Ok, then Starter it is...
But make sure the larger gauge wires are to the heftier Fused terminals.
I have seen "swapping" of wrong AWG wire to wrong terminals, and it will blow that terminal fuse and these things are INTERGRATED - so you blow one, you have some spares but the whole terminal will need to be replaced soon.
So you know that Yellow with RED stripe wire is not meant for 250A or even 200A. IT belongs to a smaller terminal - usually 60A - the EPAS (Electric - Power - Assist - Steering) - and is about #10 AWG - about MAX for that size wire.
Here's some help from my system - color code is a bit different but the "RED" wire is from Starter and just above it - is a 450 Amp BLOCK fuse to keep the battery from starting a fire from it's CCA rating.
However - if you attach a wire of smaller Gauge - and put more current thru it - the fuse link won't blow, the WIRE will - ruining your day.
Many of those wires - above, look close - the lugs to wire are SOLDERED by myself to extend the life and service they can provide.
Highly recommend that this soldering step be done to any vehicles system to improve the reliability of their vehicles electrical system - Ground Lugs and every terminal they have access to - do it, if it's isn't already done..
