Dear All, some advice please. For some time I had been thinking of converting my Humber 1 Ton to electronic ignition using the innards of a cvrt distributor. Now that the Humber is gone, I have replaced it with a Ferret I would like to test out my theory. With a spare distributor base I have swapped the electronic module into it, lengthened the cables and am preparing to swap it in. I’m pretty sure I can run a second lead inside the screened cabling from the ignition junction box, through the filter into the coil to join with the red cable coming back from the ignition module. This second lead provides the 24 volt supply to the module and will be taken off the terminal in the junction box, before the ballast resistors.
My question is do I need to Earth the black lead from the module which is the limiter circuit for the ignition or can I do without it (rumour has it the Army often used to take the fuse out (isolating it from earth) to prevent the limiter circuit operating anyway - at the risk of overrevving clearly. ) I don’t think I will be needing it, in any case it would be set to high for the B60.????
I don’t think using the ignition module in reverse will be a problem.
Anything I have overlooked? If it doesn’t work I will simply swap the original back in.
