Re: (ET) Battery Charger


The battery charger that comes with the ET works adequately. I realize 
that it
is 30 year old technology, and that advances have been made. However, I 
that new chargers do not have enough to offer when a repair to the et 
charger is
rather inexpensive and very easy.

things (or maybe both):
Bad heat Sink
Bad Capacitor

Testing these parts is not easy without specialized tools, so start by 
the HEAT SINK (which shouldn't cost more than 15 bucks).

Be sure the charger is off and that the power disconnect is off before
attempting this.

After making this repair, I found that my old ET Charger produced a higher
voltage, charged faster and gave the batteries a true FULL CHARGE, so that 
could operate it longer.

The only fault that I find in the design of the old ET Chargers (compared 
to new
chargers) is that the old chargers permit the overcharging of batteries, 
can boil off water from the cells. If you check the level in the cells 
(once a month) you can be sure to add distilled water before any damage to 
batteries occurs. A bit of experience will tell you how long to set the 
for. Using the gauge on the timer listing the age of the batteries in years
often overcharges the batteries - especially if you did not run the 
batteries to
a low charge state.

And do be sure that the timer on the charger is functioning properly.... A
broken timer can let the batteries charge indefinitely and fry them.

I always leave the seat and hood up when charging, just like the owner's 
suggests, to let any fumes dissipate with ease.
