Bronica SQ and SQ-A issues

I bought a number of Bronica SQ with problems, Cheaper to buy bodies ad get one fixed, So I got an SQ-Ai body fixed with lens cleaned and RB fixed out of everything and am very happy. So no reason to spend money to get the SQ and SQ-A fixed. But the SQ-A works fine but the shutter fires at one fixed speed (lens works fine in the fixed SQ-Ai body. The SQ body worked fine until the shutter speed selector no longer changed shutter speeds. Any sugeestotions?

When there is no power (battery dead, mounted with reverse polarity) the camera shoot always at 1/500th, no matter what speed you select.

Fixed shutter speed is indicative of a dead battery in the body, and/or some electrical issue within the body because only the mechanical shutter-close lever is actuating the shutter closure, not the electrical timing circuit thru the electrical pins on the lens.
