Converting a 220 Volt Indiana Jones Pinball to 110 V USA power

[rugby1]

I currently live in Germany and bought an Indiana Jones Pinball machine here.  Its 220 V.   I will be moving back to the States at the end of the year.  How do I switch the pin back to 110?  Is it simply replacing the Power Supply (under the playfield) to a 110 version? and the 2 pin German plug to a US plug.   Is there anything else that I need to do?

Thanks

A lot of power supplies have a switch on them to go between 110 and 220. You may need just the power cord.

I looked at that, but didn't see a switch on....  I highly doubt that it is an auto-sensing power supply since it was made way back in 1993.  It has connectors similar to molex connectors on your cpu power supply, so not really anything to rewire, just a matter of swapping the psu out.   I don't know if I can use any old 110 power supply or not though

There's a Molex jumper plug in the wiring harness next to the large power transformer in the bottom of the cabinet. You'll need to get a Molex pin extractor tool (Radio Shack # 274-223, about $5) because you will be moving some wires from different holes in the connector to reconfigure the jumper plug wiring from 220-240 volt operation to 120 volt operation. The jumper plug configurations for various power operating voltages is shown in the schematics manual on the "Power Wiring" diagram.

It's fairly easy. Just look in the manual for which wire to move and move them from one set of holes to another. Generally only 2 wires get rearranged.

so you are telling me its just a matter of switching some wires out?  no need to replace the whole power supply?  that would be very very good and easy   

I'll pull the manual out when I get home later

Thanks

Nope you don't even touch the power supply. Everything is done down by the transformer. Just swapping wires on the jumper connector is that's required to configure it. If your machine has a computer/office machine style plug-in power cord then you also unplug the European cord and buy a regular USA type computer power cord and plug it into the back of the machine (after removing the black cover plate on the rear of the machine).
