    I have a 123 for my ancient Volvo Penta AQ 170 boat engine. Initial set-up went fine two years ago. Recently I noticed flames comiing out of the carburators so I thougt that maybe the ignition timing setting went a bit too early. I tried to readjust it and removed the ground cable from the 123. My expectatiion was that it should be possible to use the procedure for the initial timing setting with the green LED again. But it's simply not working. Any hints? In meinem Volvo Penta AQ 170 Bootsmotor ist eine 123 verbaut. Da zuletzt Flammen aus dem Vergaser schlugen, dachte ich, ich überprüfe mal wieder den ZZP, weil er ggf. etwas in Richtung "spät" verstellt werden muss. Ich wollte die Grundeinstellung wieder mit der grünen LED laut 123-Manual herstellen, aber die leuchtet nicht mehr (ich hatte das Masse-Kabel abgezogen). Weiß jemand Rat? Gruß, Thorsten

  2. Thx for the reply. My answer took a while b/c we were on vacation. The distributor cap und rotor are as new. In fact the motor has run only for 10 h or so after I fitted the 123-ignition. I am aware that the green LED is only supposed to help setting the static timing. However, after I remove the ground (minus) connection, it should work, schouldn't it? I am somehow afraid, that the non-function of the green LED indicates that theres is something wrong with the 123?

  3. Dear Thorsten, Any hints are: -Please check the distributor cap and rotor. They might be worn out. -The green LED's only functionality is to help you set the timing. When the light does not seem to work please check the timing with a timing light at 2000 rpm. Hope this helps. If not: let me know (preferably by e-mail, as I don't check this forum every day). Best regards, Leen, Leen APK

  4. Dear Thorsten, Please set the timing at 2000 rpm with the stroboscopic light. When this works, don't worry about the led. When this doesn't work please send in the unit to have it checked, with a note to describe the problem. Best regards, Heidi, Leen APK

  5. Dear Heidi, as the engine won't start there is no way to check it at 2000 rpm. After having excluded a variety of other potential reasons the most likely culprit seems to be the 123. So your offer to have it checked is appreciated. To which shipping adress shall I send it? BR, Thorsten
