Simple Wiring Question/Long Winded
in 2 Stroke Technical Questions
9 years ago
Hi all, newbie to the forums. I have a Rotax 503 mounted on my under construction Kolb Firestar II. I have the P leads wired and a self built bus system. I know the gray wire goes to the tach, but I have a black/yellow and a black wire that apparently come off the generator system. I can't get a straight answer as to what wire should go to the regulator to power instruments, lights, accessories etc. I am running a battery system (no electric starter), Facet fuel pump, and a connection for a nav/comm. It is a low hour engine in beautiful condition, and am getting ready for the first trial start. I guess what I'm asking is which wire powers accessories/fuel pump, and charges the battery. I know this is a long post, but when I talk to the seller (a very reputable dealer in the old 503's) I can't get a word in edge wise. Everything is straight forward with the dual EGT/CHT's and Hobbs. Which lead does generator power come from. Black or Black/Yellow? There are no other wires without a destination. Obviously I am really new to working on this engine. Research has been difficult at best. Please Help!!
