Enjoy your adventure! I would have responded quicker were it not for the time difference across the Pond. Spent a bit of time in Canada myself when I was in the Royal Air Force. St John’s Goose Bay and Halifax in particular the Split Crow pub I have great memories from!

Morning @motopoeta . I would look at the earth/ground connection as the likely culprit. The positive terminals are ‘designed’ as such and any bolt you use as an Earth/ground connection unless it is a designated Earth/ground is really just a ‘compromised’ one, especially if it is being snagged. If memory serves me correctly I used a larger ring tongue terminal and bent it slightly downwards to stop the seat snagging it. There is a designated raised ground stud at the rear of the right hand cylinder head on the engine if you fancy running the cable there without having to strip anything out for access. It was the one I intended to use when I first researched fitting the pigtail.
Edit Afterthought: I am unaware of how the Thunderbox is supposed to be wired but the positive terminals under the seat are permanently powered, does the Thunderbox need to be powered from ‘an ignition sourced live’ I am wondering perhaps? Good luck with it! Either of the two theories above ‘could be’ the cause.

Best practice and husbandry. I am afflicted with minor OCD, the perceived surliness is obviously a new affliction. The screw in the bottom left of the picture is recessed and the ring tongue terminal would not fit in the recess. Possibly a longer screw and certainly a washer would also be required. The raised terminal is for jump starting/affixing a croc clip. I didn’t want to raise it any higher than it already is and I wanted the insulated cover to fit securely. Having checked initially that the screw where the negative terminal is currently fitted with an ohmmeter was a good earth/ground I could see no reasoning to investigate another position further away from the live than was necessary.

Deeply confusing photograph above because it looks like you're connected to jumper terminal negative and ground through the frame.

I do not understand how the confusion arose. Both terminals on the bar are positive as you surmised eventually! The pigtail leads are both black and are of the same gauge. One has a huge white label adhered with large red ‘+ve’ labelling and a red ring tongue terminal on it, the other which is the same gauge of cable has no labelling but a black ring tongue terminal on it. The ring tongue terminals alone being colour coded dictate where they should be fitted. Glad you got there in the end!

Really? As an Electrical Engineer for over 40 years I can guarantee you it is NOT a weak earth and has worked for several owners! If concern is that great simply run the earth/ground to the earth ground stud at the rear of the right hand cylinder head. That has exactly the same ‘potential’ as the depicted adjacent screw to the positive terminal at the rear of the tank.

So I tried this but after leaving the bike for 2 days, I would attach the charger and it would just say the charge is full. Not sure what I am missing here.

It could simply be your battery is full. I use a tender not a charger they are two separate entities with different modus operandi. Optimate has always worked well for me and continues to do so!

Oy, have any of you wonderful folks used an Amplink? (Rowe - Amplink) I just got around to putting mine back on and love it. Denali has a similar product you can use with a CANBUS system but on the RNine you can't use them………

Not sure where you are getting the impression you can’t use them on the R Nine T. Although not listed if you use the Hex VIN converter you can enter your VIN and it will tell you what model is suitable for your R Nine T. I recently fitted a Denali one to my 2023 Pure.

Hex EZcan also works. The Denali unit is a HexEZcan simply rebranded and utilises better connectors to connect to the Denali aftermarket options, the Denali also provides a better selection of connecting leads and splitters! Both units are made by the same company Hex Innovate!

Above is correct as circled!
I simply routed the cable downwards and cable tied it adjacent to the rear brake reservoir for easy access!

Ah sure I forgot to do it on the other category. I'll do it soon.

I see so I will have to still unbolt to lift the tank up.

Do a search on the forum there’s plenty of information readily available. Just fit the lead to the posts behind the tank. The simplest solutions are often the best!
