Sounds like I have the same firetruck too. Mine is a 54 630 with the 503 but mine came with two 6-volt batteries and negative ground. Is this therefor 6-volt everywhere? (lights,etc) or 12-volt. I have a new 12-volt 0ne wire alternator installed but haven't connected the wiring yet as I'm not sure how to hook it up. Thanks, Ron.
Also mine has the disc break e-brake setup. Does all three of yours? I want to get rid of the fire apparatus too, but what do you do to hold the e-brake in place cause the disc is mounted to the fire pump?
