Good to know. > The simplest way to get a short motor starting delay is to add a small relay ... > Make sense? Yes. Thanks! That's a much smaller capacitor than trying to debounce across both the contactor coils, which was what I was vaguely thinking of last night. I ordered 8 of the 4 relays I needed for my zener-based battery DoD indicators: http://www.excesssolutions.com/cgi-bin/category.cgi?item=ES3735 on the theory that I'd find other uses for them... Since it's a 48V relay I should be able to skip the series resister to the relay coil. > The SB350 is rated for 350 amps continuously. The fuse is only good for > seconds at its rated current.

The "350" is the hot connect/disconnect rating, which I didn't find out until last night when I found the specs on the anderson site. The SB175 is rated 280A continuous. If I damage the contacts pulling it apart because it is pulling more than 175A I'll be happy that I pulled it apart. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
