Ok turns out an accessory that the last company installed; the wires were pinched on one of the cylinders and shorted out.
Changed the fuse and everything is OK.
I get beeps upon startup now and shut down. I think the startup beeps show -02 on the display. On shutdown I get 4472 and the hourglass and tire with motion lights go on, then I get 2710 and the hourglass and lift lights.
