More Electrical Woes

[Road Rage]

First off thanks to all who have posted before me, your threads have given me a good start however I'm still stumped so here's a synopsis of my problem and process so far.

E start stopped working last ride, had to kick start it for the day, sounded like a dying battery as the starter motor turned slower and slower.

Charged my battery when I arrived home, charged to 12.9 V

Voltage at battery with engine running 14.47V

Removed, disassembled and cleaned starter motor, brushes in spec.

Reassembled starter motor (marks all lined up) and reinstalled on bike.

Removed starter clutch assembly and the starter motor spins freely when I push e start  so I put it all back together.

Still sounds like a dying battery when I try to e start.

Tried boosting with our car battery, still turns over extremely slow and won't start. Kick started 2nd kick

charging voltage while running now is 13.4V but I assume that's due to the battery being drained.

So for those who have more experience with these type of things, where do I turn next?? Going to have my battery load tested tomorrow at a shop.

 

Cheers

Colin

What year is the biike? How old is the battery?

 

Perfect opportunity to upgrade to an Earth X???

Sorry about that, its a 2007 WR450 with a new battery I installed 3 months ago (stock OEM replacement)

Sound like the field winding in the starter going bad.

Ok so for me here are the final findings, auto decompressor was malfunctioning due to being gummed up and sticking, overloaded the starter and caused the windings to burn out and destroyed my battery. All fixed and back to good working order!

Sweet.

Don't ever buy another stock battery. It is a POS. Shorai or EarthX or other similar type.
