Topoff Posted April 21 Report Share Posted April 21 Hi can anyone tell me the amperage rating of the brown wires (two sizes) that come from the starter motor to feed the loom ? Thanks. Laurence. Quote Link to post Share on other sites
RobH Posted April 21 Report Share Posted April 21 I guess this is for an early car with ammeter - are you looking to replace the wires? The larger wire which goes to the ammeter carries the peak battery charging current which can be 30A or more. A suitable wire for that would be 84/0.3 rated at 42A, to give some margin. The smaller wire basically just carries the horn current which peaks around 10A and the hazard flashers at 7A plus maybe a few other things if the car is a US model. A suitable wire size is 44/.30 (27.5A rating). Quote Link to post Share on other sites
