and he turned it around pretty quickly. We talked a little bit about this gauge, and what broke inside. John explained it simply overheated and burned a wire inside the gauge either from too much current, or simply through wear and tear through the years. I don’t think I ever sent this particular gauge out for restoration so it may have broken from age. John also told me despite this gauge reading 40 amps at its maximum range, internally it wasn’t built to handle that much current. Short charges of 40 amps was probably OK, but a longer duration would probably burn it out again. All this data was good for us to know when we let our batteries run down and make our alternators do the charging!
