Ground conversion

[KENS TR3]

When you convert 59 year or three to negative ground, do you have to change the voltage regulator?

No, it should work both ways if you have the old electromechanical type. They do have points type contacts which apparently used materials that would last longer if the electrons are flowing the right way, or so I have read.

...and I believe you should change the small wire connection between the coil and distributor. It still works either way but "they" say the spark is stronger if connected properly.

Swap the coil wires and re polarize the generator if it is a positive earth system now

Anyone remember Randall Young? I kept this from when he posted it years ago.

"Note that you don't have to actually change anything on the generator, just repolarize it. One easy way is to disconnect the wire from the F terminal at the regulator (ignition off, engine stopped), and brush it against the A terminal. If you see sparks, the job is done."

The amp meter will read backwards if not reversed , but the rest is EZ PZ.

Amp meter is easy too, swap big wires on the back of the gauge, disconnect battery first, as I believe the circuit is hot all the time.

And if you hate smoke, adding a fuse able link in the large brown wire can add a lot of piece of mind,
