Question about 2004 Aprilia Caponord Rally Raid
Think I may have a problem with a coil. The story so far; Riding along and EFI light started flashing. Flashed for a few mins. then stopped. Took the bike homw and plugged it in to Tuneboy
Which gave me the following faul codes P0353 Ign coil 3 malfunction and P1357 Ign coil 3 Short circuit to vbatt/over temp I then started up the bike and the EFI light was flashing again. On checking the sensors page of Tuneboy it showed coils 12 & 4 with a dwell reading of 2.1-- whilst idleing but coil three would sit around 2.1 but would then drop right down to 0.4 for a few seconds before coming back up to 2.1ish. So the questions are, what does short circuit to vbatt/over temp mean? I assume that the fault codes and EFI light flashing are connected with the fluctuation of the dwell reading on coil three? Does this mean that coil three is on its way out and that I should order a new one? I should add that the bike is running fine. My main concern is that in two weeks time I'm taking the bike to France for 2 weeks / 2000+ miles and don't want to have coil problems whilst away. On a different subject (although still electrical) can anyone tell me the colours of the tacho feed wire, I have studied the diagram from the Caporider site and in my handbook but still can't find them,I had two coil failures. Both of them exhibited extreme dwell variance.,,,
