Technician: Curtis B., Technician replied 6 months ago

It has spark? Or no spark? and will not fie on starting fluid? What is compression?

Customer reply replied 6 months ago
It does not have spark that is problem. When u hit gas pedal u get one spark and that is it ,I took the positive cable off starter generator and still get that one spark weather or not enine is turning over. I have a spark tester on it so I can see plain as day I have replaced pulsar the coil and the ignitor along with voltage regulator still nothing.I have not put a compression tester on it I know it has compression I have 25 years automotive repair experience and can usually work my way through a problem but this thing is beating me up and ez go service manual is not much help.Do u know how the pulsar works does it just ground the coil when it is supposed to fire?
Technician: Curtis B., Technician replied 6 months ago

pulsar just sends signal to igniter, it does not ground out. Look at the wiring from the Solenoid, to the igniter, is it getting voltage in key on position? See link below.

Ignition is operating as it should .Is there a way to check signal coming from pulsar ?
Technician: Curtis B., Technician replied 6 months ago

Set voltmeter on low voltage, and see if it sends low voltage signal when it passes magnet.

Testing the pulsar wire I have ,079 when magnet passes
Customer reply replied 6 months ago
That is on lowest DC setting
Technician: Curtis B., Technician replied 6 months ago

So pulsar is working. I would be checking power to the igniter fro battery, run a jumper direct from battery to the igniter power wire.

What happens if you unplug wire to voltage regulator?

Ask Your Own Small Engine Question
Customer reply replied 6 months ago
We did that and it started sparking so I replaced it now I have no spark weather plugged in or unplugged.
Technician: Curtis B., Technician replied 6 months ago

So it seemed to work , when you unplugged the old one!

Ask Your Own Small Engine Question
Technician: Curtis B., Technician replied 6 months ago

Have you gone back and tried the old igniter?

Ask Your Own Small Engine Question
Customer reply replied 6 months ago
on old regulator it did spark when unplugged.Have mot gone back to old regulator or ignitor.
Technician: Curtis B., Technician replied 6 months ago

New igniter might be damaged, due to new regulator.

Ask Your Own Small Engine Question
Technician: Curtis B., Technician replied 6 months ago

I just had a thought, when you installed new voltage regulator, did you polarize the generator/regulator?

Ask Your Own Small Engine Question
Customer reply replied 6 months ago
No I did not I am doing some research on that now.
Technician: Curtis B., Technician replied 6 months ago

OK>

Customer reply replied 5 months ago
Sorry I was on vacation checked into polarization don't need to do it got my info from ezgo directly
Technician: Curtis B., Technician replied 5 months ago

OK< but from 50 years of experience, anytime voltage regulator or generator is replaced, the system needs to be polarized.
