RX4 Charging Issue

mvander · 09-26-2023, 10:57 AM

Finally got around to digging into this further, I've had a new stator/magneto/rectifier sitting here for awhile and just put them on last night. Charging normal at around 14v idle like it is supposed to. See image for the culprit. The wire was disintegrated to the point that just brushing it with my finger broke it in half... any ideas on what could cause this at only 5,000 miles? Routine oil changes, with oil purchased from CSC. The engine got a little toasty there for a few trips when the thermostat broke. Seems like that wiring should be able to hold up to much more.

That looks brutal..... Was it hard to replace?
Glad the repair worked

Not overly difficult to get to the stator. Drain oil, remove a panel on the left side of the bike, disconnect the wires, disconnect the clutch cable. Then a handful of bolts holding the case on. 4 small bolts holding the stator onto the case.

The magneto on the other hand I did struggle with. You need a 28mm flywheel puller to get it off, and either an impact wrench or some way to lock the flywheel in place. I tried a bunch of wrong ways getting it off with no luck before breaking down and buying the tool...
