wont come on

Try the Shurter voltage selector...don't turn it, just push on the top of it and see if you get power thru to the battery charging circuit.

Yes, with table unplugged from A/C source, excercise the voltage selector switches through different settings then return to proper selection per A/C source. Then check voltage at battery with table plugged in should be >24VDC (~28-30VDC). If not the charging circuit is not operating properly, bad charger, bad power control board, or bad power supply.

Does the table work normally when plugged in to AC?

It did work and then it blew fuses after that. couple days later now just blows

Isolate the A/C plate assembly (power entry w/fuses) by unplugging P17 at the power supply. Remove shrouds and follow the brn/org wires to the power supply, P17 should be near the large blue capacitor mounted on the side of the power supply. If the fuse still blows replace the A/C plate, if it only blows when power supply is plugged in, the power supply is faulty. Replacing the power control board in the power supply could solve the problem but I normally just replace the whole assembly.
