I couldn't get my vernier caliper into the hole. I wasn't able to find a good match in my extensive collection of spares for either the B1 or the B2. The closest matches were prone to arcing if the cable moved. So I cut the green cable. This is for attaching the laptops to a automobile DC supply. http://dev.laptop.org/~quozl/2007-02-06/s08-348x.jpg 1. disconnect power adaptor from AC supply and allow to discharge, 2. prove discharge using a voltmeter and 100 ohm resistor, connected in parallel across the output plug, 3. determine an appropriate location for the task (my cut was 100mm from the adaptor), 4. observe or mark the polarity on the cable (the B1 power adaptors had a white ink mark on one of the conductor sheaths), 5. place heatshrink over ends, strip ends, terminate, shrink, 6. apply power, measure output, connect to laptop. In the photograph, the adaptor is to the right, the output plug is to the left. The wires to the adaptor were anchored directly to the screw terminal block. The wires to the output plug were crimped with 2mm spade connectors, since they would be regularly removed from the terminal block and attached to another terminal block. The heatshrink tubing acts as strain relief. -- James Cameron mailto:[EMAIL PROTECTED] http://quozl.netrek.org/ _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
