What I've learn on many years of working on Raymond is Q1 and fuses don't blow because they are old, so something is taking it. I'll give an example. I had a technician 3 days working on a code 26 and after 3 days I pass by and found a small cut on the motor cables touching the ring loop. You could pass your hand and you couldn't feel the cut. You had to actually bent the cable to see the opening. This tech replace power cards and TM. He was about to order a motor before we took a look at it. So if your Q1 is bad make sure the diode is good and the motor. Also if you take out S1 cable and ohm meter the cable to the frame it should be open that how I test the block on the Q1. Best of luck.
