I bought three Tiger Cubs in baskets and started sorting things out to start putting the first one together. I have a Haynes shop manual and was about to mock up the bike (model T20)and found only two wires coming from the stator. Yellow and White. The wire diagram shows the normal three wire dark green, light green, green and yellow. What have I got here? Looking for a battery box, or dose this carry a battery? I have never done one of these bikes before and am in the learning curve.

Hi Scott,

What have I got here?

Educated guess - "two wires" = 12V single-phase, "Yellow and White" = pattern aftermarket. Both wires would connect one each side of a rectifier, doesn't matter which way 'round as they're both carrying AC.

Risking stating the obvious, don't rush for one of these. Known as the Lucas RM13/15, as standard they were rigged to produce 6V, but can be connected to supply 12V; however, the output wasn't huge when they were new, any are at least 50 years old and the thin wires of the open coils were prone to breakage by vibration, if nothing else. frown Also, if the wiring diagram's the same as in the contemporary Triumph 'C'-range manual, it has a misprint that means all some of the 6V functions don't work if you follow the diagram. shocked

Finally here, if the alternator stator you have is 12V, bear in mind that it'll need a Zener diode - or the Zener and the rectifier replaced with a combined rectifier/regulator - that the '62 wiring diagram won't show.

The original 3-wire alternator indicates the bike would have had a battery originally, the battery provided at least some of the 'regulation' laughing in a 6V system.

Hth.

hi scott,

I'm over on the cubsite as well and there's a lot of info there

big D cycles have parts books online to view, and the cubsite has some manuals too.
Greystones in the UK have loads of parts and a decent website that will allow comparison of parts even if you don't buy from them.

I sympathise as although I have a complete 56, I bought a 60 on a whim and the PO has completely stripped it to the TINNIEST part and labeled nothing.

I had to go through each paint can/box and sort out the dead leaves, dead mouse and lawn mower parts from cub ones and bagged everything up and ticked off the parts list.

1962 is a very nice year to have.

Following on from what AngloBike has said:

Mike Estall (Cub Guru) has a consolidated parts list available which you might find useful - as you have a bunch of bikes from different years:

mikeestall@hotmail.com

His book: The Triumph Tiger Cub Bible (Veloce) is my favourite bike book of all. It is not technical, in the rebuilding sense, but has loads of interesting information and a year by year overview. Expensive though! Some used copies were going for daft prices, but I think it has now been reprinted.

Thanks for the reply. After sitting down and looking at the diagram in good light at my desk I think I can work this out. A/C is A/C. I will build my own harness with the minimum, lights, horn, break light. I will put a battery in the system. Thanks again for your input.
Scott

you don't say what state the rbuild will be. Or much about the bikes as-is

The nacelle mounted switch was a very complicated bit of wiring which brought in more elements of the alternator as you demanded pilot lights and or main lights.

if you're doing it up as a trials type you might want to convert to 12v and just rely on bar mounted switch gear. (or a headlight switch)

Don't know what your expertise level is but ime I wouldn't go just by the diagrams in the Haynes manual. frown I have the Lucas Motor Cycle Electrical Equipment Service manual - it's pretty clear that, at any given time, Lucas made a given harness from smaller, more-common sub-assemblies; the Lucas manual has a number of generic wiring diagrams that are pretty close to the individual diagrams in more-specialised manuals (that's how I spotted the misprint in the early 'C'-range manual). I got my copy of the Lucas manual from British Spares.

Hth.

Scott , sounds like your on the right track

... cubs came with 3, 4 and 5 wire stators ... all 6 volt , with some of the coil taps dedicated to ignition other taps to lighting ... and some cub models had no battery

If your stator has 2 wires I'm bettin' its a single phase 12 volt deal ,
RM21 pattern. .. and none of the bikes oringinal switching diagrams are gonna work without some standard 6 to 12 volt Tweeking ...


What year and what style build are you doing ?
