  • cut-out switch
  • due to a dash fire I am replacing the cut-out, resister, light switch and harness. Should the cut-out can be painted gray for originality?

  • 9N-A gen or 9N-B gen? The 9N-10000-A is a 2-wire/2-brush B-Circuit unit that uses the rectangular voltage regulator. The 9N-10000-B generator is a 1-wire/3-brush A-Circuit unit that uses the roundcan cutout -you can't use one with the other as they are two different animals. The 9N-B genny will have a black slider button on the back plate for 3rd Brush Adjustment and it is marked " HI - LO ". I'd be interested in your non-functioning 9N-A voltage regulator if indeed it is one. Email is open...

  • early 9n Voltage Regulater w/1 wire small geny, took her out for a spin and noticed ammeter was not charging. tapped vr with the wood handle of a hammer. bad decision, went to ground and had a fire in seconds. Figured I would never find another vr so making a bridge & using a cutout.

  • The early 9N-10000-A generator was/is a 2-wire/2-brush generator and uses the rectangular Voltage Regulator specifically for it. It is a B-Circuit design, externally sourced Field. The NAA VR is the same too and will work in place on an early 9N but only if using the 9N-A generator. Your 1-wire unit is the "B" unit, 3-brush/2-wire style and uses the round-can cutout. If it is indeed the 9N-B generator, it will have a black slider button on the back plate for the 3rd Brush Adjustment position, marked "HI - LO". Tapping the AMMETER will not cause afire -you had some bad wires somewhere. Also, if you have a 9N-B generator why are you using a 12 volt battery? There's more to the story we're not getting. Here is all the info you need on the early 9N generators. See how much of yours follows along...

  • Answer first; NO, unpainted. Next, by your question we can all assume you have a 9N or 2N model with a 6-volt generator.You had a dash fire, explain why? I'd be determining the root cause of that first and correcting it. Wiring all caddywhampus? A 12-volt 'conversion' gone FUBAR? Quality parts matter. Buy from a reputable supplier -SEE LINK below. Go to our HOW-TO's forum an download a copy of WIRING PICTOGRAMS by JMOR. These show every CORRECT way to wire these old N's whether 6-volt or 12-volt. Determine which system you have and see what is wrong with yours. I'd leave the lights out of the equation until you figure out what the problem is. Got the I&T F-04 manual and the 39-53 MPC? They are essential in troubleshooting what with diagrams parts listings.
