ARrrggg ( Charging )

[MrMe]

Got a r/r from a cx 500.

I ran the ground wire directly to the bat -
and this wire is still getting smoking hot ?
Why ?
Is this a ground short ?
bout to give up.

Did you run the ground straight from the RR to the Battery negative, or did you run a extra wire from the harness (with the RR hard-wired into the harness) to the battery negative?

[MrMe]

r/r - directly to bat -

as far as i know the ground aint sposed to cary any current.

im lost...

If you are sure the wire you are talking about is the minus, and there is no other wire coming from the R/R also beeing very hot, then you probably have a shorted stator or broken R/R rectifier.
Check all 3 white wires coming from the stator with a DVM set to resistor measurement, with R/R not connected. None of them should be connected to ground/chassis.

If one or more of the 3 wires is connected to ground, it wil short the current from the stator to the chassis and only trough the black wire back to the R/R and stator. The current can be very high so it will heat up your wire (and possibly more).

There is a very good charging system test (PDF file) at the electrex site: www.electrexusa.com.

This will help you to check out a charging problem and to see what part/component is faulty.

Normally the ground wire carries the same current as the Red wire (positive). The current flow is a closed loop, what goes in, must come out.

yea i know
im gonna go test the stator. I thought it tested fine but thats the only reason i can think of for it heating up that wire.
Oh well at least the charging system will be new....

[MrMe]

stator passed every test except ac voltage
all 3 were over 50 but not the same.
So i assume the stator is pooched causing the short ?

[MrMe]

hmmm me thinks i found the prob.
is black crumbeling epoxy on a stator a bad thing ?
oh well.

You got it!!

Welcome to the Flaming Stator Club....

Super, you could ask MrMe to send you his fried stator for your collection!  ;D

Yeah, I am still working on that neclace for you-know-who!!! LOL!!

[MrMe]

Now the question is are the stators from eletrex better than the oem ones. I have no issues dropping that amount of coin
other than 3 weeks without riding. But i have issues with putting an oem one back in there. I dont want to do this every season.

I bought one from Ricks Electrics, and it works great.  Very happy with it.

Hmmm - black, crumbly epoxy - I had one just like that.  Welcome to the fried stator wing of ROV!   ::)

Mine's also a Rick's.  Only been in about a year so I can't speak to durability.  Maybe not as pretty an Electrex but so far, it works great.
