The way the BFU works is it passes the current to a pair of bulbs in the circuit through a pair of coils, each wound in opposite directions next to a reed switch. If both bulbs are working, the fact that each coil is wound in opposite directions to the other means they both produce a magnetic field in the opposite direction - a North pole and a South pole of a pair of bar magnets if you will. These cancel each other out so the reed switch doesn't move. However if one bulb is blown (or there is a bit of resistance in the circuit like a bad earth or even a different make bulb) then there is only one magnetic field which operates the reed switch or in the case of resistance, a smaller magnetic field. The larger overcomes the smaller and operates the switch. Note that if both bulbs or the fuse for that circuit fails, no warning will be given. With this in mind, you can imagine the wires carrying the current have a finite capacity of current. As such adding extra bulbs in the form of a trailer board/trailer lighting "downstream" of the BFU will overload the wires and burn them out resulting in that circuit being inoperative. Therefore the towbar wiring must be connected "upstream" of the BFU, i.e. before the power to the various monitored circuits passes through it. Obviously this means the trailer lighting isn't monitored. Meanwhile i'm waiting to see what Alan buys (assuming he does) to know if that woulod be more suitable as a towcar.

Both my trailers are 760kg (the limit for unbraked trailers - but in practice they are easily strong enough to carry much more than that). Fitting a towbar to the RB is a possibility, but I’m not all that keen - a boot spoiler and a towbar might look a bit daft! I suppose it could happen though, perhaps I’ll start looking out for a 240 towbar in slow time. Probably the cheapest solution would just to keep the Skoda. It will be nearly 10 years old by then, so won’t have much resale value, but it is a great workhorse, very well looked after (I’ve owned it from new) and only costs £30/year tax. Part of this idea was to reduce the number of cars and bikes I have. Alan

I'm aiming to get down to just two bike as of this coming summer - so dispose of the CCM off roader and the 1976 Suzuki. I do have one of these trials bike carriers that would be ideal for either of those (but still needs a towbar to mount: ... yes that really is on a Fiat Panda with Dutch plates, and the bike did go all the way to Limburg (and back) on that. Unfortunately that would not solve the problem as my triumph weighs about 250kg, and the Royal Enfield nearly 200kg: I have a really nice Erde two-bike trailer that can carry both with an all up weight of no more than 700kg which works really well behind the Skoda. I could just keep the Skoda, it doesn't cost much to run, but I'm aiming to reduce rather than increase the number of vehicles I run over the next 10 months. Alan

You'd still need a ramp but there are lashing points if memory serves inside so the bikes didn't move when you were "playing" away from the lights.

I'm not letting on about what Project Volvo might be yet - just in case it turns out to be no good in the flesh and I don't buy the motor car. :-)

I guess it depends on why you are moving the bikes. Some of our lads used a trailer to take bike(s) to a ride-out - riding a 49cc moped to a meet any distance away can quickly become tedious! On longer runs, we would sometimes use a support van, carrying spares, tools, maybe a spare bike or two. This could also act as a 'sweeper', thereby giving following drivers advance warning of slow-moving traffic and the riders a greater degree of protection from faster vehicles. Regards, John. What you refer to as a trials bike carrier Alan is very like the type of thing that we used to carry mopeds and autocycles. They worked very well. J.

When I really think about it I probably don't really need either trailer. The 3/4t ramp back is really handy for collecting building materials and taking stuff to the council dump, friends borrow it occasionally for the same purposes but if I'm really candid I could live without it. The bike trailer is another nice to have: there was a time when I did quite a lot of green lane riding with some mates, and it was really useful to get two off road bikes to Derbyshire or Wales for trips away. If I'm honest with myself I'm probably not fit enough to do that any more (after a couple of hip replacements) so I'm unlikely to need it for that again. I do use the bike trailer for collecting project bikes from time to time, but again I do that much less now (and I'm trying to reduce my collection of bikes). In conclusion: the answer is more along the lines of a lifestyle change (over the next 18 months) to reduce the number of bikes, motor cars and trailers I own so I can fit in a smaller space when I relocate to spend my dotage somewhere by the sea. I will probably always own the Triumph and the Royal Enfield bikes, but I'll sell the Suzuki 2 stroke and the CCM in the spring - at the same time promise myself that I won't buy any more project bikes. I think I could reconcile the Porsche and the Skoda Superb estate into one vehicle: something like the Tesla Model X would fit the bill (and I suspect there will be a bigger choice of similar EVs in 2 years time - and with it real prices of EVs will continue to fall). The RB is staying whatever - which gets me down to just two motor cars and two motorcycles - at that point the need for the two trailers goes away. There is a fly in the ointment: there is another Volvo project I'm quite keen on and will have a look at later on this week. If it is okay it could be one last project - and 18 months sounds like a nice timescale. It has been a really useful to go through the estimate process (as it would have been called in the military) - as always this forum has been a really useful sounding board. :-) Alan

I have this very morn acquired a Volvo 240 towbar from a very generous ex-member of this forum, it is free of charge but just needs collecting from Coventry. I'll try to pick it up (about a 100 mile round trip, but I'll try to combine it with some other requirement) in the next month. Much to my chagrin I'll fit it to the RB sometime over the next 18 months and install some electrics. That part of the jigsaw is in place :-) Alan

https://www.ebay.co.uk/itm/Volvo-240...rdt=true&rt=nc ... it only reached £4,200 this time round, again failing to reach its reserve price. This was its second time through the eBay strainer, the last auction got to £5,500 (still short of its reserve) on 23 December. Perhaps the market is becoming a bit tired of 'one of the best, if not the best examples of a classic Volvo 240'? :-)
