I need a shunt resistor which is behind the fuse panel of a 1917 & 1918 and possibly other years of the Maxwell. This is for a 12 volt system. Does anyone have the info such as part numbers, number of windings, type and diameter of the wire used and or the wattage rating and the resistance? Any and all info will be appreciated. I have books showing all types of wirewound resistors that are still available but I need to know the wattage and resistance and then I will be able to share the address and part number for Maxwell owners to order new shunt resistors for there cars. I also need an ignition key or a pattern for an ignition key to build one for my car. All info and help will be appreciated. My email address is Kenscars@comcast.net
