I parallel two motors frequently with no ill effects. There is no generation taking place. It will use more battery current for the two motors than it would for one, but it is also doing more work. -- Bob Fay rfay@we.mediaone.net The Shop (URL) (...)

It looks like I have most of the problems solved. However, one serious problem seems to be related to the length of the command line.
