Neither switch exist on Reaper. 2005 Night Train, I bought new in Canada.

Cheers!

 

You can unplug the BAS and it will run. Just will have the check engine light on.

 

the bas is not a stand alone unit on his bike. it is built into the tssm

 

I was hoping someone would say that -Yeah, you just unplug it and jump a couple of pins. Guess not. I would have liked to get rid of it as it seems to come up quite a bit in trouble shooting problems.

 

I just spent a while reading about the TSSM in the 2001 Electrical Diagnostic Manual.... I can follow along with this stuff, but for some reason I have to read everything twice to get it to sink into my head... Electrical is NOT my strong suit...


Anyways, as I think you know, your BAS is in the TSM/TSSM..

It will disable the coil in the event the vehicle tilts more than 45° from vertical for longer than 1 second.
To restart the motorcycle after shutdown has occurred:
1) Return the motorcycle to an upright position.
2) Cycle the ignition key off-on before restarting the vehicle.

Reading this made me think...... Just for the hell of it.... have you inspected the TSSM to ensure it is firmly mounted...?

There was a case on this forum when a guy couldn't start his bike. His coil was not getting power. He was getting ready to replace his ECM, until someone mentioned the BAS. He decided to check the TSSM connections first, and found the TSSM bracket broke. His TSSM fell over, and the BAS was triggered and wouldn't reset because it fell out of the bracket and was constantly in a position that caused it to read over 45° from vertical. He fixed the bracket, reset his BAS, and all was well.
Perhaps your's is loose and randomly tripping... A long shot I know, but it would suck to be searching for a fault with a properly functioning BAS...


Back to the Electrical Diagnostic Manual...

The trouble shooting section starts with the checking (or retrieving) of trouble codes. There is a lot of information in this book, but the TSM/TSSM section is 76 pages... There are a lot of flow charts, circuit diagrams, etc. to aid in diagnosing the various trouble codes.

If you had a code, I could take a snapshot of that section, but I will not be able to duplicate the entire section for you to read.

If you focus on wires between the TSSM to ICM, ICM to coil, and ignition to TSSM, and they are all good, then it would seem to suggest the issue is the BAS in the TSSM, or the ICM....Not being an electrical-type guy , I do not know how to isolate and measure the outputs between these without a breakout box, to see if one of those two are in fact causing the issue...?

I would suggest, other than throwing parts at it, you could try to find a copy of the 2001 Electrical Diagnostic Manual on eBay... In 2001, the Electrical Diagnostic Manual was two volumes and quite expensive. You will just need Volume II for your bike. Volume I is for 2001 XLH & Dynas. Volume II is for 2001 Softail & FLT, along with the appendix for the electrical connectors.

Sorry I couldn't find a quick easy answer in the manual. It's still possible it's in there, but my non-electrical mind could have missed it....

Good luck with the repair...

 

I appreciate the detailed reply. I will def look into it. I know i had access to the TSSM before and it didnt look like the mount was broken or anything. What gets me is there are no touble codes. So, instead of the TSSM being bad or something broken in there, im wondering if a wire somewhere is bad or broken, just for the simple fact it happens randomly. I will check the wires and the mounting when i can get it into the shop i work at. Thank you again.

 

Ok, so quick update. Was messing with the TSSM yesterday. Pulled the 10 pin wire, which is the ignition enable signal. Which feeds the built in BAS. Grounded it out, no start. No spark. So plugged it back in, started up. So we held the TSSM in the proper position it is on the bike, Started right up, when turned the TSSM the bike cut off like it should. Pulled the wiring harness off the TSSM to feed it back through the bike to put the TSSM back in place, and noticed that the 10 pin wire had pulled out a little bit. Put it back in, no start. Wiggled the wire and the bike fired. So i pushed the wire back into place, and put a rubber boot in the back end where the wire feeds into the connector, to keep it in place, put it all back together and the bike fired up, idled for a good 20 min, which before it would die in 2 to 3 min at idle, had a blower on the motor to keep it cool since it is air cooled, he took it on a ride and it never died on him. So I'm hoping that fixed the issue being a loose wire in the connector, unfortunately there is no way to tell unless he rides it more and see it happens again. but I'm pretty confident that was the issue.

Thank you all for your input, and i will update once we figure out if that fixed the issue.

 

It most certainly could be the cause of your issue... I'd be willing to bet if it happens again, you will find that "rubber boot" misplaced and the wire slightly backed out of that connector again... Then time for a new connector body...!

That's an excellent catch and the way to be persistent when looking for an issue... Kudos....

Your issue and repair highlights a couple things you see mentioned all the time on this forum...

1) Check the connectors.... It is amazing how little things with connector pins and how they contact each other can be so fragile... alignment, proper install to connector, corrosion, and/or damage (like being slightly bent). They are so durable in most cases, many will just disconnect, add some dielectric grease, and reconnect. Not really doing a proper inspection and paying close attention to the details.. Like I said, great observation on your part..

2) Do a proper diagnosis..... You could have thrown a new TSSM and/or ICM at that problem and still had the issue... That would have been very frustrating and costly.... Again, great out of the box thinking, trying to locate the actual issue...You stayed focused on the parts, wires, connectors, and modules that you believe were involved based on your observations...

Two very valuable lessons people will be able to learn from your thread....!

 

Boy, that is a double from Mr. H.

As for electrical pins. Many times the wire end has the pin or socket and there is a little tang that is supposed to go into the connector socket and the spring tension "clips" it into place on prevents the pin or socket from backing out. Sometimes those do not get indexed quite far enough, or the tang is defective. Also, another note - keep that in mind if you are removing a wire from a connector as how it works, as there is a tool that slides in from the forward side and detents that tang so the wire can be slid out. I do not recall the actual name - get out of the biz and you forget all the stuff you knew like the back of your hand...

 

so the loose wire was not the issue. we fixed that and it still died out. so he broke down and got a new tssm. it is on the way now. so will update after we install it and he rides it for a while to see if the problem is fixed.
