My friend's 06 Night Train all the sudden started only firing on&nbsp\\;one cylinder and the check engine light came on last week, this happened after ridding about a hundred miles and then it started running OK for a while then it did it again a couple of more times during the last 50 miles.&nbsp\\;&nbsp\\;

Since we had just gotten gas, we drained the gas and changed the plugs and checked everything over.&nbsp\\; All seemed OK and today it did it again.&nbsp\\;We checked the codes and had the 3 codes below in order.
P00265 - Battery voltage low
P1355 - Rear ignition coil high/shorted
P1352 - Front ignition coil high/shorted

We checked all the connections, plug wires&nbsp\\;and looked at the coil and saw nothing.&nbsp\\;The battery light did come on one time for a couple of seconds, but the bike starts fine and lights are bright even if it is not running.&nbsp\\; We then cleared the codes and took it on a test ride again tonight.&nbsp\\;Again 3 times in&nbsp\\;a 20 mile ride it did it again.&nbsp\\;The check engine light came on and it started running on one cylinder.&nbsp\\;Seemed to happen just after harder acccelleration and only lasts a few seconds.&nbsp\\;The light goes off and it runs OK again.
We checked the codes and had the 3 codes below in order.
P1355 - Rear ignition coil high/shorted
P1352 - Front ignition coil high/shorted
P00265 - Battery voltage low


Anyone have any idea on what this could be?.&nbsp\\;\\\\\\; His warranty just ran out about a month ago.
