KX500 Panthera Electric starter issues and solutions

Post by Sandblaster » Tue May 10, 2022 3:58 pm

You dropped the big coin on your KX500 E-button but it won't start.
You have pulled the plug and checked and you got a few sparks or perhaps none at all.
You have checked everything.... Now what?
The number 1 issue I have helped trouble shoot is a bad ground.
I can't tell you enough times, ground ground ground :o
So, you have checked the ground and you are 100% sure that ground is not a issue... Now what.

The simple test is to remove the spark plug and spin the engine over, holding the plug to ground.
You did that right?
Still no spark?
Nope... even if the system is working correctly you may still not have spark :o :shock: :?
Why?
Take a look at my test rig..

I have tested a lot of different ignition systems with this set up.
But when I tried this set up I had no spark regardless of the power D ignition system that I used.
Yes, I used a ignition system that I knew worked and had good ohm specs.
Why won't it spark????
A few years back I had a discussion with Adam Millar from MRE.
Some of you may know that Adam is a big CR500 guy.
Anyhow, he had heard that there wasn't enough RPM's running a no compression set up such as when you pull your spark plug out and test the system.
As it turns out this info is correct.
I turned this system over with the e-start... No spark.
Then I turned it over without the starter.
I removed the starter and used my impact gun to spin it just a little faster and it sparked very good.
So, you need compression to spin your engine fast enough to get it to spark.
You have your plug out to test it right?
Put another spark plug into the spark plug hole.
Be sure your test spark plug is grounded correctly then hit the e-start button again.
You should not see and nice consistent spark.
If you are still getting nothing... Check your ohm specs.
Yes, you will need a ohm meter.
You can get one for less than 30 dollars at your local hardware or home improvement store.
Here are the specs.

Black to black is not a issue unless your having difficulties with the charging system... but check it anyway and record your numbers...
Do not expect to match these numbers 100%.
The impedance or internal resistance of each ohm meter can be a little different.
+/- 10% can be expected, so here is a test range
Black to black .31 - .38
Red to brown 450 - 550
White to brown 63 - 77

For White to brown spec there is a note at the bottom.
"If you get a ca 35ohms, than read here" (Translations are wonkey :lol: )
That link goes to another page that says one of your coils is bad...
