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).

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.
