I recently installed a one wire 100A alternator for my 67Chevelle, at the same time I replaced the battery cables and removed an electric fuel pump at the rear of the car and installed a stock pump. Somewhere in the switch I missed something...with a fully charged battery I don't even have a dome light come on let alone start. Anyone have an idea where I went wrong?

Thanks

gonna have to go back and check stuff out

Did you remember to re-connect the wire that goes from the battery positive to the horn relay/buss bar? That would be the first place I'd look (been there, done that).
