Re: (ET) Charger out.

Chris,

I would assume you know that the master disconnect has to be ON to 
charge, so with that, you should make sure the circuit breaker on the 
front dash panel has not been tripped. If that is fine, then you have a 
bad diode. Sounds like the charger is turning on since it hums, so the 
timer motor is fine. You can make sure that the charger is grounded: 
ground lead from plastic connector goes to transformer frame and 
secondary center lead ties to a post on the base along with the 
negative lead coming up through the frame with the positive lead for 
the charger. I would replace the cap and both diodes at the same time. 
What did you do to "rebuild" it?

Well, interesting. The charger on my E15 seems to have stopped working.
It's been rebuilt, the symptoms are as follows:

Charge: Hum from transformer. Disconnect the capacitor, no audible hum.
Plug capacitor in, hum. Voltage at battery is 36.4, no change with
charger on or off.

Disconnect charger DC output and measure: 39.4 volts on digital meter.

Any ideas?

Chris
