12v is the most fire prone voltage, add the fact it is DC.
Grounds need to be clean, tight and well secured from becoming lose.
So start from there, check the wiring run from the starter to both the + terminals, ensure no chaffing of the wire and that all connections are clean and torqued.
Do the same for the grounds, then start looking at other places. A little resistance makes big heat when dealing with low voltage I^2R = heat in watts
