Re: generator light staying on conundrum

Could be. Rick Jones' book shows two pertinent wires coming through the kill switch. One is a green wire that goes through the fuse in the terminal board and then to the ignition switch...I think that is then routed to the coils in some fashion. It also shows a blue wire going to the starter relay a...

Re: generator light staying on conundrum

He does indicate a 50 ohm resistor could be used, connecting one end directly to the input side of the coils. He also says that the resistor could get very warm. Is the resistor still working? What if it has failed? Remember, the resistor is only used to help continue charging if the gen lamp bulb f...

Re: generator light staying on conundrum

Snowbum talks about using something like a 470 ohm resistor, although he prefers the 330 ohm resistor for inside the tighter instrument pods like the /6/7. Wattage is around 1 watt. Could use of a 5 ohm resistor have resulted in a slow failure of some kind that has now cropped up a year later? Kurt ...

Re: Caliper rebuild snag

He's OK. He's working hard to update and add content to his website.

Re: Troubleshoot help. No Spark R90/6

An R90/6 won't have a beancan ignition system...that came later. That "box" that Charlie showed is the "brains" of the ignition system...technically not a booster. It is nothing more than an electronic switch, reading the signals from the Hall effect sensors that are on the points replacement plate....

Re: Can a /6 starter relay replace the dreaded /5 Relay?

Snowbum never mentions the use of a /6 relay in place of the /5 relay. His web article is all about modifying the existing relay. If it was a simple matter of using a later relay type, I would think he would have offered that as a possible solution rather than getting into the /5 relay. Kurt in S.A.

That's very different. Never mind!

Re: Troubleshoot help. No Spark R90/6

The fact that you say that makes me think it is one of the two items I did not replace, the booster and the electronic ignition. If it is not fuel related, I have a feeling it is one of them... Since you can't ride the bike without an ignition system, your only choices are to 1) remove the booster ...

Re: Troubleshoot help. No Spark R90/6

Snowbum talks about the boosters...it's for points bikes and it helps control the current coming across the points, keeping them from arcing or at least from burning out. The electronic ignition (Dyna III anyway) has no points...the Dyna box/brains is just an electronic switch which replaces the poi...

Re: Troubleshoot help. No Spark R90/6

I have the Dyna III on my /7...no booster...still don't understand why you need the booster with an electronic ignition.
