Ford F-1540 Questions
#4

Power the radio with a full size auto L/A battery. Use at least #12 wire at 5 feet or so if longer, say, battery on floor, use #10 wire. The battery must not be on a charger and fully charged. When testing be sure all covers over the vibrator circuitry are in place. Use the low capacity cable for the antenna and be sure its shield connections are good route antenna cable (coax) well away from the two power cables, in fact, twisting the power cables will help reduce any errant vibrator hash. Using just a wire inserted into the antenna jack will result in hash.

Most often the Buffer condenser has or is failing. Use the same ratings, the new cap must have a buffer rating or a posted dv/dt rating or it will soon become defective if the wrong type. All bets off if a solid-state vibrator is used, but shielding must remain.

The vehicle may not have RFI protection to support a radio. That is another topic...
