  • Hi Friends

    Still not able to get my 1940 Ford 9N running it was converted to 12 volts with electronic ignition, including a coil like in a car and everything was working very good. The starter switch stopped working when pressing the button on the floor so I did replace the push start switch and the new switch still does not turn the engine?? to me I don't think this is the problem the fact the new switch does the same.
    If I bypass the switch with booster cable at the battery ( + at the starter and + battery than - at battery and the other - on touching the frame I am able to get the engine turning and trying to start but only if I keep the cables on with the starter turning as soon I remove my - to the frame the engine stop!
    I took some voltage measurements if the key is OFF voltage at the yellow wire going to the alternator is about 13 volts with the key ON it drop to about 2 volts, now at the coil if key OFF I do get about 2 volts and with the key ON 0 volt???

    your help is appreciated

    thanks
    Serge

  • Sounds like your rod that pushes again the starter switch is worn. Take the transmission cover and replace the rod or Take the switch out , the one connected to the battery cables, and glue a penny or two on it. Reconnect and see if it will start.

  • HiYa Serge-
    First, stop buying new parts and putting them in until you know for sure the old ones are defective. The fact is 99.98% of all the non-starting/non-running issues we read about on these boards are due to some type of 12-volt conversion. The rest are fuel or compression related. Now, there is nothing wrong with converting from the original 6-volt/positive ground electrical system to a 12-volt negative ground system, read how Bruce(VA) explains it –see LINK below. My advice is to next stop trying to jump start it before you do some serious damage until you know for sure what all is involved. Verify the wiring is correct. That means using the correct gauge of battery cables too. If you have lights, disconnect them for now; you can always reconnect them later but take them out of the equation for now. The Pertronix EI comes with its own instructions. Search the archives here for much more info too on EI. Our HOW-TO’s has a ton of info as well, 12 volt conversions aplenty. Go to electrical subcategory and search down tow WIRING PICTOGRAMS by JMOR and download a copy for your shop. Get your battery tested. It must be a good brand that will sustain a charge under load. Your local starter shop or auto parts store can test it, usually for free. Simply connecting your battery charger up to it does not mean anything. Cheap/bargain house batteries have poor life spans and some are bad out of the box. There is so much to consider with the electrical system so begin a step by step problem solving method. I have a hunch you will uncover at least one incorrect issue with your setup. Many 12-volt conversions are done by shadetree mechanics who know little to nothing about the original 6-volt system so they just go ahead and slap a 12 volt battery in and begin to hack up the rest.

  • Re: Belanger
  • Hi Serve, have you tried with just the negative jumped? I have many questions about what you have written but I'll start with this one.

  • Re: Belanger
  • what do you mean by negative jump?
    the way I did was booster cable positive to positive battery and the other end of positive cable to positive on the starter, negative cable to negative battery and the other end of negative short to frame.

    to me it seems like a short somewhere the fact that I have a voltage drop even the way the engine is turning is not as fast as usally???

  • Taken a good look at the wiring diagram in the manuals on this sight. It simplifies the system and will give you a good idea of what could be going on. Take a breather, you can figure this out.

  • My first thought was what if the problem is the negative connection. Just put one of your cables from the -of the battery to the engine near the starter.

  • should it be 3 wires at the starter switch?
