    Default Need a new timing light- options?

    Gents-
    I need to replace my old Craftsman timing light- it has no advance adjustment ability, or tach.

    I'm looking at a couple Innova timing lights:

    http://www.amazon.com/INNOVA-3568-Di...ds=innova+3568

    They both seem like decent timing lights, and the advance feature is the most important to me.

    Is the 5568 worth the extra $30 for an amateur hack like me? It can read dwell and voltage, unlike the 3568. I do like that is comes with a case, and dwell could be useful- which has me swaying in the 5568 direction.

    Also, any other options I should be looking at in the $100-$150 range?

    I've got the 5568. Works a charm. Did all the testing on the new ignition boxes with it.
    I enjoy talking to you. Your mind appeals to me. It resembles my own mind except that you happen to be insane.

    I have the 5568. It is a nice unit. I do like the fact that it reads voltage, has a case and the cord is detachable. Make up some leads with male/female connectors and keep them in the box for easy connections. I think its worth the extra $30, plus its a one time purchase. I use it on my 78 308 GTS.

    Regarding the tach, it does read double the value, (1k on engine, reads 2k on tach). I have the 12v+ power coming from my XDI circuit board which was the original feed for the coils, (yellow wire).

    Just switch it to 4-cycle mode and it should read correctly.

    I did that and no luck. I'm wondering if it is a function of the 78 USA version (originally two distributors and two coils, although the coils were fed by the same yellow wire) or a function of the XDI where it fires the plugs twice per cycle.

    Thanks folks- just ordered the 5568 from Jegs for $100. A no brainer.

    That shouldn't matter when you're on the secondary side.

    That's what I assumed. The 2-cycle/4-cycle setting should account for the XDI's DIS style design (but I stated it backward, you should be on the 2-cycle setting for DIS). But anyway, if you switched that function, I don't know why it didn't work!

    I don't know if I tried it on the 2 cycle mode. I'll try that in the spring.
