Onan does not start

My Onan is totally dead nothing happened when trying to star not a slightest click. I have measured 12,8 volt between +on the starter and minus on the alternator, but only about 4 volt between + on the starter an - I believe it is on the starter see attached photo the same reading 4 v between plus on the starter and the ground strap.
I assume the reading should be 12,8 and not 4 volt?
Any idea where to start searching?
