istruggle2gate11 Posted January 11, 2006 Share Posted January 11, 2006 Hi all, Just going through my collection of bits, found a 35DM8 dizzy, I think this is the one which goes to the remote amplifier, question is how can I test its a good un off the bench? Ive placed my multi meter on the wires and spun the dizzy, the meter does register RPM and it varies correctly (used a power drill to spin it). Is there any other tests which can be done? Thanks Roger Quote Link to comment Share on other sites More sharing options...
Niall_CSK Posted January 14, 2006 Share Posted January 14, 2006 The only other things I can think of are :- Make sure the Vac advance is OK, suck on it to check for leakage & movement of the base plate. Check the mechanical advance & springs by holding the gear/spindle in a padded vice and gently twist the rotor arm, clockwise I think, should go about 10 deg then snap back when you release it. Both these checks are easier to do with the engine running and a strobe lamp but I guess you want to be sure before you put it back. Have a search for details as I have written about this several times. Try to squirt some engine oil in under the base plate for the bob weight & spring mechanism while you have it on the bench, then leave it vertical in a warm spot to let any excess run out of the darin hole before you put it back. WD40 is OK but it evaporates after a while so is not so effective long term. Quote Link to comment Share on other sites More sharing options...
