My 1200 Interstate Motor Shuts Down

Post by black1200 » Fri Jun 27, 2014 2:45 pm

I have a 1986 Interstate that once and a while the motor will just shut down while riding. All the electronics will stay on but the bike will not start back up unless I turn the key off and then to the on position. The motor will then restart and all is well until it happens again. This is telling me something has to reboot when the key is off and then turned back on, but what. I believe this bike has no Bank Angle Sensor or Side stand sensor. Any thoughts as to what I should look for to stop this from happening would be greatly appreciated.

This sure sounds exactly like the behavior of a faulty bank angle sensor - but the documentation I look at, shows it on only the Aspencade and LTD for your year bike. I suppose it's possible that yours has one for some reason - stranger things have happened.

I would have a look just to be sure. This is what it looks like:

Seems to me there is a rubber cradle that the angle sensor lives in... If this rubber cradle fails, then the sensor likely will cause shutdown... Digging deep into memory here, but I believe if you simply unplug the sensor it disables it from killing you engine... Does it not just act like a kill switch (i.e. ground out the coils) ???

Another thing that came to mind was the kill switch itself... Check the wires and the switch for signs of shorting... A chaffed wire could do it... The kill switch on my 87 was supper sensitive till I thoroughly cleaned it with a good plastic safe electronic parts cleaner... I took the handlebar clam shell apart and soaked the switch while moving it through on and off position... It was fine after that... Prior to that if I just touched it the bike would die...

Another though is possibly the ignition switch needs a good cleaning (ya have to take it apart to get at the cantacts)... Google it and you'll find many article on how to do it...
