Re: No spark at distributor
If you can't get 6 volts to the OPEN points contact with the key ON, then you might have the cable screwed into the housing too far. It only should be screwed in a couple turns, or three at the most.

Re: No spark at distributor
Thanks- I had the dash hanging loose and still saw the same problem.
I just can't seem to narrow it down to the location of the short or other problem. |

Open the points and place a piece of paper in between to keep them open. Turn on ignition switch. Do you have voltage on the swing arm? Yes - the wiring from the battery, coil primary, ignition switch wiring, o the points are good. The condenser is not shorted. No, Check the above wiring. Once you have voltage at the points swing arm check, with the points closed, do you now have zero volts? Points open 6 volts battery closed zero volts? No, then the points are closing of they are dirty or the distributor is not grounding well to the engine and the engine to the frame, the frame to the battery. Yes, take the wire from the center of the coil and place it near a head bolt. Close and open the points, do you now have a spark 1/4 inch and blue/white in color?

Re: No spark at distributor
Thanks Mitch!
Work and daylight savings keeps me working on it only on the weekend (It's at a storage unit with no lights). I'll keep working at it but I may try you if I take an afternoon off to work on it before the snow flies here. I very much appreciate the offer!! |

Re: No spark at distributor
I forgot - consider buying Les Andrews Trouble Shooting and Diagnostics manuel, best $30 you'll ever spend on your model A! If you are willing to work through the steps, you will learn more than you'll ever need to know about your electrical system. The tips the fella's are recommending are all in Les's book.

Re: No spark at distributor
Thanks all. I got back to it today and I think I just have a bad switch that isn't consistent. I had good voltage at coil, to ignition switch and eventually back to ignition cable. Screwed it into distributor and had voltage at the points swing arm. This is all with the ignition panel unscrewed from the dash so there is not short on the switch. I shut off the switch to put everything back together (ignition cable back into terminal box, terminal cover back on) and tried to start it- turned over but no attempt to start. I checked again and not voltage at points, voltage into the switch (sometimes) but not out to ignition cable.
I think it just must be a bad switch... sound correct?? Thanks. |

Re: No spark at distributor
This is a good quality switch available with or without the cable. It's a look alike pop out..

Re: No spark at distributor
Remember, the ignition switch is on the ground side of the coil, so it will show voltage on both terminals only when the points are open. If the points are closed, then the ignition switch should show ground on both terminals.

Re: No spark at distributor
Finally worked my way back to the switch. When I jumped the two wires at the stitch, I finally got spark at the points. I guess I'll be buying a new switch this winter and waiting for warmer weather to install! Thanks for all of the good advice.
