Hi,
I find it a bit difficult to understand which cable thickness and fuse I would need to use for the Cyrix CT 120A.
For the main connections (30/ 87) I plan to use a 25mm² wire and 120A fuse as is described in the product's datasheet. The cable length would be about 6M.
What I don't understand is which thickness and fuse to use for the start assist (85) and connection to the battery (86). The datasheet says the fuse can be 0,1A, which would indicate a rather thin wire can be used. But I don't understand how that's possible: my starter engine would draw a lot more than such a small fuse and wire could handle.
Second question: do I really need to connect the negative of my "appliance battery" to the negative of the "start battery"? Can't I just ground them both?
Kind regards,
Marc
