54 Mercury electrical question
If you were going to add an inline fuse to any electrical part on this car, 6 volt pos. ground would the fuse go inline on the pos. ground side, or the other side
of the circuit. I am guessing the pos. ground side??? Also, could a small 12 volt fuse box be used on a 6 volt system?? To run lines directly to??

Re: 54 Mercury electrical question
I believe fuses are on HOT items. If its sparks, it is hot.

Re: 54 Mercury electrical question
My Ram dually has multiple switched grounds. To add to the confusion, some fuses are on the hot side, some are not. I suggest you try to keep them uniform throughout the vehicle. My '54 fuses are all on the neg wires, as I am sure yours are. A fuse box doesn't care what voltage runs through it.

Re: 54 Mercury electrical question
In a Positive Ground vehicle of this vintage fuses were in the Negative wire supplying power to the device. Preferably as close to the power source as possible.
Having a blown fuse in a Ground wire may cause other unintended problems as the electrical potential seeks an inappropriate path to ground. Many of the electrical devices are grounded directly to the body (or engine) and there is no practical way to insert a fuse into the mounting. A "12v" specific fuse box likely won't have the current carrying capacity. The terminals & internal conductors may overheat. Wiring and electrical hardware in 6v vehicles is larger gauge / thicker because it is required to handle double the current. . Last edited by dmsfrr; 03-27-2024 at 10:48 PM. |
