Re: (ET) FW: charger problem
However, new data wants me wants to retract my statement somewhat.
Were the diodes checked again after replacing the capacitor. I assume yes, since that is when you started your new troubleshooting phase.
It sounds like you very deeply discharged the batteries on your first outing of the season. Then the charger cap blew trying to recharge them. (as a note, power guage should never go red when mowing)
Where'd you get the capacitor from? What are it's specs?
Can you check voltages? It may be that the batteries are just lower than you've ever seen and the charger is running harder than you've ever seen. Or it could be that something is definately wrong. Which I would lean towards being the case; the charger should have been able to bring the batteries up from dead without killing itself.
Please measure the voltage of the batteries, both on and off charge.

Along with Tim & RJ, what is the output voltage??

Well, I've had two cups so far and I'll have to agree with RJ;
The harder the charger works, the louder it hums.

I'm confused.{ But then it IS Monday morning, and I've had but one cup of coffee.} What flavor of ET are we working on? The first charger diagram I pulled up (since I'm just guessing. <G>) shows an S1 and an S3 but no S2.
Wire 30 goes to CB-2.It HAS to be there, or the charger's output is not directed to the battery pack. The loud humming noise you hear when it's connected could well be the sound of the charger doing exactly what it's supposed to be doing. Charging. :)
What conditions existed previously to start this investigation?
Fetching that much needed second cup of Joe........

Hi,
My charger hums quietly when plugged in and the #30 wire from the circuit breaker is not attached to S2 on the charger, but when attached to S2, makes a very loud humming noise. The capacitor is brand new and I a local alternator shop that rebuilt all my tractor motors told me that the diodes are fine (they recently replaced them). The resistance from each diode to the heat plate measures zero. Any ideas? Do I need a new heat plate? If so, where do I get one?
Thanks!
Paul
