Paul Craddock Posted July 7, 2022 Share Posted July 7, 2022 I'm just re-wiring the battery, master switch, starter motor cables and not sure what size cable to use. The engine is a tuned 2 litre Zetec and the starter motor is an Edge Hitachi type. I reckon 16mm (40sq.mm) 110amp would do the job, but just wanted to check to see if anybody actually knew the answer.Thanks Link to comment Share on other sites More sharing options...
Wrightpayne Posted July 7, 2022 Share Posted July 7, 2022 Paul,I have a suspicion its 25mm - have you got an old piece to either a) work out the area of copper using some basic maths or b) compare the diameter to what is available at Polevolt, 12vplanet et al?Ian Link to comment Share on other sites More sharing options...
John Vine Posted July 10, 2022 Share Posted July 10, 2022 My red battery/starter cable (to/from FIA switch) is just under 9mm O/D (including insulation), which I imagine is this one (16mm 110A).ETA: But assuming the insulation is 1.0 - 1.5mm in total, a little basic maths suggests something closer to 25mm?JV Link to comment Share on other sites More sharing options...
