72 circuit breaker at terminal block
« on: September 14, 2010, 11:57:59 AM »
The 1972 wiring diagram shows a circuit breaker installed at the terminal block adjacent to the starter solenoid. However, the circuit breaker feed only convertible top, heated back glass, power windows, and seat back latches. This car has none of these options. The question is, should the circuit breaker be there or not?

Thanks, Chuck

Chuck,
Without those options my opinion is that there would be no draw on that circuit to require circuit protection.  My car has bot the heated rear glass and back seat latches so I do have the breaker.  I am by no means an electronic expert, but Midlife on the forum may have an answer.  He lists to specialize in first generation wiring a dash harness restoration.

Sorry, but I don't have any insight into the 1972 underhood wiring options, given the car the Original Poster describes.  My intuition tells me that without a reason for a circuit breaker, there wouldn't be one.
