  • Alternator replacement
  • I have an 49' 8n with a 12V conversion. The alternator just went bad (had it tested). It's was a single wire conversion. My question is, I have a two wire plug type alternator off a parts tractor that is good. Is it possible to wire that one in with the old one-wire harness? If so, how?

  • You can also make the regular Delco 10-SI into a one-wire by installing a one-wire regulator in it. ....but I guess everyone knows that?

  • Just for sake of argument because I've read both sides of the story, but when one does a 12 volt convulsion, should they replace the ammeter with a voltmeter? Seems you would still want to see amps being charged. Anything wrong with wiring both an ammeter and a voltmeter?

  • Some like one, some the other. Both would at times be useful, whether generator or alternator.

  • I've had bad luck with one wire. Also the lamp a big help. I mounted a trailer side marker just by the ignition switch. Now when the light goes out it's charging. Not to say the one wires are bad.

  • Yes. With plug at top of alternator for reference, loop the #2 (right side) pin down to the output stud.

    Connect the #1 pin through a diode, resistor or lamp to the output of ignition switch.
    Device in the line is to prevent the engine from continuing to run when switch is turned off.
