I am one of the brave souls who purchased the Peugeot Razmey engine off 1977 mopeds. After studying the immense threads regarding the issue of getting a proper spark, I have yet to achieve a spark large enough to get the engine running.

After looking through everything already posted on the forums about it I have found about two or three different wiring diagrams/photos and still feel like I have been running in circles. I was just wondering if anyone would be able to provide a final, successful wiring diagram on here that I could use to get this ped finally running.

First thing is to differentiate the kill & ground wires (both yellow w/green stripe). mine was shipped mis-pinned & caused me trouble a few years ago. the box was killed because of the wrong pin-out, which made me question everything. The ground wire is soldered to the metal chassis of the stator. Make sure that connector is pinned like my picture (promise). that get's you spark, if you wire it like that & don't get spark... i recommend getting another box (sorry to say)

then I found a diagram of a CT110 somewhere & some other source that corroborated it. It was a bit of a leap of faith because the box was blown though. The Peugeot boxes on treats are inexpensive & work great, as do those honda boxes.

Has anyone got a wiring diagram for the rear lights as when I put the rear fog light on the reverse light comes on someone has been messing with the wiring so I don't know if it is wired right any help please

The horn on my 1999 T reg. Boxer failed recently (despite having worked for the MOT 2 weeks earlier). However I do not have a wiring diagram to be able to diagnose the problem. My Peter Russet manual doesn't have one. On visiting my local Peugeot dealer I was told that their computer system would no longer come up with the details (a couple of years ago they had been very helpful in helping me sort out the wiring of my fuel gauge). I notice that the horn has a 4-wire cable. There is a Toad alarm fitted but I am assuming that it's still the original horn.

Hi. My M/H failed the MOT recently due to horn problems. ( never use the thing) I found that if you pressed down on the steering wheel it would then work. I removed the steering wheel, and found that one of the spring contacts in the columm, was making intermittent contact, with the contact rings under the wheel. ( I think must have been like it from new). Bending the contact up slightly solved the problem.

On my particular Boxer the long panel with the Peugeot Lion Emblem can be removed by undoing the eight self tappers which reside in the black recessed panel. The long panel itself is unclipped at each end. The horn is directly below the nearside headlight. It can't be seen easily but it can be felt and removed with a 10mm socket on the centre securing screw. The contacts on my horn were, as suggested dirty [despite very protective covers] but cleaned up quickly with contact cleaner.

I haven't got round to fitting a louder horn...yet. . (lol) But then I don't use it very often...usually after managing to avoid someone else's mistakes..which is really a waste of time, of course. >:-)

Thanks to Alan G's comments I had a look behind the front bumper (at nearside) and found the horn. (The easily visible item near the battery I thought was a horn for the Toad alarm AND vehicle was actually solely for the alarm: The original vehicle horn was still in use for that purpose.) I found 12v appeared at the horn push-on connectors when I pressed the switch, but no sound. I tried wiggling the connectors and hey presto - it worked. The connectors were obviously tarnished so I slide them on and off a few times and put some self-amalg tape over the (splitting) rubber boots. All is OK now!
