Crown SP3020-30 Serial # 1A1718xx
Lifts and lowers, but will not move.
Displays wrench symbol and GATE on display.
Seems to power up fine. When I try to go forward or reverse, it displays BRAKE. I step on the plunger to release the brake. I then try to go forward or reverse, it displays GATE. Side gates are down. The tow/drive switch is in drive. When I move it to tow, I see the brake on the motor move and and hear a click. When I step on the plunger to release the brake, should I see and hear the same thing that I do when I move the tow/drive switch to tow? Under normal operation when should I see the brake on the motor release? Any ideas what happened? Previous owner said the battery died and he parked it. On the display the LAST=208. I assume this is an error code....

Thanks,
