Hi! all. ........and for my contribution ...use multicore welding wire! On short runs the weight factor is negligible. Been there got the "T" shirt. Regards Bob Harrison Europa G-PTAG 914 Rotax c/w Up graded Starter and never a problem even with 9 year old Oddessey Batteries. -----Original Message----- From: owner-rotaxengines-list-server@matronics.com [mailto:owner-rotaxengines-list-server@matronics.com] On Behalf Of Roger Lee Sent: 02 October 2010 04:44 Subject: RotaxEngines-List: Re: AMPS? up to 70 amps. If you pull more look for a problem. Use 4ga. wire even a 2ga. for a long run. The shorter the battery to starter wire the better. Make sure the ground wire is a larger size too. -------- Roger Lee Tucson, Az.
