Ignition Issues

So after bypassing all the wiring so that i can move her to different parts of the yard and working fine, she now wont start.
I have bypassed inhibitor switch and also the ballast resistor etc as wiring is going to be tackled lastly. So this is a temp made up loom

Things ive checked;
Feed to the coil - good
Feed out of the coil - good (end of wire to Dizzy)
Points reset and filed/sanded down
Points Opening and closing when engine turns over

I bridged the points with a screwdriver and it did spark, however after taking out and cleaning the points it now no longer sparks
I have checked with a light connected to where the wire connects to the spade on the side of the dizzy and it seems that the light is on when the ignition is on but as soon as i turn it over the light goes off and stay off.
I have a book that says to connect the test light to the points or LT wire to see if it does on and off it does nothing.

It looks as though im getting power up until the points. Its battering my head that it was running and starting first time for a goode few weeks an now nothing.

Please help!
 
If the light stays off, then there is no connection between the points and earth, or the points aren't closing (assuming the other side of the test lamp is connected to 12 volts) since the points when closed provide the earth for the lamp.
 
Hi Reece,

Both the original coil and the points are not designed to be used without a ballast resistor. Have you replaced the coil?

Have you done anything in terms of wiring with regards to the starter relay?

we have used a different coil which was working up until last week so if it was working i presume its an unballasted coil.

With regards to the original wiring it is still in situ however i have bypassed it all to get it moving around the yard for now.

So currently i have a live going to the coil, then a wire coming from the coil to the spade connecter. the fat batter cable to the started with another live to he solenoid so the enginer turns over freely.

When i have the light connected to the spade on the side of the dizzy which i assume is the power to the points i then also connect to another earth so i have 2 connection coming from the bulb one to earth and one to the spade. Even if i manually open and close the points there is no change in the light coming on or off.
 
Hi, I'm not sure your are checking anything with the bulb connected like that. Take the wire
from the coil to the dist off the dist and connect to the bulb the other side of the bulb connect
to earth. If the bulb lights you have voltage OK so far, If it doesn't then the fault is in the coil.
Now, leaving the wire off the dist connect the bulb to the dist term and have 12v to the other
side, make sure the points are off the cam, the light should be lit, if not the points are not
earthing, so there is a broken wire to the points or the earth wire is broken or dirty points.
Flick the points open and shut, light should go on and off, if it stays lit check the wire to the
points is in the correct place, between the insulator and the spring. If still no joy take the
condenser out and try again, if that fixes it then the condenser is faulty so replace.

Come back and let us know.

That is a great help when I typed that last reply I was wondering whether I had the light wired incorrectly.

One thing that I have spotted which I may have done wrong which may be a cause. Where the wire connects from the spade to the post where the condenser wire goes to. I currently have it that the plastic grommet thing is underneath the tightening nut which is then going through the condenser end. Should the grommet actually be underneath the condenser connector and go through the dis wire connector?

Cheers again for the help!
 
Hi, going from the top should be the nut >plastic insulator >wire connections > spring >plastic
insulator.

Ahh i seem to be missing a plastic insulator then as i only have one which goes through the top of the condersor connection and possibly goes a little through the coil wire seem to be missing the bottom plastic insulator.
