And Its Really Pissing Me Off. Its The Thrid One. I Dont Drive The Car, But I Start It Up Every Other Day And Let It Run.when The Car Sits, The Battery Is Disconnected.the Condensor Has Been Replaced, I Have No Idea What Is Doing This, But It Is Getting Expensive. Its A 75 Electra W/a 455. Any Body Have Any Ideas
Could be the windings in the coil are shorting between layers. Can you check the primary side resistance with a digital ohmmeter? Should be around 0.7 ohms.
I agree, a bad coil will eat modules. The coil in cap design results in high coil temperatures. Best thing to do is go with a separate oil filled coil. MSD makes a coil cover with a terminal to run an external coil. MSD8401, I believe is the part #. The MSD 8200 coil is a good american made coil.
I have seen cheap modules do the same thing. I am not pointing the finger here, but it is easy to choose the cheaper of the two units, not knowing what makes the mpore expensive unit more expensive. The more expensive units use better components, and more of them to protect the switching transistor, which is what usually fails. It is also possible that the unit's sitting is limiting air flow through the engine compartment, and overheating the distributor. Are you using the compoiund enclosed with the module, and is the unit sitting flat in the distributor? One other thing to check is the vehicle's grounds, all of them. An intermittent ground can cause its share of surges. Some suggestions... Ray
don't forget... The oldest most common cause of failure on these is not cleaning the old heat-sink compound off and applying a new (thin) coat on installation of the new module. Hope this or the coil idea take care of you!
You might also check that the ground strap is in the cap. If that is not doing it's job, you will fry parts.
Three of us say it's a coil going/gone bad (I'm number three). I had this same problem once and discovered that when the coil heated up, it delovoped a short that would blow the modual everytime. The coil was not very much something like $15.00, but that was about eight years ago.
are you puting the right grease under that will blow it. could have a bad pickup coil and once you move the wires by changing module it connects for a short time. otherwise its coil or voltage to module. andy
Dave is worried about you guy. Go visit him. Click Here "Will someone that still has access to the V8 site PLEASE go to the Sparky's Corner section and rescue garyd from there and the ex-Mallory "tech". " IgnitionMan And please don't shoot the messanger.
thanks guys. well i put a new module in but same thing pop, now i did see sparks come out from under the car at night time by the starter. i thought back and back in 1997,my starter broke in germany, the nose cone split, so i made 1 outta two.im starting to thing it has something to do with that. also my after market temp sending unit wire(mechanical ) got real hot and melted into the ashtray. so id love to remove the starter, but the problem is trat i have taarps on the ground and there is water on it and on top of the water is you guessed it OIL, so im gonna towin it with my escort enough to remove the tarpsa nd remove the starter.but right now ithanksts hot as hell odwn here and the insects are terrible.im gonna get one of theose high torque starters for the buick.i hope its not the coil. the coil is an acell super coil and that thing cost me 50$.
