What's this circuit board from?

Any idea? it's not from a 1981-4 R100RS afaik.

There are 6 long connectors on one side and 4 on the other.

Look at photos 3 and 4 here:

These are from a /7 pod.

It has connection lugs for electronic tach so must be post 1977 (?) I think. If you say not 81-84 then it must be 77-80??

Looks like a /7, as Kurt points out, when comparing to photo. I got a 78 /7 board on my workbench. I'll take a look and see how it compares to what you got.

Its a /7, looks exactly what I have (78 /7) on the bench...apart for odometer repair.

Yes...1978-80. You can tell because: 1) it has the three small tabs for the electronic tach...and, 2) it has the high beam indicator off to the side...these are NLA

1974-77 will have no tabs for the electronic tach, but will still have the high beam off to the side...these are also NLA

1981+ will have the three tabs for the electronic tach and the high beam is one of the central bulbs (IIRC, they did away with the "brake failure" indicator to make room for the high beam indicator)...these are still available.

Thanks for the replies. The lateral offshoot for the high beam indicator can also be seen on the 81-84 circuit boards, at least it can on the two examples I have. It's obsolete for the 81 on models so yes, the active high beam light is the central bottom one. This one has 5 long connectors, on either side, differently configured.

I want to put the one in the first post on ebay. If anyone here wants it for post +$6 (one stubby of cider) it yours.

So, it sounds like it's for the instruments with electronic tacho b/w 77-80. One folded copper tab is broken (the top light, easy repair with foil) and a locating tab (left one )for the circuit board at one of the indicator lights is broken off. That shouldn't have an effect on function. I have plugged this into my instrument multi plug to check function, and it worked. Having said that, the top light (broken tab) and the 2 lower lights didn't light up, but they don't on mine either due to a problem in the loom.

I'm sorry...let me clarify: on the 1981+ version, there is still a tab for the high beam, but if you examine the circuit, it is non functional.
