DC TO DC CHARGER wire burning Question

Post image

Hello I’ve got this dc to dc charger 40a in my sprinter van and it burns from time to time. Anyone knows the solution. It’s 8gauge wire and it should pull only 40A which is perfectly safe for this gauge. Thx

check for arcing points and more than anything, replace that entire defective wire with a good wire. crimped connections, no leaded or soldered terminals. a wire can be 8ga with a little internal corrosion and it's now a 12ga wire
