19' YZF450 ELECTRIC START ISSUE

MX Warrior Dad
We have replaced the main harness, the capacitor, the battery and the start button

Runs great as long as it is connected to 12v

Won't start if not

Anyone else have this issue?

Load test the battery. A new battery does not always mean it is a good battery for your bike.

Thank you for the reply. Are you the same paw paw from the old motosouth?

here's where we are at
Battery has been load tested, capacitor is new and has been tested. Every thing in the path to the ecu is new and good

Here is the weird thing.
If you bypass the capacitor and press the start button the bike fires up like it should and runs perfect

The only thing left to replace is the ecu and that has been ordered

Thanks again for replying
