Just purchased a used sound loco which was advertised as a Broadcom Limited but the paperwork that came with it is all Athern. Been trying to read CV8 in both Railmaster and on the Elite to work out what it is and can't get a reliable read The last 5 reads have shown 24,74, XXX, 78, 255 Have cleaned the programming track and can read other locos fine. There is no brand name on it except made in China. Any idea why reading CV8 would give such strange answers.
