    1966 Buick Wildcat Custom Convertible - Fuse Box Ratings?

    Hi Guys,
    I have a 1966 Buick Wildcat Custom Convertible which is my pride and joy, but today it blew a fuse for the convertible top. The fuse was a 30A fuse, but I suspect it should have been a 40A fuse (the only fuse marked with an amperage rating on the fuse block).

    Does anyone have a listing of the correct fuse sizes for the fuse box? I couldnt find it in the maintenance manual, but I suspect its in the owners manual (but I dont have one).

    The power top circuit is fed by a 40 amp circuit breaker installed in the fuse block. It also feeds power windows and power seats, if equipped. See pg 120-173 of chassis service manual (attached).

    Someone must have installed a 30 amp fuse instead. 40 amp rating is not available in this size glass fuse. Earlier Buick models sometimes used a 30 amp breaker for the power top if power windows and power seats were not supplied. The breaker is self resetting after it cools down, making it much better than a fuse for handling an occasional overload.

    The breaker is a GM part no 1476675. Availability looks good as a reproduction part which was also used on '78 Corvettes.

    Fuse ratings (but not the circuit breaker) are on pg 120-12 of the chassis service manual (attached).

    Wow, fantastic - that's a great help, thanks so much! Judging by the picture I've seen online for that circuit breaker, it looks like it would be too big to fit into the fuse box? So looking at the wiring diagram its a direct fit....

    Yes the contact legs fit down into the clips on the fuse block. The rest sits on top of the block and sticks out like a sore thumb.

    Just came across this picture from the '68 shop manual of the breaker installed in the fuse block.
