Here is a pic of the shorting bar that I removed from the power accessory fuse box location of my 1969 Firebird convertible. I replaced it with a 30 amp circuit breaker. As far as some shade tree mechanic installing the shorting bar, I don't think so. The second shorting bar shown in the pic I removed from a 1969 Firebird convertible in a junk yard. Again, I reference page 12-23 of the 1969 Pontiac Service Manual which calls out the shorting bar. I did a ground up restoration on my car and did not uncover any fuses or circuit breakers in the convertible top circuit. I agree it's crazy if that's the factory set-up. That's why I installed the 30 amp circuit breaker. Finally, the red and green wires from the conv motor/pump are 12 gage. [img:left][/img]
