The Hoosier Mets caution you when you do this change.


Many Metropolitan owners have converted their cars from the factory original
POSITIVE ground to the more standard NEGATIVE ground electrical system.
With this conversion, you may add an FM converter, plug items such as
Cell Phones, CB radios, and accessories into the cigarette lighter without ruining your electronics.
Others have added cd players under dash stereos to their Mets.



This tech tip was originally published in the
Metropolitan Owners Club of North America's newsletter
The Met Gazette

Switch the wires at the coil.
Turn your battery around and connect positive cable to positive post on the battery.
Connect the negative cable to the ground.
Get a wire long enough to stretch from the battery positive to the engine compartment.
Have someone hold one end of the wire (with end of wire exposed) to the positive post on the battery.
The 2nd person take the other end of the wire (wire exposed) and brush it against the "F" (field) post on the voltage regulator until you see a few sparks.
You are now converted. Check all your fuses to see if any blew out, and if you had gauges, you will need to reverse the wires or the display will be backwards.
You can now connect an fm converter, radio, and plug stuff into the cig. lighter without ruining your electronics.
