Customer Question

Have a 2005 Softtail Deluxe. Have had this problem since the beginning. On a long trip the engine will shut off, the only way to restart it, is to turn the on-off switch off and then back on. Some times it will take two or three times before it restarts. Most of the time it happens at a hight rate speed.(70-80 mph)

there is only one circuit on your bike that can fail which requires the ignition turned off (for more than 10 seconds) ten back on to reset.

that is the Bank Angle Sensor BAS) which is a circuit inside your turn signal module (TSM) which is designed to disable the ignition when you fall over. it is also known to fail and disable the ignition whenever it feels like.

to determine if this is your issue, you can remove the light green wire with the gray stripe (LGN?GY) from the TSM connector and ground it.

a hard ground on that wire will provide an ignition enable command and restore stark.

if your problem goes away, you will know the BAS was the cause and you can replace the TSM to restore the function or you may decide to ;eave it grounded out, knowing if the bike falls over, there is nothing to kill the ignition except the kill switch and the ignition switch.
