Gs450l abrupt loss of power?

The caps on there now simply thread into the center of the wire. Ill trim some wire and swap caps, see if that changes any values.
Thanks!

Yep that's the deal, and good idea to swap.

OK what causes the coil to fire? The negative terminal being grounded by the ignitor?

The (-) leads coming into the coil, where do those go?

Reason Im concerned about it still is that the left one is grounded and completes a circuit, the right one does not.... This is with the bike on or off...

Thanks!!!!

For a spark to fire, firstly the ignition coil is charged (turned on) by grounding the negative terminal of the primary part of the coil. This is the bit attached to the wiring harness.

Then, when the negative terminal is disconnected from ground (turned off), it discharges via the secondary coil via the HT lead and spark plug, causing a spark.

So reading your post again...

Where exactly are you measuring to determine the left coil is grounded?

[83Rabbit]

Positive lead to coil to negative lead to coil, measuring between the two the left side reads voltage, meaning the + / - are a complete grounded circuit, the right side reads no voltage when doing + / - coil leads, but when moving the ground test probe to an actual known good ground, a circuit is completed and it reads 11.5 v.

So im questioning why the negative lead/terminal on the left coil is grounded but the right is not...
This is with the key in the on position.

Aaaah I think I get you.

If I'm remembering correctly, with the ignition on one coil or the other will be "on" (grounded).

To prove this, rotate the crankshaft 180 degrees and this behaviour should move to the other coil...
