for your excellent info. I'm going to get my hands on my manuals
soon. One quick question though. What is the power pulse switch?

Subject: Re: (ET) Charger heating while driving
I had this exact problem on my E12 and received a lot of help from some
very nice people on this list and finally solved it. So I'll share
what happened with you.
The resistors take current and heat in the first and second speeds of
the controller and should stop heating in the third speed. In order to
achieve the third speed, the circuit between the solenoid contactors
and the centrifugal switch needs to be closed. You can manually close
this connection by pressing the power pulse switch. If you hold this
switch down after achieving second speed and you go into third speed
then the problem is in this circuit. It is either a worn switch in the
speed control, a defective 2A solenoid connector, a defective
centrifugal switch in the motor, or a bad connection. After testing
all of the above, it turned out in my case to be a bad connection at
the Molenex connector in wire # 36. This wire runs from the motor's
centrifugal switch to connector 2A. I just patched around it and it has
worked just fine since. Make sure you use the correct schematic for
your machine and test until you find where the break is occurring.
If I can be of any help, let me know.

I notice a electic heat type smell. Then feeling the hood I
can feel the heat that the power resistors in the charger area give off.
I've checked to see that the charger is really off by rotating
knob while plugged in.
I've been trying to find the manuals, but I'm having
trouble finding where I "filed" them..
Can I take the charger out?
I plan to charge with PV panels soon...
