Model a ignition problem
After sitting for 4 years, I attempted to fire up my restored 30 model a pickup. It turns over and has spark at the points, but no spark going t,o the plugs, hense it will not fire. Any ideas? I also replaced the condenser thinking that might be the problem. The positive ground strap seems warm when cranking it over.

Re: Model a ignition problem
closing the points grounds the circuit back to the coil red wire.. when opening and closing the points the red wire at the coil should flash using a basic test light.. i would clean the points better to make sure they are giving you a full ground,,, they do get oxidized from sitting. then ck for spark directly from the coil wire to a head nut.. you can do this by opening and closing the points manually with key on... i would also clean the battery ground cable connections at both ends that are getting warm...

Re: Model a ignition problem
Ok, thanks, I'll give it a try. Could there be a short if I have spark at the points?

Re: Model a ignition problem
the points are supposed to spark when opening and closing //key on...as mentioned clean them first
ck for a blue spark at the coil wire holding it 1/4 from a head nut Last edited by Mitch//pa; 07-23-2015 at 04:19 PM. |

Re: Model a ignition problem
I had a brand new distributor sitting in my motor for maybe 4 years before I tried starting it.
There was no spark at the plugs and when I tracked the current, it got as far as the points but only to one side when closed. A film of corrosion had built up on the points and when lightly sanded, the motor started immediately Keith |
