Heat is the killer of electronics Posted by Ari [Email] (#2847) [Profile/Gallery] (more from Ari) on Mon, 26 Apr 2004 07:49:36 In Reply to: Re: intermittent stalling now no spark, Tim O, Fri, 23 Apr 2004 09:33:29 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Heat kills electronics. It's tough to say exactly what the failure mode is in this case, but it does sound like putting the heat sink compound on was too late.
There really is no way to test the IA other than what you've done. If you've swapped distributors, you've swapped Hall effect sensors. So unless you happened to get a used distributor with a bad Hall Effect sensor, the best guess is the IA. The 'no bounce' on the tach is a giveaway. About the only thing I'd check would be the connector on the side of the distributor. They usually don't fail, the break. That's a failure, but an obvious one.
