Project Board / Re: Teds new project a CB500 K1 mostly version 0.5 circa 1972.

The oil light switch decided to stop working when I was going to set the static timing - it just stayed off so replacement via NJ fitted today.
Due to a raft of household type jobs & Wendy's Freelander decided it did not want to crank over I've been distracted. Thank goodness I had Home Start on her Insurance. Iffy starter motor so RAC Smart Service are fitting it on our driveway on Monday.

It will be after the weekend now before I can do any more on the 500. Not sure how it's affecting members here but we had the CH on again last night & this evening.

Deffo try setting 4 then. 👍

Is you rev counter designed to work with electronic ignition the switching signal profile might be unsuitable.

As you are dealing with an inducted circuit it might be possible to dampen it. Electronics is not my forte.

Might be worth trying the impulse wire on the other side if the LT connection a blue say. The signal via the coil  primary windings might give it more signal oomph?
Odd if no details of how many winds round the coil wire is needed in the instructions.

I suspect the impulse measurement signal would be different if it includes the circuit through the coils unless it's designed to work on the feed side as this would not be affected by the coil resistance - your logic to connect on the B&W side makes more sense. Do the instructions help?

Presumably the unit itself has three connections?
Power and earth to the unit itself  plus the impulse wire that measures the number of  circuit impulses within the unit to translate that into the analogue reading?

I would have thought it ought to be connected to the blue or yellow on the points side - or do the instructions say on B&W side?

The manufacturer of your unit need to employ an accurate translation for their instructions - those are gobbledygook.
My thinking is:-
If one set of points operates  two cylinders with a wasted spark you are getting four signals for one 360 deg of rotation so setting 4 on the left side of the first table (4C-8P).  If its a 4 lobe unit. or is it setting 2 FFS I'm lost already but...

Presumably  if you get the setting wrong it will read either half the true revs or double .
Either way you should get a reading assuming the power supply wiring is polarity correct and earthed.

Update:- I keep changing my mind between setting 2 & 4 either way I cant see why you do not get some sort of output givig a reading

An electronic rev counter works by converting the rotational impulses into either a digital or analogue display.
A rev counter for a 4 cylinder car will not work on a 3 cylinder one though manufacturers might fit a circuit so it works on both. I fitted an Audi 100 GL car  rev counter into my old Mini as both were 4 cylinder vehicles.
I assume yours will be specific for a 4 Cylinder motor cycle that uses  the wasted spark system - not a distributor

If it works on the  LT side of  the impulses will it not be related to the number of sparks generated for one crank rotation?
Not as such affected by the HT coil side?

Welcome Phil, when you can be good to see a photo of your 650.
There is a qualifying period before you can post pics.

If it helps I'm pretty sure I have my original one that I replaced with a less than perfect aftermarket one. Yours for the cost of postage if it helps as a practice part. PM me if this is of any use.(Yes it is sloppy).

Oddjob knows how - sadly Ken is currently suspended here.
