I wonder if that "putting" noise you hear is because of the valves. Could be they just need adjusting. And then, again, we have I believe had folks tell us here that that noise is normal in a jeep.
I use the "original" wiring that is available from Ron. Works fine. As far as shielding the radio? I bought one of those huge capacitors that goes in line before the radio and that seemed to do the trick for me. But at present I am using 12 volts, electronic ignition and an alternator. Oh, the sin of it all.
