no start david brown 885g

i have a david brown 885g 3 cyl gas that has no spark. evey thing is new and still no spark what could cause this?

Try this to trouble shoot the problem. Run a hot wire from the ignition side of the battery to the ignition side of the coil and see if you have spark then. If you do the problem if from the coil back. If you still don't then the problem is in the distributor.

If no spark that way check the wires the ignition switch. And or shorts in the distributor

thanks will try that next

Hello dketcham welcome to YT! The first question is
did it run before all the ignition parts were changed
out? If the suggestion old made does not help then
from there I will suggest this. You will need a test light
for this. Connect the test light lead to a ground, then
use the jump wire suggested by old to touch the probe
to verify the light works and the lead is grounded well.
Now turn on the switch and make sure there is power
to the coil. If so, now hold the probe to the terminal
that comes out distributor and crank the engine with
the starter. You may need a helper to do this. The light
should flash on and off quickly as it cranks over. If the
light does not light most likely you have the points set
so close they are not opening or you have something
touching a ground inside the distributor from when the
points and condenser were installed. If the light stays
on the points are gapped way to wide or they are not
connected to the terminal inside the distributor
correctly. I will link an Ignition Troubleshooting Guide
that another member on here made up quite some time
ago. It will require a bit of electrical knowledge and a
test meter to fully go through all its required steps.
