New coil
 
My ezgo txt is a 2004 model, unfortunately the coil seems to have seen its last working trip.
What I would like to know is will a pre 2004 model coil work on my model?
The price difference plus postage and import duties is enormous

Pretty sure your 2004 model will have an MCI engine. You can easily tell by the exhaust manifold if the manifold is cast into the head, it is MCI....pre MCI had a bolt on cast iron head. The MCI coil produces a hotter spark, I don't believe the older style coil will work properly in the MCI engine. What makes you think the coil has died? Look in the tech section of the forum for the manual...you can test resistance across both primary and secondary sides of the coil to verify if it is good or not. Failure to spark often is caused by other issues.

Welcome to this side of the nut house, before you replace anything remove any and all of the black ground wires over by the starter solenoid and clean them very good.
For some reason the grounds like to corrode there and cause a loss of spark

No , it will not work. The coil was part of the newer updates on these MCI engine.

Testing the Ignition Coil
Set the meter to the ohms scale, measure the resistance
between both primary wire terminals and between
the secondary wires (Ref Fig. 3 on page M-5). A normal
reading would be: Primary (+ and -): 1.87 - 2.53 W and
Secondary (A and B): 10.8 - 14.6KΩ. If readings
obtained are out of the above ranges, replace ignition coil

Re: New coil
 
spot on. can anyone supply advice on testing with a multi tester

I included a picture on how to do this. Did you not see it ? We are talking about checking the coil ?

Jpudds 10-06-2021 10:30 AM

Re: New coil
 
thanks trig 123, goes to 00.0 on primary and around 7.0 on secondary

Jpudds 10-06-2021 10:32 AM

Re: New coil
 
yes thank, just tried it and gave reading I found; what ohm setting do you test on for best results?

200 ohms 8)

Re: New coil
 
thanks trig 123, no resistance on primary nothing on secondary.
is there a way to test the ignitor?
I need to check the wiring, can anyone supply a diagram please

Not a way to test other than installing a known good one .

You can check the pulser coil though.
Unplug the connector leading into the engine. Test with meter set to 200 ohms.
433.5 - 586.5 Ω should be observed. If the measurement
obtained is out of this range or if a reading of no
continuity is displayed, replace the pulser coil. Make
certain that the air gap is correct. Set with a .032 feeler
gauge.
Check grounds good as suggested in first few posts by JPonLKN and crash12888 8)

Re: New coil
 
thanks trig 123 I will test and see, how can I test the air gap is there a procedure

The air gap is probably ok but here is how to do it :thumbup:

Sorry to take so long getting back to you, been to sunny Wales on holiday.
I'm getting 00.0 on primary and upto 157.3 on secondary, set to 200k on both my multimeters.
looking at your advice it looks very much like the coil is at fault.
A
lso I have been told that ezgo no longer supply the ignitors and that the engine is now obsolete, is this right?
Thanks for everyones help

Jpudds 10-23-2021 06:40 AM

Re: New coil
 
Thanks Trig123 checked gap on pulsar coil that is ok, on 200k I'm getting 00.4

Yes, bad as I hate to say it ezgo does not supply the ignitors anymore. They do have the coils here in the USA at ezgo dealers but they cost $375.71. There may be a few dealers that might have an OEM ignitor on the shelf but I sure don't know where one might be.
They only made these MCI engines four years so parts are indeed rare. I changed mine over to the pre mci engine because I keep parts for them. 8)

That would appear to be out of range being it should be in the
433.5 - 586.5 Ω range.
Check with another meter to make sure.
None of those are available here in the USA at dealers. At one time I had a good used one in my shop but someway it came up missing.

Hi Trig123, Thanks for your informative, as usual, reply.
I have located a Mitsibushi coil off a Suzuki Vstrom motorbike number F6T546 which is identical, apart from the connections, plug not built in.
I will try it when it arrives and inform you whether it works..
Thanks for all your help

Keep us posted on the outcome, that might be an alternative source to our dilemma over here.:thumbup:

Re: New coil
 
Hi Trig123, fitted coil, identical apart from the connectors.
Started first kick after changing the connectors, bit of choke off it went, so anyone stuck for a new coil look for this one
