Is the Bonnie T100 finally fixed? Was it the ignition position sensor?

So the repair on the Bonneville T100 continues. In my previous video I replaced the ignition coil, spark plugs, and HT leads, but unfortunately that did not resolve my problem.
So I now believe the root cause to be the ignition pickup sensor (apollogies when you watch as I repeatedly call it a switch, it is in fact a sensor), also known as the crankshaft position sensor.
Well there is only one way to find out, so I am going to open up the alternator casing and pull the old switch out. Since I believe it is knackered anyway, I am going to do a some rudimentary testing and diagnosis, involving a gas camping stove.
Did you know that the ignition sensor was a common problem on the earlier T100's, the Bonneville, Scrambler, Thruxton and America (predominantly the 06 and 07 years)? Well I didn't, but I do now.
Watch as I find out why it was failing, and how easy it is to replace.... and fingers crossed you can then join me back on the road.

I suspect this might be the issue with my 09 Bonnie. It gets really hot here(40+C) and when I read the OBD freeze data it shut off completely at super high temps and wouldn't start until it got much cooler. Now that it's cooler I can get it to start sometimes and when I'm riding hard it runs but when I'm in neutral or at a stop it wants to die unless I give it a bit of throttle. Might also need a TB sync. Your channel has been a wealth of information. TY sir.

@The_Scottish_Biker 4 ай бұрын

Do you get any fault codes when reading with the OBD? If its temp related it could well be the ignition position sensor, or the coil. Best thing would be to check if it is still sparking when you are getting a no start situation. Thanks for the positive feedback on the channel. More to come soon. Good luck with the fix.

@@The_Scottish_Biker throws no code but after the rain and things cooled off it just turns back on and runs fine. sounds like TB's out of sync. so it definitely sparks. going to check this out next. thank you.

@robgerety 8 ай бұрын

Job well done. Glad you have it sorted. My only comment is that when searching down an electrical problem sometimes it is best to work backward from the plug to the failure while it is in failure mode, (ie., hot). That way you are sure to land on the exact failure point and avoid time, and frustration, and money, replacing parts that are not faulty and not he cause of the failure.

@The_Scottish_Biker 8 ай бұрын

Thanks and yep I have to agree. I had no spark at the plug, so working back takes you from the plug, through the lead to the coil. Nothing out of the coil led me to believe it was faulty. I could have gone further down the line at that point, but without knowing the coil was good, any further results would have been in doubt. With a new and known to be good coil it was then clear that it was whatever triggers it, either the ignition box, or the ignition switch. Thankfully it was the latter and cheaper of the two. Easy to prove the fault and had I known it was a common fault on the 06/07 model, I would have probably tested it a lot earlier. 😂

I have a similar problem with my 1983 Honda NV400 and suspect the same problem, I like the idea of heating up the sensor and may try that. I am having problems getting any data on my bike but have seen other Honda bikes with 015-022", your 0.8mm is much bigger gap than, so may be tempted to set mine at 22 thou. The whole bike is like this with no data available at all and the bike only made for 3 years and only sold domestically. Thanks mate.

Im not familiar with your bike but it sounds interesting. As much as problems like this are a pain, you either love it or hate it. Personally I enjoy the diagnosis and carrying out self repair. Though doing it with no data can be a nightmare. Good luck with it, and Happy New Year

@allanb52 7 ай бұрын

@@The_Scottish_Biker You too mate, I have had the bike around 10 years and lived with this for 6 years, it just cutting out at the lights and needing a minute before it would start. We glossed over the pickup because it was only when very hot, but now it only runs on one pot when warmed up it is a little more obvious. If this fixes it I will be happy, but have since bought a Royal Enfield Meteor 350 which is a great bike. The Honda is much faster, but I am getting on in years. Once again happy new year and my regards to bonny Scotland.

Thoroughly enjoying these videos, I have liked and subscribed. I was looking forward to you heating up the new sensor to test resistance to confirm difference between old and new, I guess you did not want to risk damaging it 🤔. Nevertheless great job and great result with satisfaction of a job well done and peace of mind. Love the bike and looking forward to future content 😊

@The_Scottish_Biker 11 ай бұрын

Hi Mark, that was exactly it. I was tempted to heat the new sensor and the likelyhood it would have been fine in the oil bath, but I didnt want to risk it in case I ended up weakening or damaging it. The casing gets very hot obviously and I may pull the connector and measure the resistance after a run one day, just for my own knowledge. I am with you re the dealers. I tend to do most things myself, mechanical, electrical, construction etc. Then you know exactly what materials were used and how the job was completed. I know a couple of young guys that work at a dealers and I would not let them near my bike. Ive been on the spanners longer than they have been alive 😂

@RaiderWolf-yd6nm 8 ай бұрын

In response to your emergency broadcast, it appears you would have had to change the ignition coil anyway since Triumph was getting "ignition coil" warranty claims. You went a long time without having a problem if yours is an '06 or '07 Bonneville. But great video with alot of detailed explanations.

@The_Scottish_Biker 8 ай бұрын

Yeah you could be right. I only had a the bike a week when the problem manifested. To be honest doing the plugs, leads and coil was always on the cards. The bike is a 2006 and has been well serviced, but given the age I was always going to replace those components when doing the first service myself, oil change etc. i had hoped it would happen on my terms of course. The ignition pickup was not on my radar but i since know that it was a common failure on that model/age.

@The_Scottish_Biker 6 ай бұрын

It should be checked warm. Manufacturers will have different instructions for different bikes, but for the T100 I think it was (I cant remember word for word off the top of my head) run at idle for 5 mins, them stop for 3 mins, check oil level with bike stood up straight.

@The_Scottish_Biker 10 ай бұрын

Various models as part of the Bonneville series (depending on year of course). Engine sizes have changed as time gone on. T100, T120 (i believe the R was an export for the USA), T140, and of course there is now the modern classics like the bobber that fall under the Bonneville title. The various different bikes may be worthy of an idea for a video. Thanks for that.

had an issue when my bike gets wet (04 T100 790), struggling, dropping down to one cylinder then cutting out, Might just have been loose fitting crimps where the HT leads plug into the coil. I've squeezed them so the fit tightly again. Hopefully that fixed it. might get a new coil, make new leads and change the trigger coil if it doesn't fix it. Just bought a spare used Ignitor for £50 I'll keep it under the seat as a spare.

@The_Scottish_Biker 10 ай бұрын

If it is strictly related to it getting wet, it could be the water getting in somewhere and causing a short and loss of spark. Id be looking at the HT leads and the coil for cracks or any sign of deterioration. Both are an easy change. Hopefully it is as simple as the connectors you have now tightened. Happy riding.

Very interesting watch it's really is a lovely bike but this is what concerns me about these modern bike with electronics and sensors all around when these things fail that's it or it seems to me that way I was thinking on a later bike to go with my current one but I am stating to think maybe not just maybe i'm better of sticking to the old fashioned bikes like I already have 😉I am after all a technophobe and to make it worse old as well 😂and to my shame I have no idea how to use a multimeter I wonder what that would have cost if you took it to a dealership . Nice one 👌👍

@The_Scottish_Biker 9 ай бұрын

I do know what you mean but this is as simple a bike that you can get these days. I suppose this fault would be the equivalent of a points failing on an old fashioned bike. A true modern one with a million sensors and an ecu that you need a reader to plug into is a whole different game. That said, I do have a code reader for the bobber and it is very handy to see real time information and fault codes. There is a lot more to go wrong though. If its electrical or mechanical it has potential to fail. Id say just ride what you like, enjoy the good times, and hope you never breakdown 😂

@@midlife-crysis All learning has to start somewhere. KZfaq and the internet is a great resource for it these days, though I still find myself going back to the old school Haynes manual. Whilst motorbikes are relatively new to me, as I have only been riding for a year (no bikers in my family… and they arent best pleased that I have become one), I am fortunate enough to be an industrial mechanical and electrical engineer by profession. So I am happy enough to jump in at the deep end with my tools, though I can appreciate not everybody is that way inclined. Hopefully my videos can show that its not always difficult and with some basic tools, the job can be done. Ive only owned the bike for a couple of months. Its a 2006 T100.
