baler iso bus connection question

[seedman stains]

My iso bus baler is connected to my non iso bus tractor with the cable onto the starter motor ( with anderson connections + on the starter - engine block)),I had some out the other day and he said direct to the battery as the starter could cause a surge and damage the box ,is he right?

Won’t so much cause a surge as a power drop. If you were to have the box on and then start the engine I have seen boxes be re set as the power can drop so low on start up. It’s rare but can happen

This explains a few questions, there should be no issues though.
If you have an isobus compatible tractor it obviously just means you can link your machine to the tractors speed sensor for instance.
