Actually, when I first tried the new motors, I was able to use them for a
while.  It wasn't until I went to download a different program that it
started happening.  That's what's confusing me.  Is it possible that the
L293D is burned or something like that?  I've measured the battery and it
always is >8.2V.

I found out that the charge light wasn't coming on because I was using a
different AC adapter that had a lower voltage than the battery.

Regarding the charge light on the serial board, are you sure that the
charge rate switch is in Normal mode? Th e charge LED never lights in
Zap mode.

Hi.  My board was working fine until I hooked up some different motors to
it today.  It seems that whenever I try to drive the motors the low
battery light lights up and the board gets reset.  I checked the battery
and it reads 8.4V before and while the motors are running.  Also, when I
plug the board into the serial board, the charge light on the serial
board doesn't light up anymore.  Any ideas?  Maybe a solder came loose
somewhere.  TIA.

(...) Well that would do it---it would discharge your battery. You actually should be getting more like 9.6 to 10v from a fully charged battery. Why don't you get an adatper that works and charge your battery until it's slightly warm and then see if (...) (29 years ago, 18-Mar-96, to lugnet.robotics.handyboard)
