Qman Posted March 31, 2006 Share Posted March 31, 2006 have alt. checked, may be bad diodes Bad diodes will not cause a jumpy tach. They will cause the idiot lights to glow though. The bushing or the electronic module in the disty is going bad. My guess would be the module as it changes with temp. Easy to replace either the module itself or the disty.

4x4moose Posted April 1, 2006 Author Share Posted April 1, 2006 disty shop? like a auto electric rebuilder? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted April 1, 2006 Share Posted April 1, 2006 Well - there's these guys - local for me, but they will ship. They rebuild a lot of stuff for local shops. Have used them three times myself now, and I've had several friends go there. Excelent work, and they can do the vacuum advance unit as well. http://www.philbingroup.com/ Might be someone local that does this sort of work too - good luck.
