Your generator/voltage regulator will not work properly. What is the reason for change?

Possible but expensive. The big problem is the radio. It is possible to replace the regulator, polarise the generator, switch the leads on the coil, and the light bulbs don't care one way or the other.

O ya your horn will suck not blow ha ha just kidding about that last one.
