You don't what to know the shipping price. Anyway I ordered some colored battery wire thinking it was 4awg and find out its 6 awg. How critical is the difference given that the piper sport is wired 6awg and my aircraft is a simple vfr Dynon with a Jab 3300. All bobs drawings have 4 AWG but my limited understanding thinks 6 would do the job. What do you all think.? Battery , master sol , start sol to starter?

If the engine cranks OK, 6 AWG is good enough. If not, try some larger welding cable, especially for longer distances. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459490#459490 ________________________________ Message 3 _____________________________________ Time: 05:20:30 AM PST US From: "Robert L.

Battery , master sol , start sol to starter? >Chris If you measured all the 6AWG wires and added them up, what's the total? 6AWG is 0.4 milliohms/foot or 40mv/ft voltage drop at 100A. So something like 5' of loop-length in a 6AWG cranking circuit would drop 0.200 volts. Not a serious loss. Longer paths, cold temps, higher currents would have different conditions but not by much. You're probably fine. BTW, welding cable is fine wire for cranking circuits and you can probably get that stuff locallly.

When I looked at length it was no longer than 3 feet battery to starter motor. All your drawings had 4AWG not sure why that was and so I just had to ask. Chris.
