Cpt. Stooby Posted October 23, 2011 Share Posted October 23, 2011 My ea 82 is not getting a ground At the ig. Coil. I had to replace the coil as tge secondary resistance was bad,but it was not the.entire problem. Any ideas or suggestions Quote Link to comment Share on other sites More sharing options...
Cougar Posted October 24, 2011 Share Posted October 24, 2011 The ground is made through the mounting clip of the coil I believe. Make sure there isn't any rust between the case and the mounting clip. Also make sure the connection to the engine is clean. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 24, 2011 Share Posted October 24, 2011 Where are you looking for a ground? Ignition coils themselves, as a general rule, are not grounded except through the action of the distributor - which will open and close the ground connection to expand and collapse the magnetic field which induces the spark current in the secondary winding. Now - the coil *bracket* on EA82 fuel injected models needs a ground connection through the mounting ears - but it's for the ignition transistor amplifier - not the coil itself.

Cpt. Stooby Posted October 25, 2011 Author Share Posted October 25, 2011 Its fuel injected, im looking for whereever it grounds, but it grounding through the.distributor makes sense because isnt there a piece that can go bad in the distributor that is nearly impossible to test.

GeneralDisorder Posted October 25, 2011 Share Posted October 25, 2011 The ground is through the ignition amp on the coil bracket in the FI models, not through the distributor. The distributor on the hot-wire MAF cars is simply a crank position sensor and a way to distribute spark to the various cylinders. It does not directly trigger the coil - that is done by the ECU. Check the coil primary and secondary resistance. If that is good then check for the ignition pulse while cranking from the negative side of the coil to the negative side of the battery - the light should pulse on and off while cranking. If it doesn't then replace the ignition amp (the coil bracket). GD Quote Link to comment Share on other sites More sharing options...
