Edit: I didn't see that there was a page 2 of the thread when I posted, so I missed mraxl's post. I forgot the numbers were on that diagram too.

The manual does have it, as well as other measurements you can make on parts of the system. It's on page 120 of the H shop manual.

Low speed coil: 5 ohm between blue and green
High speed coil: 200 ohms between green and white

You won't get exactly these readings, but if you're in the ballpark you're OK. For the low speed coil, subtract the resistance of your meter leads (touch them together and read that first) from your reading so they don't add to it.

thanks Guys I didnt see that page 120 , I have missed it for 50 yrs !!!!!!!!!!!!!, mine test ok

well I cursed my self checking spare altinator , the one on my bike failed yesterday , can any one supply a low speed coil for a H2 750 72 model

Rex's Speed Shop used to sell them. You might check with them and see if they can help.

I believe Rick's Motorcycle Electrics in New Hampshire will rebuild the whole stator.

I realize the OP didn't ask about the ignition rectifier, but...

If you use the 1,000 volt diodes you have shown above, you don't need the double diodes with equalizing resistors for the white wire. That was needed for the stock 400 volt diodes.

You can use all 1N4007 or all 1N5408 diodes if you want to. I liked to use all 1N5408, since they have a 3 amp rating and might survive some oddball problem better than the 1 amp 1N4007 version.

That's a "1" before the "N" in both types, by the way.

Thanks Jim, next build I will use heavier diodes. So far it has not blown up lol. I do miss your old site with all the ignition information. I have found different boards are used on the CDI boxes for the H2s so maybe that is tied into improvements too?

Many guys have used all 1N4007 diodes with no problems. Yes, they made some small changes to the CDI components along the way. There's no telling it they were improvements or just changes to save money or for parts availability.
