Interesting - but you then still have points eh ?

I'm thinking about ordering a couple of these as it is a very tidy set-up and also very 'reversible' if I want to put points back in.

For the price the Starfire unit is a neat alternative and follows the same design as the RE5 CDI that uses points to trigger the system.
The Accent unit isnt cheap, but its simple and compact. Its by far the neatest unit ever made for sure, and the quality is first rate.
I'll have to look at a Starfire for the 69 Titan, mostly to help unload the rather weak charging system.

This is known as a first generation electronic ignition. It still uses the points to tell it when to spark but replaces the condensors, it takes the 'load' off the points, so the only wear is the rubbing block. I doubt that it can actually use less watts with all the other componets still the same. So this is a very expensive 'condensor'.

Not quite true, Mr Bond.

My GT750 has been running a similar system (that I built) for about four years now. It's been completely maintenance-free and I run a 4 AH AGM battery on the bike since removing the electric starter.

I stand corrected. I am not privy to all the mysteries of electronics, just know enough what not to touch so I won't get shocked, at least not too badly.

In principle it's the same as the old TAI Transistor Assisted Ignition which used the points to signal the system but they took almost no power and did not arc or wear out as fast.

I used a twin channel system like that back in about 1980 and the points seemed to stay in tune longer. In this case, there appears to be a CDI aspect to the circuit, but it's still triggered by points.

That would make it closer to the old Yamaha magneto system but with battery rather than AC on the LT side.

better to get an electronic trigger and say an Ignitech system for about 130 euros and have a fully programmable system.
