Wont Start

Postby Lucky713 » Thu Sep 13, 2012 7:34 pm



Ok, I'm about ready to sell my wing to the lowest bidder. I replaced the starter this spring. Also had a prob with temp. replaced the thermostat beginning of the season. Temp started spiking again recently to 6 bars, always runs at 3. So I just finished putting a new thermostat in it. While running the bike and filling the Radiator, the dam thing just conked out on me. I restarted it because I wanted to get the engine up to temp to make sure there were no air bubbles in the system. After starting it a second time, I went inside to get something, and when I got back out it had conked out again. I got it started a third time, but it only stayed running for a few seconds. Now it wont start. Starter cranks over great, but its acting like it isnt getting any fuel. Forgot to mention that I changed the spark plugs, fuel filter at the end of July because the bike was running rough. I also cleaned the fuel injector valves. After doing that the bike ran great. So now I'm at a loss as to what the hell is causeing it not to kick over. Any suggestions?

Did it conk out like someone just switched it off, or did it sputter and die over time, like it was running out of gas? The former indicates electrical/spark problem, the latter points toward fuel/air delivery problem.

Wingman

It stopped like someone had hit the kill switch. I have had problems with the regulator recitfier in the past, which you were so graciously able to help me out with. The bike actually has been running right at 14.2 volts since I put int he new regulator rectifier 2 years ago. I did notice a couple of my butt to butt connectors are looking scortched. not bad, but they have some bubbles in the side of the connectors like they got to hot. I was thinking of getting some heavier connectors tomorrow and replacing the 2 that are bubbled.

Butt connectors are not good enough for the current handled by the stator/regulator. Those wires really need to be soldered and heat-shrinked.

Someone with a 1200 will have to answer: Does the 1200 crank if you have the kill switch off? That will let us know if it is a problem with the kill switch or associated circuitry.

Try pulling one of the spark plugs, ground it to the engine, and crank the starter, to see if you have spark.

My 1200 LTD cranks with the kill switch in the 'Off' position. Makes me feel stupid every time I try to start her when it's set to 'off'.

I don't own one but I've helped to get a few fuel injected Aspys going.
As the Admin suggested,you need to divide and conquer.
Did it die and now won't start due to lack of spark or lack of fuel.
Each one can be quick tested with little difficulty.
Let us know if it's got spark or not,then we can guide you through the next test procedure.

I so like this site. I will check the spark and get back with you.

Ok. I fixed the 2 wires on the regulator/rectifier that had the connectors that were scortched. Thanks for the advice about soldering & the shrink wrap wing Admin. After fixing the wires I tried to fire up the bike, and no go. I took out one of the spark plugs and held it against the metal on the engine. No Spark. So anyone have any suggestions on where I go next. Obviously it is an electrical problem. I have checked the ignition fuse, and it is fine. I don't understand why it all of sudden started doing this, when it was running fine before I replaced the thermostat. By the way Wing Admin, the bike will crank over when you have the kill switch engaged. I have done it before and wondered why the hell the bike was not starting, and then realized the kill switch was on. It is not on this time, believe me that was the first thing I checked.

Unless I'm mistaken, the SEI has a pulse coil near the timing belts.If true and you have been working in that area with the thermostat,you may have a problem in that wiring, eg. a plug separated.

the pulse gen on my LTD is located right in front of the right foot,
it's the little box on the back of the right valve cover, might be a place to start..
