The illusive Boxford 260vmc

[irving2008]

Thanks Irving, its working now, had to connect the rtn to chassis ground...

That suggests a ground fault... is your BOB optoisolated?

Next job is put together the TACHO!!! this is just a temporary one as im going to give cash to this person who is designing "The Ultimate Rev Counter"!!:naughty:

Lets just see if we can get the project off the ground first.... so many toys to play with, so little time to do so....
